Nature of Business | 1. Nature of Business GI Dynamics ® Diabetes mellitus type 2 (also known as type 2 diabetes) is a long-term progressive metabolic disorder characterized by high blood sugar, insulin resistance, and reduced insulin production. According to the Centers for Disease Control and Prevention (CDC), people with type 2 diabetes represent 90% of the worldwide diabetes population, whereas 10% of this population is diagnosed with type 1 diabetes (a form of diabetes mellitus in which not enough insulin is produced). Being overweight is a condition where the patient’s body mass index (BMI) is greater than 25 (kg/m 2 When considering treatment for type 2 diabetes, it is optimal to address obesity concurrently with diabetes. EndoBarrier ® The current treatment paradigm for type 2 diabetes is lifestyle therapy combined with pharmacological treatment, whereby treating clinicians prescribe a treatment regimen of one to four concurrent medications that could include insulin for patients with higher levels of blood sugar. Insulin carries a significant risk of increased mortality and may contribute to weight gain, which in turn may lead to higher levels of insulin resistance and increased levels of blood sugar. Fewer than 50% of patients treated pharmacologically for type 2 diabetes are adequately managed, meaning that medication does not lower blood sugar adequately and does not halt the progressive nature of diabetes of these patients. The current pharmacological treatment algorithms for type 2 diabetes fall short of ideal, creating a large and unfilled treatment gap. Our vision is to make EndoBarrier EndoBarrier ® Since incorporation, the Company has devoted substantially all of its efforts to product commercialization, research and development, business planning, recruiting management and technical staff, acquiring operating assets, and raising capital. The Company currently operates in one reportable business segment. EndoBarrier History In 2011, the Company began commercial sales of its product, EndoBarrier, which was approved and commercially available in multiple countries outside the U.S. at the time. In 2013, the Company received approval from the U.S. Food and Drug Administration (“FDA”) to commence its initial pivotal trial of EndoBarrier (the “ENDO Trial”). The Company announced its decision to stop the ENDO Trial in the second half of fiscal year 2015 and thereafter announced that it was reducing headcount by approximately 46% as part of its efforts to restructure its business and expenses and to ensure sufficient cash remained available for it to establish new priorities, continue limited market development and research, and to evaluate strategic options. In the second and third quarters of fiscal year 2016, the Company took additional actions that it thought necessary to evolve strategic options. These actions resulted in non-recurring charges totaling approximately $1.1 million, including $0.4 million related to restructuring charges in our second quarter, $0.6 million related to employee departures in both our second and third quarters and $0.1 million related to the early exit from our former headquarters in Lexington, MA. In October 2016, the Company received final cancellation notification from the Therapeutic Goods Administration (“TGA”) for the listing of EndoBarrier on the Australian Register of Therapeutic Goods (“ARTG”). In May 2017, the Company received notification from its notified body, SGS United Kingdom Limited (“SGS”), that the CE Mark for EndoBarrier had been suspended pending closure of non-conformances related to its quality management system required under International Organization for Standardization (“ISO”) regulations. On November 10, 2017, the Company received notification from SGS that SGS was withdrawing the Certificate of Conformance for EndoBarrier, ending the CE Marking of EndoBarrier in Europe and select Middle East countries. In December 2017, the Company received notification from the Medicines and Healthcare Products Regulatory Agency (“MHRA”) that all EndoBarrier delivery systems (liners) in inventory needed to be returned to the Company. In August 2018, the Company received approval of an investigational device exemption (“IDE”) from the FDA to begin enrollment in a pivotal trial evaluating the safety and efficacy of EndoBarrier in the United States pending Institutional Review Board (“IRB”) approval, which was received in February 2019. Financing History From its inception in 2003 to its initial public offering (“IPO”) in 2011, the Company was financed by a series of preferred stock financings. In September 2011, the Company completed its IPO of common stock in the form of CHESS Depositary Interests (“CDIs”) in Australia. As a result of the IPO and simultaneous private placement in the U.S., the Company raised a total of approximately $72.5 million in proceeds, net of expenses and repayment of $6.0 million of the Company’s convertible term promissory notes. Additionally, in July and August 2013, the Company issued CDIs on the Australian Securities Exchange (“ASX”) through a private placement and share purchase plan, which raised a total of approximately $52.5 million, net of expenses. In May 2014, the Company raised an additional total of approximately $30.8 million, net of expenses, when it issued CDIs on the ASX through a private placement. On December 20, 2016, the Company completed a private placement issue of 69,865,000 CDIs (1,397,300 shares) at an issue price of A$0.022 per CDI raising approximately $1.0 million, net of issuance costs. In January 2017, the Company completed the issue of 12,481,600 CDIs (249,632 shares) to eligible investors under a Security Purchase Plan for approximately $0.83 per share of common stock (A$0.022 per CDI) resulting in net proceeds after issuance costs of approximately $0.2 million. In June 2017, the Company completed a Convertible Term Promissory Note (the “2017 Note”) secured financing with its largest stockholder Crystal Amber Fund Limited (“Crystal Amber”) for a gross amount of $5.0 million. The 2017 Note accrues interest at 5% per annum compounded annually. Crystal Amber is deemed a Related Party of the Company for ASX purposes due to the size of its ownership position. The 2017 Note was originally due on December 31, 2018 and contains provisions for conversion during its term and is also subject to security arrangements in favor Crystal Amber (See Note 10 of the Consolidated Financial Statements for a more complete description of the terms and conditions of the financing). In January and March 2018, the Company raised approximately $1.6 million in an offering of its CDIs to sophisticated and professional investors, including certain existing investors in Australia, the United States and the United Kingdom. In May 2018, the Company completed a Convertible Term Promissory Note (the “2018 Note”) and Warrant (the “2018 Warrant”) financing with its largest stockholder Crystal Amber for a gross amount of $1.75 million. The 2018 Note accrued annually compounded interest at 10% per annum until its conversion into CDIs on June 30, 2019 (as described further below). The 2018 Warrant will expire on May 30, 2023. Crystal Amber is deemed a Related Party of the Company for ASX purposes due to the size of its ownership position. (See Note 10 of the Consolidated Financial Statements for a more complete description of the terms and conditions of the financing). In September 2018, the Company received commitments for a private placement of approximately $5 million in an offering of its CDIs to sophisticated and professional investors, including certain existing investors in Australia, the United States and the United Kingdom. The first tranche of $2.2 million closed and cash was received in September 2018. The second and final tranche of $2.8 million was contingent upon stockholder approval, which was obtained in October 2018. Cash proceeds from the second tranche were received in November 2018. In December 2018, the maturity date of the 2017 Note was extended from December 31, 2018 to March 31, 2019 in exchange for payment of $394 thousand, the total accrued interest on the 2017 Note at December 31, 2018. In March 2019, the Company completed a Convertible Term Promissory Note (the “March 2019 Note”) and Warrant (the “March 2019 Warrant”) financing with its largest stockholder, Crystal Amber, for a gross amount of $1.0 million. The March 2019 Note accrued annually compounded interest at 10% until its conversion into CDIs on June 30, 2019 (as described further below). Certain specific conversion terms related to the March 2019 Note and issuance of the March 2019 Warrant required stockholder approval, which was obtained during the Annual Meeting of Stockholders held on June 30, 2019 (at which stage the March 2019 Warrant was immediately issued). The March 2019 Warrant will expire on June 30, 2024. Crystal Amber is deemed a Related Party of the Company for ASX purposes due to the size of its ownership position (see Note 10 of the Consolidated Financial Statements for a more complete description of the terms and conditions of the financing). In March 2019, the maturity date of the 2017 Note was extended to May 1, 2019. In April 2019, the maturity date of the 2017 Note was extended to July 1, 2019. A further extension of the maturity date of the 2017 Note is described below. In May 2019, the Company completed a Convertible Term Promissory Note (the “May 2019 Note”) and Warrant (the “May 2019 Warrant”) financing with its largest stockholder, Crystal Amber, for a gross amount of up to $3.0 million. The May 2019 Note was funded in four tranches between May 10, 2019 and June 28, 2019, during which period 10% per annum interest was accrued on daily outstanding principal balances. Upon funding completion on June 28, 2019, accrued interest began to compound annually at a rate of 10% per annum until its conversion into CDIs on June 30, 2019 (as described further below). Certain specific terms associated with the conversion of the May 2019 Note and issuance of the May 2019 Warrant required stockholder approval, which was obtained during the Annual Meeting of Stockholders held on June 30, 2019 (at which stage the May 2019 Warrant was immediately issued). The May 2019 Warrant will expire on June 30, 2024. Crystal Amber is deemed a Related Party of the Company for ASX purposes due to the size of its ownership position (see Note 10 of the Consolidated Financial Statements for a more complete description of the terms and conditions of the financing). In June 2019, the maturity date of the 2017 Note was extended to October 1, 2019. On June 30, 2019, Crystal Amber elected to convert the 2018 Note, the March 2019 Note and the May 2019 Note to CDIs. Under the terms of the respective notes, an aggregate of 453,609,963 CDIs (representing approximately 9,072,197 common shares) were subscribed but unissued on conversion and concurrent cancellation of the 2018 Note, the March 2019 Note and the May 2019 Note. Going Concern As of June 30, 2019, the Company’s primary source of liquidity is its cash and cash equivalents balances. The Company continues to evaluate which markets are appropriate to pursue regulatory approvals, pursue reimbursement, raise market awareness and conduct general market development and selling efforts. The Company continues to restructure its business and costs, establish new priorities, and evaluate strategic options. As a result, if the Company remains in business, it expects to incur significant operating losses for the next several years. The Company has incurred operating losses since inception and at June 30, 2019 had an accumulated deficit of approximately $279 million, a working capital deficit of approximately $3.8 million, cash used in operating activities of approximately $5.3 million and cash and cash equivalents of approximately $2.5 million. Cash provided by these activities will be used predominantly to prepare for and conduct the Company’s clinical trial, which will result in increased expenses. The Company does not expect its current cash balances will be sufficient to operate beyond the end of September 2019. The Company will need to raise additional funds through any combination of collaborative arrangements, strategic alliances, and additional equity and debt financings or from other sources. Furthermore, if the Company raises insufficient funds and is required to make payment to Crystal Amber under the 2017 Note on its maturity date of October 1, 2019. the Company will be required either to renegotiate the maturity date of the loan or to potentially cease operations. The Company expects to discuss further extension of the maturity date of the 2017 Note with Crystal Amber, but there can be no assurance that any extension will occur. The Company has no guaranteed source of capital that will sustain operations beyond September 2019. There can be no assurance that other potential financing opportunities will be available on acceptable terms, if at all. As such, if access to capital is not achieved to satisfy cash needs in the near term, the Company’s business, financial condition and results of operations will be materially harmed or the Company may be required to cease operations. These factors raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that these financial statements are issued. The accompanying consolidated financial statements have been prepared assuming the Company will continue as a going concern, which contemplates the realization of assets and liabilities and commitments in the normal course of business. The consolidated financial statements as of June 30, 2019 and December 31, 2018 and the three and six months ended June 30, 2019 and 2018 do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that may result from uncertainty related to the Company’s ability to continue as a going concern within one year after the date that the financial statements are issued. |

Summary of Significant Accounting Policies and Basis of Presentation | 2. Summary of Significant Accounting Policies and Basis of Presentation The accompanying interim consolidated financial statements and related disclosures as of June 30, 2019, and for the three and six months ended June 30, 2019 and 2018, are unaudited and have been prepared in accordance with accounting principles generally accepted in the U.S. (“GAAP”) and the applicable rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. These interim consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K (“Form 10-K”), filed with the SEC on March 13, 2019. The December 31, 2018 consolidated balance sheet included herein was derived from the audited financial statements as of that date but does not include all disclosures including notes required by GAAP for complete financial statements. Principles of Consolidation The accompanying consolidated financial statements include the accounts of GI Dynamics, Inc. and its wholly owned subsidiaries. All intercompany transactions and balances are eliminated in consolidation. Use of Estimates The preparation of consolidated financial statements in accordance with GAAP requires the Company’s management to make estimates and judgments that may affect the reported amounts of assets, liabilities, revenues and expenses, and the related disclosure of contingent assets and liabilities. On an ongoing basis, the Company’s management evaluates its estimates, including those related to impairment of long-lived assets, income taxes including the valuation allowance for deferred tax assets, research and development, contingencies, lease liabilities, valuation of derivative liabilities, estimates used to assess its ability to continue as a going concern and stock-based compensation. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ from these estimates under different assumptions or conditions. Changes in estimates are reflected in reported results in the period in which they become known. Cash and Cash Equivalents The Company considers all highly liquid investment instruments with an original maturity when purchased of three months or less to be cash equivalents. Investments qualifying as cash equivalents primarily consist of money market funds and have a carrying amount that approximates fair value. The amount of cash equivalents included in cash and cash equivalents was approximately $4 thousand The Company has $30 thousand in restricted cash used to secure a corporate credit card account. Inventory When the Company resumes commercial activity, the Company will state inventory at the lower of first-in, first-out cost or net realizable value. When capitalizing inventory, the Company will consider factors such as status of regulatory approval, alternative use of inventory, and anticipated commercial use of the product. At June 30, 2019 and December 31, 2018, there was no inventory or reserves against inventory on the balance sheet. Property and Equipment Property and equipment, including leasehold improvements, are recorded at cost and are depreciated when placed in service using the straight-line method based on their estimated useful lives. Included in property and equipment are certain costs of software obtained for internal use. Costs incurred during the preliminary project stage are expensed as incurred, while costs incurred during the application development stage are capitalized and amortized over the estimated useful life of the software. The Company also capitalizes costs related to specific upgrades and enhancements when it is probable the expenditures will result in additional functionality. Maintenance and training costs related to software obtained for internal use are expensed as incurred. Leasehold improvements are amortized over the shorter of the estimated useful life of the asset or the remaining lease term. Costs for capital assets not yet placed into service are capitalized as construction in progress and will be subsequently depreciated in accordance with the above guidelines once placed into service. Maintenance and repair costs are expensed as incurred. Lease Liabilities and Related Assets The Company adopted Accounting Standards Codification (“ASC”), Topic 842, Leases Leases At the inception of an arrangement, the Company determines whether the arrangement is or contains a lease based on the unique facts and circumstances present. The Company has elected not to recognize on the balance sheet leases with terms of one year or less. Leases with a non-cancellable term greater than one year are recognized on the balance sheet as lease assets, short-term lease liabilities and long-term lease liabilities. Using criteria defined in ASC 842, the Company determines whether the lease is a Financing Lease or an Operating Lease. Lease liabilities and their corresponding Right-of-Use assets are recorded based on the present value of lease payments over the expected remaining lease term. Options to renew an Operating lease are not included in the Company’s initial lease term assessment unless there is reasonable certainty that the Company will renew. However, certain adjustments to the Right-of-Use operating asset may be required for items such as incentives received. The interest rate implicit in lease contracts is typically not readily determinable. As a result, the Company utilizes an estimated incremental borrowing rate, which is the rate it is expected to incur to borrow an amount equal to the lease payments on a collateralized basis (or on an unsecured basis if existing debt covenants prevent further securitization) over a similar term in a similar economic environment. In accordance with the guidance in ASC 842, components of a lease are split into lease components and non-lease components. A policy election is available pursuant to which an entity may elect to not separate lease and non-lease components. For new and amended leases beginning in 2019 and after, the Company has not made the election to combine lease and non-lease components. Research and Development Costs Research and development costs are expensed when incurred. Research and development costs include costs of all basic research activities as well as other research, engineering, and technical effort required to develop a new product or service or make significant improvement to an existing product or manufacturing process. Research and development costs also include preapproval regulatory and clinical trial expenses incurred prior to regulatory approval. Patent Costs The Company expenses as incurred all costs, including legal expenses, associated with obtaining patents until the patented technology becomes feasible. All costs incurred after the patented technology is feasible will be capitalized as an intangible asset. As of June 30, 2019 and December 31, 2018, no such costs had been capitalized. The Company expensed patent costs within general and administrative expenses of $54 and $41 thousand for the three months ended June 30, 2019 and 2018, respectively, and $95 and $80 thousand for the six months ended June 30, 2019 and 2018, respectively. Stock-Based Compensation We account for stock-based compensation in accordance with the Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC, 718, Stock Compensation For awards that vest based on service conditions, we use the straight-line method to allocate compensation expense to reporting periods. The grant date fair value of options granted is calculated using the Black-Scholes option pricing model, which requires the use of subjective assumptions including volatility, expected term and the fair value of the underlying Common Stock, among others. The assumptions used in determining the fair value of stock-based awards represent management’s best estimates, but these estimates involve inherent uncertainties and the application of management judgment. As a result, if factors change, and we use different assumptions, our stock-based compensation could be materially different in the future. The risk-free interest rate used for each grant is based on a zero-coupon U.S. Treasury instrument with a remaining term similar to the expected term of the stock-based award. Because we do not have a sufficient history to estimate the expected term, we use the simplified method for estimating the expected term. The simplified method is based on the average of the vesting tranches and the contractual life of each grant. We estimate our expected stock volatility based on our to-date historical price volatility. We have not paid and do not anticipate paying cash dividends on our shares of Common Stock; therefore, the expected dividend yield is assumed to be zero. In 2017, the Company elected to use an actual occurrence method of recording award forfeitures rather than the prior standard of estimating forfeitures as of the grant date. We periodically issue performance-based awards. For these awards, vesting will occur upon the achievement of certain milestones. When achievement of the milestone is deemed probable, we expense the compensation of the stock award over the implicit service period. Stock awards to non-employees are accounted for in accordance with ASC 505-50, Equity-Based Payments to Non-Employees Impairment of Long-Lived Assets The Company regularly reviews the carrying amount of its long-lived assets to determine whether indicators of impairment may exist that warrant adjustments to carrying values or estimated useful lives. If indications of impairment exist, projected future undiscounted cash flows associated with the asset are compared to the carrying amount to determine whether the asset’s value is recoverable. If the carrying value of the asset exceeds such projected undiscounted cash flows, the asset will be written down to its estimated fair value. Loss Contingencies In accordance with ASC 450, Contingencies Income Taxes The Company provides for income taxes under the liability method. The Company records deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the Company’s financial reporting and the tax bases of assets and liabilities measured using the enacted tax rates expected to be in effect in the years in which the differences are expected to reverse. Deferred tax assets are reduced by a valuation allowance to reflect the uncertainty associated with their ultimate realization. The Company accounts for uncertain tax positions recognized in the consolidated financial statements by applying a more-likely-than-not threshold for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. Guarantees The Company has identified the guarantees described below as disclosable, in accordance with ASC 460, Guarantees As permitted under Delaware law, the Company indemnifies its officers and directors for certain events or occurrences while the officer or director is, or was, serving at the Company’s request in such capacity. The maximum potential amount of future payments the Company could be required to make is unlimited; however, the Company has directors’ and officers’ insurance coverage that should limit its exposure and enable it to recover a portion of any future amounts paid. The Company is a party to a number of agreements entered into in the ordinary course of business that contain typical provisions that obligate the Company to indemnify the other parties to such agreements upon the occurrence of certain events. Such indemnification obligations are usually in effect from the date of execution of the applicable agreement for a period equal to the applicable statute of limitations. The aggregate maximum potential future liability of the Company under such indemnification provisions is uncertain. For the three and six months ended June 30, 2019 and 2018, the Company had not experienced any material losses related to these indemnification obligations, and no material claims with respect thereto were outstanding. The Company does not expect significant claims related to these indemnification obligations and, consequently, concluded that the fair value of these obligations is negligible. As a result, no related reserves have been established. Issuance Costs Related to Equity and Debt The Company allocates issuance costs between the individual freestanding instruments identified on the same basis as proceeds were allocated. Issuance costs associated with the issuance of stock or equity contracts (i.e., equity-classified warrants and convertible preferred stock) are recorded as a charge against the gross proceeds of the offering. Any issuance costs associated with the issuance of liability-classified warrants are expensed as incurred. Issuance costs associated with the issuance of debt (i.e., convertible debt) is recorded as a direct reduction of the carrying amount of the debt liability but limited to the notional value of the debt. The Company accounts for debt as liabilities measured at amortized cost and amortizes the resulting debt discount to interest expense using the effective interest method over the expected term of the notes pursuant to ASC 835, Interest Embedded Conversion Features The Company evaluates embedded conversion features within convertible debt under ASC 815 “Derivatives and Hedging” to determine whether the embedded conversion feature(s) should be bifurcated from the host instrument and accounted for as a derivative at fair value with changes in fair value recorded in earnings. If the conversion feature does not require derivative treatment under ASC 815, the instrument is evaluated under ASC 470-20 “Debt with Conversion and Other Options.” Under ASC 470-20, an entity must separately account for the liability and equity components of the convertible debt instruments that may be settled entirely or partially in cash upon conversion in a manner that reflects the issuer’s economic interest cost. The effect of ASC 470-20 on the accounting for our convertible debt instruments is that the equity component is required to be included in the additional paid-in capital section of stockholders’ equity on the consolidated balance sheets and the value of the equity component is treated as original issue discount for purposes of accounting for the debt component of the notes. Therefore, we are required to record as non-cash interest expense the amortization of the discounted carrying value of the convertible debt to the face amount over the term of the convertible debt. We report higher interest expense in our financial results because ASC 470-20 requires interest to include both the current period’s amortization of the debt discount and the instrument’s coupon interest. For conventional convertible debt where the rate of conversion is below market value, the Company values and records a "beneficial conversion feature" ("BCF") and related debt discount on issuance. When the Company records a BCF, the relative fair value of the BCF is recorded as a debt discount against the face amount of the respective debt instrument (offset to additional paid in capital) and amortized to interest expense over the life of the debt. Subsequent Events The Company evaluates events occurring after the date of its consolidated balance sheet for potential recognition or disclosure in its consolidated financial statements. There have been no material subsequent events that occurred through the date the Company issued its consolidated financial statements that require disclosure in or adjustment to its consolidated financial statements. New Accounting Pronouncements In July 2018, the FASB issued ASU No. 2018-09, Codification Improvements affects a wide variety of topics, including the following: Amendments to Subtopic 220-10, Income Statement— Reporting Comprehensive Income—Overall relates to income taxes not payable in cash; Amendments to Subtopic 470-50, Debt—Modifications and Extinguishments relates to debt extinguishment and requires that the net carrying amount of extinguished fair value elected debt equals its fair value at reacquisition and related gains or losses in other comprehensive income must be included in net income upon extinguishment of the debt; Amendments to Subtopic 480-10, Distinguishing Liabilities from Equity—Overall relates to combinations of freestanding financial instruments with non-controlling interests; Amendments to Subtopic 718-740, Compensation—Stock Compensation—Income Taxes relate to recognition timing clarification for excess tax benefits or deficiencies for compensation expense; Amendments to Subtopic 805-740, Business Combinations— Income Taxes relate to allocating tax provisions to an acquired entity; Amendments to Subtopic 815-10, Derivatives and Hedging— Overall relate to accounting for offsetting derivatives; Amendments to Subtopic 820-10, Fair Value Measurement— Overall relate to the wording with respect to how transfer restrictions effect the fair value of an asset and adds explicit wording to allow entities to measure fair value on a net basis for those portfolios in which financial assets and financial liabilities and nonfinancial instruments are managed and valued together; Amendments to Subtopic 940-405, Financial Services—Brokers and Dealers—Liabilities relate to guidance about offsetting on the balance sheet; and Amendments to Subtopic 962-325, Plan Accounting—Defined Contribution Pension Plans—Investments—Other relate to plan evaluation of whether a readily determinable fair value exists to determine whether those investments may qualify for the practical expedient to measure at net asset value in accordance with Topic 820. The transition and selection of an effective date is based on the facts and circumstances of each amendment, but many of the amendments have transition guidance with effective dates for annual periods beginning after December 15, 2018, for public business entities. The Company is currently evaluating the relevance of each component and potential impact of ASU 2018-09 components on its consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820), Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement , or ASU 2018-13, which provides guidance focused on the disclosure requirements for disclosing fair value estimates, assumptions, and methodology. Requirements removed include the requirement to disclose details around amount and reasoning for level 1 to level 2 transfers, timing policies for transfer between levels, and the valuation processes for level 3 fair value measurements. Requirements modified include details regarding net asset redemption restrictions and timing related to uncertainty disclosures. Requirement added include disclosures of changes in unrealized gains and losses for recurring level 3 measurements held as of the reporting date and disclosures around the range and weighted average of significant inputs used to develop level 3 fair value measurements. These amendments are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty will be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments will be applied retrospectively to all periods presented upon their effective date. Early adoption is permitted upon issuance of this Update and an entity is permitted to early adopt any removed or modified disclosures upon issuance of this Update and delay adoption of the additional disclosures until their effective date. The Company has not elected early adoption and is currently evaluating the individual components and as these are disclosure refinements, expects no impact to its consolidated financial statements on adoption. |

Net Loss per Common Share | 3. Net Loss per Common Share Basic net loss per common share is computed by dividing net loss by the weighted-average number of common shares outstanding during the period. Potential common stock equivalents are determined using the treasury stock method. For diluted net loss per share purposes, the Company excludes stock options and other stock-based awards, including shares issued as a result of option exercises but which are subject to repurchase by the Company, whose effect would be anti-dilutive from the calculation. During the three and six months ended June 30, 2019 and 2018, common stock equivalents were excluded from the calculation of diluted net loss per common share, as their effect was anti-dilutive due to the net loss incurred. Therefore, basic and diluted net loss per share was the same in all periods presented. The following potentially dilutive securities have been excluded from the computation of diluted weighted-average shares outstanding as of June 30, 2019 and 2018, as they would be anti-dilutive: As of June 30, 2019 2018 Warrants to purchase common stock 8,277,081 1,972,976 Options to purchase common stock and other stock-based awards 1,545,719 1,668,219 Total 9,822,800 3,641,195 |

Warrants to Purchase Common Stock and CDIs On May 4, 2016, the Company entered into a consulting agreement pursuant to which a consulting firm provides strategic advisory, finance, accounting, human resources and administrative functions, including chief financial officer services, to the Company. In connection with the consulting agreement, the Company granted the consulting firm a warrant (“Consultant Warrant”) to purchase up to 28,532 shares of the Company’s common stock at an exercise price per share equal to $0.64. The Consultant Warrant is fully vested and expires on May 4, 2021. The Company has reserved 28,532 shares of common stock related to the Consultant Warrant. As of June 30, 2019, the Consultant Warrants had not been exercised. On May 30, 2018, the Company entered into a Note and Warrant Purchase agreement that included a warrant to purchase 97,222,200 CDIs (representing 1,944,444 shares of common stock). The exercise price was initially US$0.018 per CDI and the exercise price was subsequently reset to US$0.0144 when the Company issued securities at the lower price in September 2018. The warrant can be exercised with cash or as a net exercise. The warrant was immediately exercisable on issuance and expires on May 30, 2023. On March 15, 2019, the Company entered into a Note and Warrant Purchase agreement that included a form of warrant to purchase 78,984,823 CDIs (representing 1,579,696 shares of common stock).

Fair Value of Assets and Liabilities | 5. Fair Value of Assets and Liabilities The tables below present information about the Company’s assets and liabilities that are measured at fair value on a recurring basis as of June 30, 2019 and December 31, 2018 and indicates the fair value hierarchy of the valuation techniques the Company used to determine such fair value. In general, fair values determined by Level 1 inputs utilize observable inputs such as quoted prices in active markets for identical assets or liabilities. Fair values determined by Level 2 inputs utilize data points that are either directly or indirectly observable, such as quoted prices, interest rates and yield curves. Fair values determined by Level 3 inputs utilize unobservable data points in which there is little or no market data, requiring the Company to develop its own assumptions for the asset or liability. The following tables present the assets and liabilities the Company has measured at fair value on a recurring basis (in thousands): Fair Value Measurements at Reporting Date Using Quoted Prices Significant Other Significant Active Markets for Observable Unobservable Identical Assets Inputs Inputs Description June 30, 2019 (Level 1) (Level 2) (Level 3) Assets Money market funds (included in cash and cash equivalents) $ 4 $ 4 $ — $ — Total assets $ 4 $ 4 $ — $ — Liabilities Derivative liability $ 14 $ — $ — $ 14 Total liabilities $ 14 $ — $ — $ 14 Fair Value Measurements at Reporting Date Using Quoted Prices in Significant Other Significant Active Markets for Observable Unobservable Identical Assets Inputs Inputs Description December 31, 2018 (Level 1) (Level 2) (Level 3) Assets Money market funds (included in cash and cash equivalents) $ 1,097 $ 1,097 $ — $ — Total assets $ 1,097 $ 1,097 $ — $ — Liabilities Derivative liability $ 51 $ — $ — $ 51 Total liabilities $ 51 $ — $ — $ 51 The assumptions used in the Black-Scholes option pricing model to determine the fair value of the common stock warrants as of June 30, 2019, and December 31, 2018 were as follows: June 30, December 31, 2019 2018 Exercise price (A$55.00 at the then current exchange rate) $ 0.64 $ 0.64 Fair value of common stock $ 0.77 $ 0.57 Expected volatility 169.0 % 134.0 % Expected term (in years) 1.86 2.35 Risk-free interest rate 1.8 % 2.5 % Expected dividend yield 0% 0% The following table rolls forward the fair value of the Derivative Liabilities, where fair value is determined by Level 3 inputs (in thousands): Balance at December 31, 2018 $ 51 Increase in fair value of warrants upon re-measurement 1,715 Amortization of conversion rights (40 ) Fair value of warrants issued with Notes to Related Party 4,072 Reclassification of warrants to additional paid-in caputal (5,784 ) Balance at June 30, 2019 $ 14 Cash, cash equivalents, restricted cash, prepaid expenses and other current assets, right of use assets, accounts payable, accrued expenses, short-term lease liabilities and short-term debt to Crystal Amber Fund Limited, a related party, at June 30, 2019 and December 31, 2018 are carried at amounts that approximate fair value due to their short-term maturities and highly liquid nature of these instruments. The carrying value of the Company’s long-term debt to Crystal Amber Fund Limited, a related party at December 31, 2018, and long-term lease liabilities at June 30, 2019 approximates fair value based on commonly applied estimation methodologies, published market data and industry studies obtained by the Company. |

Valuation And Qualifying Accounts [Abstract] | |
Concentrations of Credit Risk and Related Valuation Accounts | 6. Concentrations of Credit Risk and Related Valuation Accounts Financial instruments that subject the Company to credit risk primarily consist of cash and cash equivalents and restricted cash. The Company maintains its cash and cash equivalent balances with high quality financial institutions, and consequently, while the balances may exceed federally insured limits, the Company believes that such funds are subject to minimal credit risk. The Company’s short-term investments potentially subject the Company to concentrations of credit risk. The Company has adopted an investment policy that limits the amounts the Company may invest in any one type of investment and requires all investments held by the Company to hold at least an A rating from a recognized credit rating agency, thereby reducing credit risk concentration. When the Company had regulatory approval to sell EndoBarrier in select markets, the Company granted unsecured credit to customers in the normal course of business. The Company made judgments as to its ability to collect outstanding receivables and provided an allowance for receivables when collection became doubtful. Provisions were made based upon a specific review of all significant outstanding invoices and the overall quality and age of those invoices not individually reviewed. Amounts determined to be uncollectible are written off against the total reserve. After regulatory approval for EndoBarrier was suspended, the Company deemed certain remaining accounts receivable uncollectible and recorded write-offs of uncollectible accounts receivable of $42 thousand in the six months ended June 30, 2018. As of June 30, 2019 and December 31, 2018, the Company had no accounts receivable and no reserves for uncollectible accounts receivable.

Notes Payable | 10. Notes Payable 2017 Convertible Note Financing On June 15, 2017, the Company entered into a Note Purchase Agreement by and between the Company, as borrower, and Crystal Amber Fund Limited, as purchaser (the “Purchaser”). Pursuant to the Note Purchase Agreement, the Company issued and sold to the Purchaser a Senior Secured Convertible Promissory Note in an aggregate original principal amount of $5.0 million (the “2017 Note”). The Purchaser is a related party for ASX purposes and is the Company’s largest stockholder. The 2017 Note accrues interest at a rate equal to 5% per annum, compounded annually, other than during the continuance of an event of default, when the 2017 Note accrues interest at a rate of 8% per annum. The entire outstanding principal balance and all unpaid accrued interest thereon was initially due on the original maturity date of December 31, 2018, but the maturity date was extended multiple times as described below. The 2017 Note is secured by a first priority security interest in substantially all tangible and intangible assets of the Company, including intellectual property (the “Collateral”). In the event of an uncured default, the Purchaser is authorized to sell, transfer, assign or otherwise deal in or with the Collateral or the proceeds thereof or any related goods securing the Collateral, as fully and effectually as if the Purchaser were the absolute owner thereof. The ASX provided the Company with a waiver to allow all asset liens (the “Security”) to be granted to the Purchaser without the normal requirement of having to obtain stockholder approval for the grant of a security to a related party of the Company (which the Purchaser is for ASX purposes). As a result of the waiver, the Security contains a provision that provides that if an event of default occurs and the Purchaser exercises its rights under the Security, neither the Purchaser nor any of its associates can acquire any legal or beneficial interest in an asset of the Company or its subsidiaries in full or partial satisfaction of the Company’s obligations under the Security, or otherwise deal with the assets of the Company or its subsidiaries, without the Company first having complied with any applicable ASX Listing Rules, including ASX Listing Rule 10.1, other than as required by law or through a receiver, or receiver or manager (or analogous person) appointed by the Purchaser exercising its power of sale under the Security and selling the assets to an unrelated third party on arm’s length commercial terms and conditions and distributing the cash proceeds to the Purchaser or any of its associates in accordance with their legal entitlements. The entire outstanding principal balance under the 2017 Note and all unpaid accrued interest thereon is convertible into CHESS Depositary Interests (“CDIs”), each representing 1/50th of a share of the Company’s common stock, (i) prior to the maturity date, at the option of the Purchaser at a conversion price calculated based on the five-day volume weighted average price of the Company’s CDIs on the ASX (“Optional Conversion Price”), or (ii) automatically upon the occurrence of an equity financing in which the Company raises at least $10 million (a “Qualified Financing”) at the price per CDI of the CDIs issued and sold in such financing. In the event that the Borrower issues additional CDIs in a subsequent equity financing at a price per CDI that is less than the then-effective Optional Conversion Price, the Purchaser has a 30-day option to convert at an adjusted conversion price reflecting, on a weighted average basis, the lower price per CDI. The number of CDIs that the Purchaser may acquire upon conversion of the 2017 Note at this adjusted conversion price is limited to the number that maintains the Purchaser’s fully-diluted ownership percentage of the Company at the same level as existed immediately preceding the applicable subsequent equity financing. In addition, upon a change of control of the Company (other than a change of control resulting from a Qualified Financing) in which the Company’s stockholders receive cash consideration, the Company is obligated to prepay all accrued and unpaid interest plus 110% of the remaining outstanding unconverted principal balance. If the consideration received for such change of control is a non-cash consideration, the Purchaser may convert the entire outstanding principal balance under the 2017 Note and all unpaid accrued interest thereon into CDIs at the abovementioned Optional Conversion Price. Other than as described above, the Company may not prepay the 2017 Note without the consent of the Purchaser. The 2017 Note Purchase Agreement contains customary events of default including a failure to perform obligations under the 2017 Note Purchase Agreement, bankruptcy, a decision by the board of directors of the Company to wind up the Company, or if the Company otherwise ceases to carry on its ongoing business operations. If a default occurs and is not cured within the applicable cure period or is not waived, any outstanding obligations under the 2017 Note may be accelerated. The 2017 Note Purchase Agreement and related 2017 Note documents also contain additional representations and warranties, covenants and conditions, in each case customary for transactions of this type. The Company recorded the $5 million 2017 Note, net of debt issuance costs of $115 thousand and amortized the debt issuance costs over the life of the 2017 Note. For the year ended December 31, 2018, the Company accrued $257 thousand of interest expense and $71 thousand in amortization of debt issuance costs related to the 2017 Note. Due to the timing of the finalization of the 2017 Note financing in 2017, the 2017 Note was issued without stockholder approval. As a consequence, while the 2017 Note contains conversion provisions, the Purchaser had, for a period of time, no right to exercise those rights until such rights of exercise were approved by the stockholders of the Company. Stockholder approval of the Purchaser’s right to convert the 2017 Note was obtained at the Company’s Annual Meeting on May 24, 2018. In December 2018, the maturity date of the 2017 Note was extended to March 31, 2019 in exchange for payment of $394 thousand which was the total interest accrued for on the 2017 Note at December 31, 2018. Payment of this amount was made in January 2019. The modification extended the conversion rights and resulted in an additional $40 thousand of debt discount liability being recorded along with issuance costs of $53 thousand. For the three and six months ended June 30, 2018, the Company recognized interest expense of $63 and $124 thousand and amortization of debt issuance costs of $19 and $37 thousand, respectively, related to the 2017 Note. In March 2019, the maturity date of the 2017 Note was extended to May 1, 2019. The modification extended the beneficial conversion rights and resulted in an additional debt discount liability, which was not recorded since it was determined to be immaterial to the consolidated financial statements. In April 2019, the maturity date of the 2017 Note was further extended to July 1, 2019, which resulted in $24 thousand of debt discount liability being recorded. In June 2019, the maturity date of the 2017 Note was further extended to October 1, 2019, which resulted in an additional $31 thousand of the debt discount liability being recorded. For the three and six months ended June 30, 2019, the Company recognized interest expense of $63 and $126 thousand related to the 2017 Note, as well as interest expense related to the additional debt discount liability of $55 thousand and $55 thousand, respectively. 2018 Convertible Note and Warrant Financing On May 30, 2018, the Company entered into a Note Purchase Agreement by and between the Company, as borrower, and Crystal Amber Fund Limited, as purchaser (the “Purchaser”). Pursuant to the Note Purchase Agreement, the Company issued and sold to the Purchaser a Senior Unsecured Convertible Promissory Note in an aggregate original principal amount of $1.75 million (the “2018 Note”) with a maturity date of May 30, 2023. Interest accrued at an annually compounded rate of 10%. The Purchaser is a related party and is the Company’s largest stockholder. The entire outstanding principal balance under the 2018 Note and all unpaid accrued interest thereon was convertible into CHESS Depositary Interests (“CDIs”), each representing 1/50th of a share of the Company’s common stock, at the option of the Purchaser at a conversion price of US$0.018 per CDI. Subsequently, the Company issued additional CDIs in a subsequent equity financing in September 2018 at a price per CDI of US$0.0144, resulting in an adjustment of the conversion price to US$0.0144 per CDI. In connection with the issuance of the 2018 Note, the Company also issued to the Purchaser a warrant (the “2018 Warrant”) to purchase 97,222,200 CDIs (representing 1,944,444 common shares) at an initial exercise price of US$0.018 per CDI, as per the 2018 Note conversion price, the warrant exercise price was subsequently adjusted to US$0.0144 per CDI, and is subject to further exercise price adjustment on certain conditions as described in the 2018 Warrant. The 2018 Warrant may be exercised at any time on a cash or cashless basis until the 2018 Warrant expires on May 30, 2023. The Company has evaluated the guidance ASC 480-10 Distinguishing Liabilities from Equity, A Contracts in an Entity's Own Equity Debt with Conversion and Other Options The Company recorded the 2018 Note at issuance, net of the total debt discount of $1.75 million and amortized the debt discount over the life of the 2018 Note. For the three and six months ended June 30, 2019, the Company accrued interest expense of $47 and $91 thousand and debt discount amortization of $74 and $146 thousand. For the three and six months ended June 30, 2018, the Company recognized interest expense of $14 thousand and debt discount amortization of $25 thousand, and interest expense derived from issuance costs of $85 thousand, respectively. The 2018 Note was converted on June 30, 2019 to 134,852,549 CDIs (representing 2,697,050 common shares). The principal of $1.75 million converted to 121,527,777 CDIs (representing 2,430,555 common shares) and the accrued interest of $192 thousand converted to 13,324,772 CDIs (representing 266,495 common shares). Upon the conversion of the 2018 Note, the Company also recorded $1.4 million of unamortized interest expense related to the unamortized debt discount. As of June 30, 2019, the conversion of the CDIs had been executed, but not yet settled with the CDIs issued and available. March 2019 Convertible Note and Warrant Financing On March 15, 2019, the Company entered into a Note Purchase Agreement by and between the Company, as borrower, and Crystal Amber Fund Limited, as purchaser (the “Purchaser”). Pursuant to the Note Purchase Agreement, the Company issued and sold to the Purchaser a Senior Unsecured Convertible Promissory Note in an aggregate original principal amount of $1 million (the “March 2019 Note”). The Purchaser is a related party and is the Company’s largest stockholder. Being a related party, certain conversion features in the March 2019 Note and the March 2019 warrant required stockholder approval, which was obtained on June 30, 2019. The March 2019 Note accrued interest at a rate equal to 10% per annum, compounded annually. The March 2019 Note was to mature on March 15, 2024. Issuance costs related to the March 2019 Note were $50 thousand. The entire outstanding principal balance under the March 2019 Note and all unpaid accrued interest thereon was convertible into CHESS Depositary Interests (“CDIs”), each representing 1/50th of a share of the Company’s common stock, at the option of the Purchaser at a conversion price of US$0.0127 per CDI. In conjunction with the issuance of the March 2019 Note, the Company issued a warrant (the “March 2019 Warrant”) to purchase 78,984,823 CDIs (representing 1,579,696 common shares) at an initial exercise price of US$0.0127 per CDI, subject to adjustment as described in the March 2019 Warrant. The March 2019 Warrant required the approval of stockholders and was recorded in derivative liability as it was not exercisable until approved on June 30, 2019. The warrant is exercisable at any time on a cash or cashless basis prior to its expiration on June 30, 2024. The March 2019 Warrant includes a price protection clause such that if the Company issues securities in a subsequent financing at a per CDI price of less than US$0.0127, the exercise price of the March 2019 Warrant will be reduced to the lowest such price per CDI (or the equivalent for shares of common stock) at which the newly issued securities were sold. The Company has evaluated the guidance ASC 480-10 Distinguishing Liabilities from Equity, A Contracts in an Entity's Own Equity Debt with Conversion and Other Options Upon approval of the conversion features and issuance of the warrants on June 30, 2019, the Company remeasured the warrant liability and recorded a $576 thousand other expense to the consolidated statement of operations and then reclassified $1,447 thousand of fair value of warrants from derivative liability to equity as approval of the warrant made the warrant immediately exercisable. The Company then evaluated the March 2019 Note for beneficial conversion feature ("BCF’). Based upon the effective conversion price of the March 2019 Note after considering the stock price at the date of stockholder approval and the allocation of estimated fair value to the March 2019 Warrant, it was determined that the March 2019 Note contained a BCF. The value of the BCF was computed to be approximately $741 thousand but has been capped at approximately $265 thousand so as to not exceed the total proceeds from the March 2019 Note after deducting the value allocated to the March 2019 Note and 2019 Warrant. The relative fair value of the warrant upon stockholder approval was approximately $735 thousand. The total debt discount on the March 2019 Note upon stockholder approval was $1M. The effective interest rate on the Note after the discounts is 29.4%. For the three and six months ended June 30, 2019, immediately prior to the Note conversion the Company recognized accrued interest expense of $25 and $29 thousand and debt discount amortized to interest expense of $52 and $60 thousand, respectively. On Note conversion, unamortized debt discount of $1 million was recorded as interest expense. The March 2019 Note principal of $1 million and accrued interest of $30 thousand were transferred to common stock subscribed but unissued. The conversion features of the March 2019 Note were approved on June 30, 2019 and on the same day, the March 2019 Note was converted to 81,070,003 CDIs (representing 1,621,400 common shares). The principal of $1 million converted to 78,740,157 CDIs (representing 1,574,803 common shares) and the accrued interest of approximately $30 thousand converted to 2,329,846 CDIs (representing 46,596 common shares). May 2019 Convertible Note and Warrant Financing On May 8, 2019, the Company entered into a Note Purchase Agreement by and between the Company, as borrower, and Crystal Amber Fund Limited, as purchaser (the “Purchaser”). Pursuant to the Note Purchase Agreement, the Company issued and sold to the Purchaser a Senior Unsecured Convertible Promissory Note in an aggregate original principal amount of $3 million (the “May 2019 Note”). The Purchaser is a related party and is the Company’s largest stockholder. Being a related party, certain conversion features in the May 2019 Note and the May 2019 warrant required stockholder approval, which was obtained on June 30, 2019. The May 2019 Note was funded in four tranches, starting on May 8, 2019 and the full $3 million funding was completed on June 28, 2018. The note accrued interest at 10% per annum, computed on the daily funded balance until completion of funding on June 28, 2019, when interest began to compound annually. The May 2019 Note was to mature on May 8, 2024. Issuance costs were $87 thousand. The entire outstanding principal balance under the May 2019 Note and all unpaid accrued interest thereon was convertible into CHESS Depositary Interests (“CDIs”), each representing 1/50th of a share of the Company’s common stock, at the option of the Purchaser at a conversion price of US$0.0127 per CDI. In conjunction with the issuance of the May 2019 note, the Company issued a warrant (the “May 2019 Warrant”) to purchase 236,220,472 CDIs (representing 4,724,409 common shares) at an initial exercise price of US$0.0127 per CDI, subject to adjustment as described in the May 2019 Warrant. The May 2019 Warrant required the approval of stockholders and was recorded in derivative liability as it was not exercisable until approved on June 30, 2019. The warrant is exercisable at any time on a cash or cashless basis, prior to its expiration on June 30, 2024. The May 2019 Warrant includes a price protection clause such that if the Company issues securities in a subsequent financing at a per CDI price of less than US$0.0127, the exercise price of the May 2019 Warrant will be reduced to the lowest such price per CDI (or the equivalent for shares of common stock) at which the newly issued securities were sold. The Company has evaluated the guidance ASC 480-10 Distinguishing Liabilities from Equity, A Contracts in an Entity's Own Equity Debt with Conversion and Other Options Upon approval of the conversion features and issuance of the warrants on June 30, 2019, the Company revalued the warrant liability and recorded a remeasurement of derivative liabilities in the amount of $1.14 million to the consolidated statements of operations and then reclassified $4,337 thousand of fair value of warrants from derivative liability to equity as approval of the warrant which made the warrant immediately exercisable. The Company then evaluated the May 2019 Note for beneficial conversion feature ("BCF’). Based upon the effective conversion price of the May 2019 Note after considering the stock price at the date of stockholder approval and the allocation of estimated fair value to the May 2019 Warrant, it was determined that the May 2019 Note contained a BCF. The value of the BCF was computed to be approximately $2.0 million but has been capped at approximately $844 thousand so as to not exceed the total proceeds from the May 2019 Note after deducting the value allocated to the May 2019 Note and May 2019 Warrant. The relative fair value of the warrant upon shareholder approval was approximately $2,136 thousand. The total debt discount on the May 2019 note upon shareholder approval was $3 million. The effective interest rate on the Note after the discounts is 29.4%. For the three and six months ended June 30, 2019, immediately prior to the Note conversion the Company recognized accrued interest expense of $19 thousand and debt discount amortized to interest expense of $180 thousand, respectively. On Note conversion, unamortized debt discount of $3 million was reclassed to interest expense. The March 2019 Note principal of $3 million and accrued interest of $19 thousand were transferred to common stock subscribed but unissued. The conversion features of the May 2019 Note were approved on June 30, 2019 and on the same day, the May 2019 Note was converted to 237,687,411 CDIs (representing 4,753,747 common shares). The principal of $3 million converted to 236,220,472 CDIs (representing 4,724,409 common shares) and the accrued interest of $19 thousand converted to 1,466,939 CDIs (representing 29,338 common shares). |

Leases [Abstract] | |
Leases | 11. Leases On January 1, 2019, the Company adopted Topic 842 using the modified retrospective approach. There was no impact to retained earnings upon adoption of Topic 842 as there were no active long-term leases in place at the adoption date. Leases with an initial term of 12 months or less are not recorded on the balance sheet, unless the arrangement includes an option to purchase the underlying asset, or an option to renew the arrangement, that we are reasonably certain to exercise (short-term leases). In June 2016, the Company entered into a non-cancelable agreement to lease approximately 4,200 square feet of office space in Boston, Massachusetts. The lease commenced in June 2016 and expired in April 2018. Rent during the term was $12 thousand per month. In December 2018, the Company entered into a 6-month membership agreement with WeWork for 985 square feet of office space located in Boston, Massachusetts. The committed lease term expired in May 2019 and contained a two-month cancellation provision. The WeWork agreement contained no explicit or guaranteed extension provisions. On April 22, 2019, the Company entered into a Right-of-Use lease for 3,520 square feet of office space in Boston, Massachusetts. The lease period contractually commenced June 1, 2019 and expires on May 31, 2022, but the space was available for occupancy on May 1, resulting in an effective period of May 2019 through May 2022, with no rent payment assessed in May 2019. The lease has defined escalating rent payments and contains no extension or expansion rights. On lease execution, the Company recorded the approximately $509 thousand present value of the lease liability in short-term and long-term liabilities and recorded a related Right of Use Asset. The Right-of-Use asset will be amortized to lease expense and the liability will be reduced by the rent payments over the term of the lease. As of June 30, 2019, the accumulated depreciation on the lease was approximately $11 thousand. Additional property tax allocations and separately metered utilities will all be expensed in the period incurred. The Company's leases generally do not provide an implicit rate and therefore the Company used 10% as an estimate of its incremental borrowing rate as the discount rate when measuring operating lease liabilities. The incremental borrowing rate represents an estimate of the interest rate the Company would incur at lease commencement to borrow an amount equal to the lease payments on a collateralized basis over the term of a lease in a similar economic environment. The Company had no leases currently classified as finance leases or previously classified as capital leases in either reporting period. The following table presents supplemental balance sheet information related to our operating lease: As of June 30, 2019 Operating Leases (in thousands) Right-of-Use Assets $ 497 Liabilities Short-term operating lease liabilities 179 Long-term operating lease liabilities 318 Total Liabilities $ 497 The total operating lease cost for short-term leases not included as lease liabilities and right of use assets on the balance sheet was $55 thousand and $92 thousand for the three-month and six-month periods ended June 30, 2019, respectively. The total operating lease cost for long-term leases included as lease liabilities and right of use assets on the balance sheet was $16 thousand for the three-month and six-month periods ended June 30, 2019.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract] | |
Share-Based Compensation | 13. Share-Based Compensation The Company has two stock-based compensation plans. In May 2003, the Board of Directors adopted the 2003 Omnibus Stock Plan (the “2003 Plan”), which provides for the grant of qualified incentive stock options and nonqualified stock options or other awards to the Company’s employees, officers, directors, advisors, and outside consultants to purchase up to an aggregate of 922,086 shares of the Company’s common stock. In August 2011, the Board of Directors adopted the 2011 Employee, Director and Consultant Equity Incentive Plan (the “2011 Plan”, together with the 2003 Plan, the “Plans”) as the successor to the 2003 Plan. Under the 2011 Plan, the Company may grant incentive stock options, nonqualified stock options, restricted and unrestricted stock awards and other stock-based awards. The Company had initially reserved 450,000 shares of its common stock for issue under the 2011 Plan. Awards that are returned to the Company’s 2003 Plan as a result of their forfeiture, expiration or cancellation without delivery of common stock shares or that result in the forfeiture of shares back to the Company on or after August 1, 2011, the date the 2011 Plan became effective, are automatically made available for issuance under the 2011 Plan. At August 1, 2011, 80,235 shares available for grant under the 2003 Plan were transferred to the 2011 Plan. At June 30, 2019, there were 1,748,812 shares available for future grant under the 2011 Plan. In addition, the 2011 Plan allows for an annual increase in the number of shares available for issue under the 2011 Plan commencing on the first day of each fiscal year during the period beginning in fiscal year 2012 and ending in fiscal year 2020. The annual increase in the number of shares shall be equal to the lowest of: a. 500,000 shares; b. 4% of the number of common shares outstanding as of such date; and c. an amount determined by the Board of Directors or the Company’s compensation committee. Accordingly, in the first quarter of fiscal 2019, 500,000 options available for future grant were added to the 2011 Plan. Stock-Based Compensation Stock-based compensation is reflected in the consolidated statements of operations as follows for the three and six months ended June 30, 2019 and 2018 (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2019 2018 2019 2018 Research and development $ 16 $ — $ 32 $ 5 Sales and marketing — 4 — 10 General and administrative 41 31 84 49 $ 57 $ 35 $ 116 $ 64 The stock options granted under the Plans generally vest over a four-year period and expire ten years from the date of grant. From time to time, the Company grants stock options to purchase common stock subject to performance-based milestones. The vesting of these stock options will occur upon the achievement of certain milestones. When achievement of the milestone is deemed probable, the Company expenses the compensation of the respective stock option over the implicit service period. In calculating stock-based compensation costs, the Company estimates the fair value of stock options using the Black-Scholes option-pricing model. The Black-Scholes option-pricing model was developed for use in estimating the fair value of short-lived, exchange-traded options that have no vesting restrictions and are fully transferable. Such costs are then recognized over the requisite service period of the awards on a straight-line basis. Determining the fair value of stock-based awards using the Black-Scholes option-pricing model requires the use of highly subjective assumptions, including the expected term of the award and expected stock price volatility. The weighted-average assumptions used to estimate the fair value of employee stock options using the Black-Scholes option-pricing model were as follows for the three and six months ended June 30, 2019 and 2018: Three Months Ended June 30, Six Months Ended June 30, 2019 2018 2019 2018 Expected volatility 126.1 % 119.4 % 126.1 % 117.1 % Expected term (in years) 6.05 6.05 6.05 6.05 Risk-free interest rate 1.8 % 2.6 % 1.8 % 2.5 % Expected dividend yield 0 % 0 % 0 % 0 % Stock Options The following table summarizes share-based activity under the Company’s stock option plans for the six months ended June 30, 2019: Shares of Common Stock Attributable to Options Weighted- Average Exercise Price Weighted- Average Contractual Life Aggregate Intrinsic Value (in years) (in thousands) Outstanding at December 31, 2018 985,224 $ 2.24 8.48 $ — Granted 235,000 $ — Exercised — $ — Cancelled — — — $ — Outstanding at June 30, 2019 1,220,224 $ 2.24 8.24 $ 1 Vested or expected to vest at June 30, 2019 1,220,224 $ 2.24 8.24 $ 1 Exercisable at June 30, 2019 486,916 $ 4.87 6.87 $ — As of June 30, 2019, there was approximately $586 thousand of unrecognized stock-based compensation related to unvested stock option grants having service-based vesting under the Plans which is expected to be recognized over a weighted-average period of 2.3 years. The intrinsic value in the table above represents the difference between the fair value of the Company’s common stock on the measurement date and the exercise price of the stock option. The stock-based compensation plans provide that grantees may have the right to exercise an option prior to vesting. Shares purchased upon the exercise of unvested options will be subject to the same vesting schedule as the underlying options and are subject to repurchase at the original exercise price by the Company should the grantee discontinue providing services to the Company for any reason, prior to becoming fully vested in such shares. Restricted Stock Units & Performance Stock Units Each restricted stock unit and performance stock unit (“RSU & PSU”) issued under the Company Plans represents a contingent right to receive one share of the Company’s common stock. The RSUs & PSUs outstanding at June 30, 2019 vest upon the achievement of certain product revenue, regulatory and reimbursement milestones. There is no consideration payable on the vesting of RSUs & PSUs issued. Upon vesting, RSUs and PSUs are exercised automatically and settled in shares of the Company’s common stock. The following table summarizes information related to RSU & PSU activity for the six months ended June 30, 2019: Number of Units Weighted- Average Contractual Life Aggregate Intrinsic Value (in years) (in thousands) Outstanding at December 31, 2018 250,000 7.23 $ 141 Granted — Exercised — Cancelled — — — Outstanding at June 30, 2019 250,000 6.98 $ 186 The aggregate intrinsic value at June 30, 2019 and December 31, 2018 noted in the table above represents the closing price of the Company’s common stock multiplied by the number of RSUs and PSUs outstanding. The fair value of each RSU and PSU award equals the closing price of the Company’s common stock on the date of grant. At June 30, 2019, all RSUs and PSUs outstanding are subject to performance-based vesting criteria as described in the applicable award agreement. For these awards, vesting will occur upon the achievement of certain product revenue, regulatory and reimbursement milestones. When achievement of the milestone is deemed probable, the Company expenses the compensation of the respective stock award over the implicit service period. At June 30, 2019 and 2018, no RSUs and PSUs that have performance-based vesting criteria are considered probable of achievement. For the three and six months ended June 30, 2019 and 2018, the Company did not recognize any stock-based compensation for RSUs and PSUs subject to performance-based vesting criteria. As of June 30, 2019, there remains approximately $283 thousand of unrecognized stock-based compensation. |

Segment Reporting [Abstract] | |
Segment Reporting | 14. Segment Reporting Operating segments are components of an enterprise for which separate financial information is available and is evaluated regularly by the Company’s chief operating decision-maker in deciding how to allocate resources and in assessing performance. The Company has one reportable segment which designs, develops, manufactures and markets medical devices for non-surgical approaches to treating type 2 diabetes and obesity. Geographic Reporting The Company has historically reported various geographic segments, but at June 30, 2019, the right-of-use-asset of approximately $487 thousand and all long-lived assets, comprised of property and equipment, of approximately $51 thousand are all held in the U.S. and the Company did not have revenue for the three and six months ended June 30, 2019 and 2018, respectively. Major Customers The Company did not recognize any revenue for the three and six months ended June 30, 2019 and 2018, respectively. |
Summary of Significant Accoun_2
Summary of Significant Accounting Policies and Basis of Presentation (Policies) | 6 Months Ended |
Jun. 30, 2019 | |
Accounting Policies [Abstract] | |
Principles of Consolidation | Principles of Consolidation The accompanying consolidated financial statements include the accounts of GI Dynamics, Inc. and its wholly owned subsidiaries. All intercompany transactions and balances are eliminated in consolidation. |
Use of Estimates | Use of Estimates The preparation of consolidated financial statements in accordance with GAAP requires the Company’s management to make estimates and judgments that may affect the reported amounts of assets, liabilities, revenues and expenses, and the related disclosure of contingent assets and liabilities. On an ongoing basis, the Company’s management evaluates its estimates, including those related to impairment of long-lived assets, income taxes including the valuation allowance for deferred tax assets, research and development, contingencies, lease liabilities, valuation of derivative liabilities, estimates used to assess its ability to continue as a going concern and stock-based compensation. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ from these estimates under different assumptions or conditions. Changes in estimates are reflected in reported results in the period in which they become known. |
Cash and Cash Equivalents | Cash and Cash Equivalents The Company considers all highly liquid investment instruments with an original maturity when purchased of three months or less to be cash equivalents. Investments qualifying as cash equivalents primarily consist of money market funds and have a carrying amount that approximates fair value. The amount of cash equivalents included in cash and cash equivalents was approximately $4 thousand The Company has $30 thousand in restricted cash used to secure a corporate credit card account. |
Inventory | Inventory When the Company resumes commercial activity, the Company will state inventory at the lower of first-in, first-out cost or net realizable value. When capitalizing inventory, the Company will consider factors such as status of regulatory approval, alternative use of inventory, and anticipated commercial use of the product. At June 30, 2019 and December 31, 2018, there was no inventory or reserves against inventory on the balance sheet. |
Property and Equipment | Property and Equipment Property and equipment, including leasehold improvements, are recorded at cost and are depreciated when placed in service using the straight-line method based on their estimated useful lives. Included in property and equipment are certain costs of software obtained for internal use. Costs incurred during the preliminary project stage are expensed as incurred, while costs incurred during the application development stage are capitalized and amortized over the estimated useful life of the software. The Company also capitalizes costs related to specific upgrades and enhancements when it is probable the expenditures will result in additional functionality. Maintenance and training costs related to software obtained for internal use are expensed as incurred. Leasehold improvements are amortized over the shorter of the estimated useful life of the asset or the remaining lease term. Costs for capital assets not yet placed into service are capitalized as construction in progress and will be subsequently depreciated in accordance with the above guidelines once placed into service. Maintenance and repair costs are expensed as incurred. |
Lease Liabilities and Related Assets | Lease Liabilities and Related Assets The Company adopted Accounting Standards Codification (“ASC”), Topic 842, Leases Leases At the inception of an arrangement, the Company determines whether the arrangement is or contains a lease based on the unique facts and circumstances present. The Company has elected not to recognize on the balance sheet leases with terms of one year or less. Leases with a non-cancellable term greater than one year are recognized on the balance sheet as lease assets, short-term lease liabilities and long-term lease liabilities. Using criteria defined in ASC 842, the Company determines whether the lease is a Financing Lease or an Operating Lease. Lease liabilities and their corresponding Right-of-Use assets are recorded based on the present value of lease payments over the expected remaining lease term. Options to renew an Operating lease are not included in the Company’s initial lease term assessment unless there is reasonable certainty that the Company will renew. However, certain adjustments to the Right-of-Use operating asset may be required for items such as incentives received. The interest rate implicit in lease contracts is typically not readily determinable. As a result, the Company utilizes an estimated incremental borrowing rate, which is the rate it is expected to incur to borrow an amount equal to the lease payments on a collateralized basis (or on an unsecured basis if existing debt covenants prevent further securitization) over a similar term in a similar economic environment. In accordance with the guidance in ASC 842, components of a lease are split into lease components and non-lease components. A policy election is available pursuant to which an entity may elect to not separate lease and non-lease components. For new and amended leases beginning in 2019 and after, the Company has not made the election to combine lease and non-lease components. |
Research and Development Costs | Research and Development Costs Research and development costs are expensed when incurred. Research and development costs include costs of all basic research activities as well as other research, engineering, and technical effort required to develop a new product or service or make significant improvement to an existing product or manufacturing process. Research and development costs also include preapproval regulatory and clinical trial expenses incurred prior to regulatory approval. |
Patent Costs | Patent Costs The Company expenses as incurred all costs, including legal expenses, associated with obtaining patents until the patented technology becomes feasible. All costs incurred after the patented technology is feasible will be capitalized as an intangible asset. As of June 30, 2019 and December 31, 2018, no such costs had been capitalized. The Company expensed patent costs within general and administrative expenses of $54 and $41 thousand for the three months ended June 30, 2019 and 2018, respectively, and $95 and $80 thousand for the six months ended June 30, 2019 and 2018, respectively. |
Stock-Based Compensation | Stock-Based Compensation We account for stock-based compensation in accordance with the Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC, 718, Stock Compensation For awards that vest based on service conditions, we use the straight-line method to allocate compensation expense to reporting periods. The grant date fair value of options granted is calculated using the Black-Scholes option pricing model, which requires the use of subjective assumptions including volatility, expected term and the fair value of the underlying Common Stock, among others. The assumptions used in determining the fair value of stock-based awards represent management’s best estimates, but these estimates involve inherent uncertainties and the application of management judgment. As a result, if factors change, and we use different assumptions, our stock-based compensation could be materially different in the future. The risk-free interest rate used for each grant is based on a zero-coupon U.S. Treasury instrument with a remaining term similar to the expected term of the stock-based award. Because we do not have a sufficient history to estimate the expected term, we use the simplified method for estimating the expected term. The simplified method is based on the average of the vesting tranches and the contractual life of each grant. We estimate our expected stock volatility based on our to-date historical price volatility. We have not paid and do not anticipate paying cash dividends on our shares of Common Stock; therefore, the expected dividend yield is assumed to be zero. In 2017, the Company elected to use an actual occurrence method of recording award forfeitures rather than the prior standard of estimating forfeitures as of the grant date. We periodically issue performance-based awards. For these awards, vesting will occur upon the achievement of certain milestones. When achievement of the milestone is deemed probable, we expense the compensation of the stock award over the implicit service period. Stock awards to non-employees are accounted for in accordance with ASC 505-50, Equity-Based Payments to Non-Employees |
Impairment of Long-Lived Assets | Impairment of Long-Lived Assets The Company regularly reviews the carrying amount of its long-lived assets to determine whether indicators of impairment may exist that warrant adjustments to carrying values or estimated useful lives. If indications of impairment exist, projected future undiscounted cash flows associated with the asset are compared to the carrying amount to determine whether the asset’s value is recoverable. If the carrying value of the asset exceeds such projected undiscounted cash flows, the asset will be written down to its estimated fair value. |
Loss Contingencies | Loss Contingencies In accordance with ASC 450, Contingencies |
Income Taxes | Income Taxes The Company provides for income taxes under the liability method. The Company records deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the Company’s financial reporting and the tax bases of assets and liabilities measured using the enacted tax rates expected to be in effect in the years in which the differences are expected to reverse. Deferred tax assets are reduced by a valuation allowance to reflect the uncertainty associated with their ultimate realization. The Company accounts for uncertain tax positions recognized in the consolidated financial statements by applying a more-likely-than-not threshold for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. |
Guarantees | Guarantees The Company has identified the guarantees described below as disclosable, in accordance with ASC 460, Guarantees As permitted under Delaware law, the Company indemnifies its officers and directors for certain events or occurrences while the officer or director is, or was, serving at the Company’s request in such capacity. The maximum potential amount of future payments the Company could be required to make is unlimited; however, the Company has directors’ and officers’ insurance coverage that should limit its exposure and enable it to recover a portion of any future amounts paid. The Company is a party to a number of agreements entered into in the ordinary course of business that contain typical provisions that obligate the Company to indemnify the other parties to such agreements upon the occurrence of certain events. Such indemnification obligations are usually in effect from the date of execution of the applicable agreement for a period equal to the applicable statute of limitations. The aggregate maximum potential future liability of the Company under such indemnification provisions is uncertain. For the three and six months ended June 30, 2019 and 2018, the Company had not experienced any material losses related to these indemnification obligations, and no material claims with respect thereto were outstanding. The Company does not expect significant claims related to these indemnification obligations and, consequently, concluded that the fair value of these obligations is negligible. As a result, no related reserves have been established. |
Issuance Costs Related to Equity and Debt | Issuance Costs Related to Equity and Debt The Company allocates issuance costs between the individual freestanding instruments identified on the same basis as proceeds were allocated. Issuance costs associated with the issuance of stock or equity contracts (i.e., equity-classified warrants and convertible preferred stock) are recorded as a charge against the gross proceeds of the offering. Any issuance costs associated with the issuance of liability-classified warrants are expensed as incurred. Issuance costs associated with the issuance of debt (i.e., convertible debt) is recorded as a direct reduction of the carrying amount of the debt liability but limited to the notional value of the debt. The Company accounts for debt as liabilities measured at amortized cost and amortizes the resulting debt discount to interest expense using the effective interest method over the expected term of the notes pursuant to ASC 835, Interest |
Embedded Conversion Features | Embedded Conversion Features The Company evaluates embedded conversion features within convertible debt under ASC 815 “Derivatives and Hedging” to determine whether the embedded conversion feature(s) should be bifurcated from the host instrument and accounted for as a derivative at fair value with changes in fair value recorded in earnings. If the conversion feature does not require derivative treatment under ASC 815, the instrument is evaluated under ASC 470-20 “Debt with Conversion and Other Options.” Under ASC 470-20, an entity must separately account for the liability and equity components of the convertible debt instruments that may be settled entirely or partially in cash upon conversion in a manner that reflects the issuer’s economic interest cost. The effect of ASC 470-20 on the accounting for our convertible debt instruments is that the equity component is required to be included in the additional paid-in capital section of stockholders’ equity on the consolidated balance sheets and the value of the equity component is treated as original issue discount for purposes of accounting for the debt component of the notes. Therefore, we are required to record as non-cash interest expense the amortization of the discounted carrying value of the convertible debt to the face amount over the term of the convertible debt. We report higher interest expense in our financial results because ASC 470-20 requires interest to include both the current period’s amortization of the debt discount and the instrument’s coupon interest. For conventional convertible debt where the rate of conversion is below market value, the Company values and records a "beneficial conversion feature" ("BCF") and related debt discount on issuance. When the Company records a BCF, the relative fair value of the BCF is recorded as a debt discount against the face amount of the respective debt instrument (offset to additional paid in capital) and amortized to interest expense over the life of the debt. |
Subsequent Events | Subsequent Events The Company evaluates events occurring after the date of its consolidated balance sheet for potential recognition or disclosure in its consolidated financial statements. There have been no material subsequent events that occurred through the date the Company issued its consolidated financial statements that require disclosure in or adjustment to its consolidated financial statements. |
New Accounting Pronouncements | New Accounting Pronouncements In July 2018, the FASB issued ASU No. 2018-09, Codification Improvements affects a wide variety of topics, including the following: Amendments to Subtopic 220-10, Income Statement— Reporting Comprehensive Income—Overall relates to income taxes not payable in cash; Amendments to Subtopic 470-50, Debt—Modifications and Extinguishments relates to debt extinguishment and requires that the net carrying amount of extinguished fair value elected debt equals its fair value at reacquisition and related gains or losses in other comprehensive income must be included in net income upon extinguishment of the debt; Amendments to Subtopic 480-10, Distinguishing Liabilities from Equity—Overall relates to combinations of freestanding financial instruments with non-controlling interests; Amendments to Subtopic 718-740, Compensation—Stock Compensation—Income Taxes relate to recognition timing clarification for excess tax benefits or deficiencies for compensation expense; Amendments to Subtopic 805-740, Business Combinations— Income Taxes relate to allocating tax provisions to an acquired entity; Amendments to Subtopic 815-10, Derivatives and Hedging— Overall relate to accounting for offsetting derivatives; Amendments to Subtopic 820-10, Fair Value Measurement— Overall relate to the wording with respect to how transfer restrictions effect the fair value of an asset and adds explicit wording to allow entities to measure fair value on a net basis for those portfolios in which financial assets and financial liabilities and nonfinancial instruments are managed and valued together; Amendments to Subtopic 940-405, Financial Services—Brokers and Dealers—Liabilities relate to guidance about offsetting on the balance sheet; and Amendments to Subtopic 962-325, Plan Accounting—Defined Contribution Pension Plans—Investments—Other relate to plan evaluation of whether a readily determinable fair value exists to determine whether those investments may qualify for the practical expedient to measure at net asset value in accordance with Topic 820. The transition and selection of an effective date is based on the facts and circumstances of each amendment, but many of the amendments have transition guidance with effective dates for annual periods beginning after December 15, 2018, for public business entities. The Company is currently evaluating the relevance of each component and potential impact of ASU 2018-09 components on its consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820), Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement , or ASU 2018-13, which provides guidance focused on the disclosure requirements for disclosing fair value estimates, assumptions, and methodology. Requirements removed include the requirement to disclose details around amount and reasoning for level 1 to level 2 transfers, timing policies for transfer between levels, and the valuation processes for level 3 fair value measurements. Requirements modified include details regarding net asset redemption restrictions and timing related to uncertainty disclosures. Requirement added include disclosures of changes in unrealized gains and losses for recurring level 3 measurements held as of the reporting date and disclosures around the range and weighted average of significant inputs used to develop level 3 fair value measurements. These amendments are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty will be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments will be applied retrospectively to all periods presented upon their effective date. Early adoption is permitted upon issuance of this Update and an entity is permitted to early adopt any removed or modified disclosures upon issuance of this Update and delay adoption of the additional disclosures until their effective date. The Company has not elected early adoption and is currently evaluating the individual components and as these are disclosure refinements, expects no impact to its consolidated financial statements on adoption. |
