Description of Business and Summary of Significant Accounting Policies [Abstract] | |
Description of Business and Summary of Significant Accounting Policies | 1. DESC RIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of the Business —The “Company” or “AtriCure” consists of AtriCure, Inc. and its wholly-owned subsidiaries. The Company is a leading innovator in treatments for atrial fibrillation (Afib) and left atrial appendage (LAA) management and sells its products to medical centers globally through its direct sales force and distributors. Basis of Presentation —The accompanying interim financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (SEC). The accompanying interim financial statements are unaudited, but in the opinion of the Company’s management, contain all normal, recurring adjustments considered necessary to present fairly the financial position, results of operations and cash flows for the periods presented in conformity with accounting principles generally accepted in the United States of America (GAAP) applicable to interim periods. Certain information and footnote disclosures included in annual financial statements prepared in accordance with GAAP have been omitted or condensed. The Company believes the disclosures herein are adequate to make the information presented not misleading. Results of operations are not necessarily indicative of the results expected for the full year or for any future period. The accompanying Condensed Consolidated Financial Statements should be read in conjunction with the Company’s audited financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 filed with the SEC. All intercompany accounts and transactions have been eliminated in consolidation. Cash and Cash Equivalents —The Company considers highly liquid investments with maturities of three months or less at the date of purchase as cash equivalents. Cash equivalents include demand deposits, money market funds and repurchase agreements on deposit with financial institutions. Investments —The Company invests primarily in government and agency obligations, corporate bonds, commercial paper and asset-backed securities and classifies all investments as available-for-sale. Investments maturing in less than one year are classified as short-term investments. Investments are recorded at fair value, with unrealized gains and losses recorded as accumulated other comprehensive income (loss). Gains and losses are recognized using the specific identification method when securities are sold and are included in interest income. Revenue Recognition— The Company recognizes revenue when control of promised goods is transferred to customers in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods. This generally occurs upon shipment of goods to customers. See Note 8 for further discussion on revenue. Sales Returns and Allowances —The Company maintains a provision for potential returns of defective or damaged products and invoice adjustments. The Company adjusts the provision using the expected value method based on historical experience. Increases to the provision reduce revenue, and the provision is included in accrued liabilities. Allowance for Credit Losses on Accounts Receivable —The Company evaluates the expected credit losses of accounts receivable, considering historical credit losses, current customer-specific information and other relevant factors when determining the allowance. An increase to the allowance for credit losses results in a corresponding increase in selling, general and administrative expenses. The Company charges off uncollectible receivables against the allowance when all attempts to collect the receivable have failed. The Company’s history of write-offs has not been significant. Inventories —Inventories are stated at the lower of cost or net realizable value based on the first-in, first-out cost method (FIFO) and consist of raw materials, work in process and finished goods. The Company’s industry is characterized by rapid product development and frequent new product introductions. Uncertain timing of regulatory approvals, variability in product launch strategies and variation in product use all impact inventory reserves for excess, obsolete and expired products. An increase to inventory reserves results in a corresponding increase in cost of revenue. Inventories are written off against the reserve when they are physically disposed. Inventories consist of the following: June 30, December 31, 2021 2020 Raw materials $ 12,381 $ 11,966 Work in process 3,599 2,424 Finished goods 21,628 20,636 Inventories $ 37,608 $ 35,026 Property and Equipment —Property and equipment is stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of assets. The estimated useful life by major asset category is the following: Estimated Useful Life Generators and related equipment 1-3 years Building and building under finance lease 15 - 20 years Computers, software and office equipment 3 years Machinery and equipment 3 - 7 years Furniture and fixtures 3 - 7 years Leasehold improvements 5 - 15 years Equipment under finance leases 3 - 5 years The Company assesses the useful lives of property and equipment at least annually and retires assets no longer in use. Maintenance and repair costs are expensed as incurred. The Company reviews property and equipment for impairment at least annually using its best estimates based on reasonable and supportable assumptions and expected future cash flows. Property and equipment impairments have not been significant. The Company’s radiofrequency (RF) and cryo generators are generally placed with customers that use the Company’s disposable products. The estimated useful lives of generators are based on anticipated usage by customers and may change in future periods with changes in usage or introduction of new technology. Depreciation of generators and related equipment, which is included in cost of revenue, was $ 601 and $ 635 for the three months ended June 30, 2021 and 2020 and $ 1,203 and $ 1,285 for the six months ended June 30, 2021 and 2020. As of June 30, 2021 and December 31, 2020, the net carrying value of generators and related equipment included in net property and equipment was $ 3,542 and $ 3,410 . Leases — The Company leases office, manufacturing and warehouse facilities and computer equipment under leases that qualify as either financing or operating leases, as determined at the inception of the lease arrangement. Lease assets represent the right to use an underlying asset for the lease term, and lease liabilities represent the obligation to make lease payments arising from the lease. Lease assets and liabilities are measured and recorded at the commencement date based on the present value of lease payments over the lease term. Lease assets and liabilities exclude lease incentives and include options to extend or terminate when it is reasonably certain the Company will exercise that option. The Company uses the implicit rate when readily determinable; however, most of the leases do not provide an implicit rate and therefore, the Company uses the incremental borrowing rate based on the information available at measurement. The Company applies the short-term lease recognition exemption, recognizing lease payments in profit or loss, for leases that have a lease term of 12 months or less at commencement and do not include an option to extend the lease whose exercise is reasonably certain. For real estate and equipment leases, the Company accounts for the lease and non-lease components as a single lease component. Additionally, the portfolio approach is applied for the operating leases based on the terms of the underlying leases. Operating leases are included in operating lease right-of-use (ROU) assets and operating lease liabilities, while finance leases are included in property and equipment and finance lease liabilities. The short-term portions of both lease liabilities are included in other current liabilities and current maturities of debt and leases. Operating lease expense is recognized on a straight-line basis over the lease term. See Note 6 for further discussion. Intangible Assets —Intangible assets with determinable useful lives are amortized on a straight-line basis over the estimated periods benefited. Intangible assets include In Process Research and Development (IPR&D), representing the value of technology acquired in business combinations that has not yet reached technological feasibility. The primary basis for determining technological feasibility is obtaining specific regulatory approvals. IPR&D is accounted for as an indefinite-lived intangible asset until completion or abandonment of the IPR&D project. Upon completion of the development project, IPR&D will be amortized over its estimated useful life. If the IPR&D project is abandoned or regulatory approvals are not obtained, the Company may have a full or partial impairment charge related to the IPR&D, calculated as the excess carrying value of the IPR&D asset over the estimated fair value. As of June 30, 2021, the IPR&D asset represents an estimate of the fair value of the pre-market approval (PMA) that could result from the aMAZE™ IDE clinical trial. See Note 12 for further discussion. Through April 2021, the IPR&D asset also included an estimate of the fair value of the PMA that could result from the CONVERGE IDE clinical trial. The Company received PMA approval for CONVERGE on April 28, 2021 and began amortizing the technology asset over an estimated fifteen year life. The Company reviews intangible assets at least annually for impairment using its best estimates based on reasonable and supportable assumptions and projections. The Company performs impairment testing annually on October 1 or more often if impairment indicators are present. Goodwill— Goodwill represents the excess of purchase price over the fair value of the net assets acquired in business combinations. The Company’s goodwill is accounted for in a single reporting unit representing the Company as a whole. The Company performs impairment testing annually on October 1 or more often if impairment indicators are present. Contingent Consideration and Other Noncurrent Liabilities— This balance consists of contingent consideration from business combinations, as well as deferred payroll taxes as a result of the Coronavirus Aid, Relief, and Economic Security Act (CARES Act), asset retirement obligations and other contractual obligations. The contingent consideration balance is included in noncurrent liabilities as settlement is expected to be made primarily in shares of the Company’s common stock pursuant to the SentreHEART, Inc. (SentreHEART) merger agreement. Other Income (Expense) — Other income (expense) consists primarily of foreign currency transaction gains and losses generated by settlements of intercompany balances denominated in Euros and customer invoices transacted in British Pounds. Taxes —Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred income tax assets and liabilities from a change in tax rates is recognized in the period that includes the enactment date. The Company’s estimate of the valuation allowance for deferred income tax assets requires significant estimates and judgments about future operating results. Deferred income tax assets are reduced by valuation allowances if, based on the consideration of all available evidence, it is more-likely-than-not that the deferred income tax asset will not be realized. Significant weight is given to evidence that can be objectively verified. The Company evaluates deferred income tax assets on an annual basis to determine if valuation allowances are required. Deferred income tax assets are realized by having sufficient future taxable income to allow the related tax benefits to reduce taxes otherwise payable. The sources of taxable income that may be available to realize the benefit of deferred income tax assets are future taxable income, future reversals of existing taxable temporary differences, carryforwards and tax planning strategies that are both prudent and feasible. In evaluating the need for a valuation allowance, the existence of cumulative losses in recent years is significant objectively verifiable negative evidence that must be overcome by objectively verifiable positive evidence to avoid the need to record a valuation allowance. The Company has recorded a full valuation allowance against substantially all net deferred income tax assets as it is more-likely-than-not that the benefit of the deferred income tax assets will not be recognized in future periods. The Company has not reclassified income tax effects of the Tax Cuts and Jobs Act within accumulated other comprehensive income (loss) to retained earnings due to its full valuation allowance. Net Loss Per Share —Basic and diluted net loss per share is computed by dividing the net loss by the weighted average number of common shares outstanding during the period. Since the Company has experienced net losses for all periods presented, net loss per share excludes the effect of stock options, restricted stock shares, restricted stock units and performance award shares totaling 1,807 and 2,770 as of June 30, 2021 and 2020 because they are anti-dilutive. Therefore, the number of shares calculated for basic net loss per share is also used for the diluted net loss per share calculation. Comprehensive Loss and Accumulated Other Comprehensive Income (Loss) —In addition to net losses, the comprehensive loss includes foreign currency translation adjustments and unrealized gains (losses) on investments. Accumulated other comprehensive income (loss) consisted of the following, net of tax: Three Months Ended Six Months Ended June 30, June 30, 2021 2020 2021 2020 Total accumulated other comprehensive income (loss) at beginning of period $ ( 18 ) $ ( 371 ) $ 312 $ ( 158 ) Unrealized Gains (Losses) on Investments Balance at beginning of period $ 23 $ 37 $ 54 $ 100 Other comprehensive (loss) income before reclassifications ( 132 ) 174 ( 163 ) 92 Amounts reclassified from accumulated other comprehensive income to other income (expense) — — — 19 Balance at end of period $ ( 109 ) $ 211 $ ( 109 ) $ 211 Foreign Currency Translation Adjustment Balance at beginning of period $ ( 41 ) $ ( 408 ) $ 258 $ ( 258 ) Other comprehensive income (loss) before reclassifications 36 109 ( 262 ) ( 113 ) Amounts reclassified from accumulated other comprehensive income (loss) to other income (expense) 27 ( 8 ) 26 64 Balance at end of period $ 22 $ ( 307 ) $ 22 $ ( 307 ) Total accumulated other comprehensive loss at end of period $ ( 87 ) $ ( 96 ) $ ( 87 ) $ ( 96 ) Research and Development Costs —Research and development costs are expensed as incurred. These costs include compensation and other internal and external costs associated with the development of and research related to new and existing products or concepts, preclinical studies, clinical trials and related regulatory activities, as well as amortization of technology assets. Advertising Costs — The Company expenses advertising costs as incurred. Advertising costs were not significant during the three and six months ended June 30, 2021 and 2020. Share-Based Compensation —The Company records share-based compensation for all share-based payment awards, including stock options, restricted stock awards, restricted stock units, performance shares (PSAs) and stock purchases related to an employee stock purchase plan, based on estimated fair values. The value of the portion of an award that is ultimately expected to vest, net of estimated forfeitures, is recognized as expense over the service period. The Company estimates forfeitures at the time of grant and revises them, as necessary, in subsequent periods as actual forfeitures differ from those estimates. The Company recognized share-based compensation expense of $ 7,141 and $ 6,193 for the three months ended June 30, 2021 and 2020 and $ 13,745 and $ 10,577 for the six months ended June 30, 2021 and 2020. The Company estimates the fair value of time-based options on the date of grant using the Black-Scholes option-pricing model (Black-Scholes model). The Company’s determination of the fair value is affected by the Company’s stock price, as well as assumptions regarding several subjective variables. These variables include, but are not limited to, the Company’s expected stock price volatility over the term of the awards and actual and projected employee stock option exercise behaviors. The Company estimates the fair value of restricted stock awards and restricted stock units based upon the grant date closing market price of the Company’s common stock. The Company estimates the fair value of PSAs with a performance condition based on the closing stock price on the date of grant assuming the performance goal will be achieved and may adjust expense over the performance period based on changes to estimates of performance target achievement. If such goals are not met or service is not rendered for the requisite service period, no compensation cost is recognized, and any recognized compensation cost will be reversed. For PSAs with a market condition, a Monte Carlo simulation is performed to estimate the fair value on the date of grant, and compensation cost is recognized over the requisite service period as the employee renders service, even if the market condition is not satisfied. The Company’s determination of the fair value is affected by the Company and the peer group’s stock price, as defined by the award agreement, at the beginning of the service period and grant date, the expected volatility of the Company and peer group’s stock price over the performance period and the correlation coefficient of the daily returns for the Company and peer group over the performance period. The Company also has an employee stock purchase plan (ESPP) which is available to all eligible employees as defined by the plan document. Under the ESPP, shares of the Company’s common stock may be purchased at a discount. The Company estimates the number of shares to be purchased under the ESPP at the beginning of each purchase period based upon the fair value of the stock at the beginning of the purchase period using the Black-Scholes model and records estimated compensation expense during the purchase period. Expense is adjusted at the time of stock purchase. Use of Estimates —The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, including intangible assets, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expense during the reporting period. Estimates are based on historical experience, where applicable, and other assumptions believed to be reasonable by management. Actual results could differ from those estimates. |

Fair Value [Abstract] | |
Fair Value | 2. FAIR VALUE The Financial Accounting Standards Board’s (FASB) Accounting Standards Codification (ASC) 820, “Fair Value Measurements and Disclosures” (ASC 820), defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy is based on three-levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value: Level 1—Quoted prices in active markets for identical assets or liabilities. Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The Company classifies cash and investments in government and agency obligations, accounts receivable, short-term other assets, accounts payable and accrued liabilities as Level 1 within the fair value hierarchy. The carrying amounts of these assets and liabilities approximate their fair value due to their relatively short-term nature. Cash equivalents and investments in corporate bonds, commercial paper and asset-backed securities are classified as Level 2 within the fair value hierarchy. The fair value of fixed term debt is estimated by calculating the net present value of future debt payments at current market interest rates and is classified as Level 2. The book value of the Company’s fixed term debt approximates its fair value because the interest rate varies with market rates. The following table represents the Company’s fair value hierarchy for its financial assets and liabilities measured at fair value on a recurring basis as of June 30, 2021: Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Other Unobservable Inputs (Level 3) Total Assets: Money market funds $ — $ 64,732 $ — $ 64,732 Commercial paper — 17,985 — 17,985 Government and agency obligations 20,023 — — 20,023 Corporate bonds — 94,674 — 94,674 Asset-backed securities — 29,334 — 29,334 Total assets $ 20,023 $ 206,725 $ — $ 226,748 Liabilities: Contingent consideration — — 189,900 189,900 Total liabilities $ — $ — $ 189,900 $ 189,900 There were no changes in the levels or methodology of measurement of financial assets and liabilities during the three and six months ended June 30, 2021. The following table represents the Company’s fair value hierarchy for its financial assets and liabilities measured at fair value on a recurring basis as of December 31, 2020: Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Other Unobservable Inputs (Level 3) Total Assets: Money market funds $ — $ 38,452 $ — $ 38,452 Commercial paper — 76,914 — 76,914 Government and agency obligations 45,399 — — 45,399 Corporate bonds — 73,730 — 73,730 Asset-backed securities — 20,409 — 20,409 Total assets $ 45,399 $ 209,505 $ — $ 254,904 Liabilities: Contingent consideration $ — $ — $ 184,800 184,800 Total liabilities $ — $ — $ 184,800 $ 184,800 Contingent Consideration. The Company’s contingent consideration arrangements arising from the SentreHEART acquisition obligate the Company to pay certain defined amounts to former shareholders of SentreHEART if specified milestones are met related to the aMAZE IDE clinical trial, including PMA approval and reimbursement for the therapy involving SentreHEART’s devices. See Note 12 for further discussion. As of December 31, 2020, the terms of the contingent consideration arrangements under the nContact merger agreement expired. The Company measures contingent consideration liabilities using unobservable inputs by applying the probability-weighted scenario method, an income approach. Various key assumptions, such as the probability and timing of achievement of the agreed milestones, are significant to the determination of fair value of contingent consideration arrangements and are not observable in the market, thus representing a Level 3 measurement within the fair value hierarchy. The recurring Level 3 fair value measurements of the contingent consideration liabilities include the following significant inputs as of June 30, 2021: Weighted average Fair Value Valuation Technique Input Range by relative fair value Probability of payment 70.00 - 85.00 % 80.62 % Regulatory & Reimbursement milestones $ 189,900 Probability-weighted scenario approach Projected year of payment 2022 - 2025 n/a Discount rate 5.56 % 5.56 % Contingent consideration liabilities are periodically measured, with changes in the estimated fair value reflected in selling, general and administrative expenses. Changes in the discount rate, projected time until payment and probability of payment may result in materially different fair value measurements. A decrease in the discount rate would result in a higher fair value measurement, while a decrease in the probability of payment would result in a lower fair value measurement. Movement in the forecasted timing of achievement to later in the milestone periods would cause a decrease in the fair value measurement. The fair value of the SentreHEART contingent consideration was remeasured as of June 30, 2021 resulting in an increase in fair value due to accretion. The following table represents the Company’s Level 3 fair value measurements using significant other unobservable inputs for acquisition-related contingent consideration: Six Months Ended Twelve Months Ended June 30, 2021 December 31, 2020 Beginning Balance $ 184,800 $ 185,157 Amounts acquired — — Changes in fair value included in earnings 5,100 ( 357 ) Ending Balance $ 189,900 $ 184,800 |

Indebtedness [Abstract] | |
Indebtedness | 5. INDEBTEDNESS Credit Facility. The Company has a Loan and Security Agreement (Loan Agreement) with Silicon Valley Bank (SVB), which includes a $ 60,000 term loan and a $ 20,000 revolving line of credit. The total combined term loan and revolving line of credit outstanding under the Loan Agreement cannot exceed $ 70,000 at any time prior to SVB’s consent. The term loan and revolving credit facility both mature or expire, as applicable, on August 1, 2024 . On February 8, 2021, the Company and SVB entered into an amendment to the Loan Agreement which modified conditions which allow the Company to defer the term loan principal payments an additional six months , commencing in September 2021. Additionally, the covenant reporting requirements were modified. The amendment was treated as a debt modification. Term loan principal payments commence September 1, 2021. The term loan accrues interest at the greater of the Prime Rate or 5.00 %, plus 0.75 % and is subject to an additional 3.00 % fee on the $ 60,000 term loan principal payable at maturity or upon acceleration or prepayment of the term loan. The Company is accruing the 3.00 % fee over the term of the Loan Agreement, with $ 675 accrued in the outstanding loan balance as of June 30, 2021. Additionally, the unamortized original financing costs related to the term loan of $ 339 are netted against the outstanding loan balance in the Condensed Consolidated Balance Sheets and are amortized ratably over the term of the Loan Agreement. The revolving line of credit is subject to an annual facility fee of 0.15 % of the revolving line of credit, and any borrowings thereunder bear interest at the greater of the Prime Rate or 5.00 %. Borrowing availability under the revolving credit facility is based on the lesser of $ 20,000 or a borrowing base calculation as defined by the Loan Agreement. As of June 30, 2021, the Company had no borrowings under the revolving credit facility and had borrowing availability of $ 8,750 . Financing costs related to the revolving line of credit are included in other assets in the Condensed Consolidated Balance Sheets and amortized ratably over the twelve-month period of the annual fee. The Loan Agreement also provides for certain prepayment and early termination fees, as well as establishes a minimum liquidity covenant and dividend restrictions, along with other customary terms and conditions. Specified assets have been pledged as collateral. Future maturities of long-term debt, excluding the term loan final fee, are projected as follows: 2021 (excluding the six months ended June 30, 2021) $ 6,667 2022 20,000 2023 20,000 2024 13,333 Total long-term debt, of which $ 16,667 is current and $ 43,333 is noncurrent $ 60,000 |

Leases [Abstract] | |
Leases | 6. LEASES The Company has operating and finance leases for offices, manufacturing and warehouse facilities and computer equipment. The Company’s leases have remaining lease terms of one year to ten years . Options to renew or extend leases beyond their initial term have been excluded from measurement of the ROU assets and lease liabilities for the majority of leases as exercise is not reasonably certain. The weighted average remaining lease term and the discount rate for the reporting periods is as follows: June 30, 2021 December 31, 2020 Operating Leases Weighted average remaining lease term (years) 3.5 3.2 Weighted average discount rate 5.61 % 5.68 % Finance leases Weighted average remaining lease term (years) 9.1 9.7 Weighted average discount rate 6.91 % 6.91 % In connection with the terms of the Company’s corporate headquarters lease, a letter of credit for $ 1,250 was issued to the building lessor in October 2015. The letter of credit is renewed annually and remains outstanding as of June 30, 2021. The components of lease expense are as follows: Three Months Ended Six Months Ended June 30, June 30, 2021 2020 2021 2020 Operating lease cost $ 203 $ 340 $ 481 $ 690 Finance lease cost: Amortization of right-of-use assets 242 263 484 526 Interest on lease liabilities 200 212 403 428 Total finance lease cost $ 442 $ 475 $ 887 $ 954 Short term lease expense was not significant for the three and six months ended June 30, 2021 and 2020.

Commitments and Contingencies [Abstract] | |
Commitments and Contingencies | 7. COMMITMENTS AND CONTINGENCIES Royalty Agreements. The Company has royalty agreements in place with terms that include payment of royalties of 3 % to 5 % of specified product sales. One royalty agreement remains in effect through 2025, while the other agreement remains in effect the later of 2023 or until expiration of the underlying patents or patent applications. Parties to the royalty agreements have the right at any time to terminate the agreement immediately for cause. Royalty expense of $ 842 and $ 505 was recorded for the three months ended June 30, 2021 and 2020 and $ 1,564 and $ 1,181 for the six months ended June 30, 2021 and 2020. Purchase Agreements. The Company enters into standard purchase agreements with certain vendors in the ordinary course of business, generally with terms that allow cancellation. The Company is committed to funding renovation of a recently purchased building for additional manufacturing capacity. The Company estimates the cost of the construction project to be approximately $ 5,500 . Legal. The Company may, from time to time, become a party to legal proceedings. Such matters are subject to many uncertainties and to outcomes of which the financial impacts are not predictable with assurance and that may not be known for extended periods of time. A liability is established once management determines a loss is probable and an amount that can be reasonably estimated. The Company received a Civil Investigative Demand (CID) from the U.S. Department of Justice (USDOJ) in December 2017 stating that it is investigating the Company to determine whether the Company has violated the False Claims Act, relating to the promotion of certain medical devices related to the treatment of atrial fibrillation for off-label use and submitted or caused to be submitted false claims to certain federal and state health care programs for medically unnecessary healthcare services related to the treatment of atrial fibrillation. The CID covers the period from January 2010 to December 2017 and required the production of documents and answers to written interrogatories. The Company had no knowledge of the investigation prior to receipt of the CID. The Company maintains rigorous policies and procedures to promote compliance with the False Claims Act and other applicable regulatory requirements. The Company provided the USDOJ with documents and answers to the written interrogatories. In March 2021, USDOJ informed the Company that its investigation was based on a lawsuit brought under federal and state False Claims Acts, and that the United States and the various states named in the lawsuit were electing not to intervene in the case. USDOJ subsequently filed a Notice of Election to Decline Intervention and to Unseal Complaint, and the case was unsealed. It is not possible to predict when this matter may be resolved or what impact, if any, the outcome of this matter might have on our consolidated financial position, results of operations, or cash flows. The Company acquired nContact Surgical, Inc. pursuant to a merger agreement dated October 4, 2015. The merger agreement provided for contingent consideration or “earnout” to be paid upon attaining specified regulatory approvals and clinical and revenue milestones. The merger agreement’s earnout provisions required the Company to deliver periodic earnout reports to a designated representative of former nContact stockholders. In response to the reports delivered in and after February 2018, the Company received letters from representatives purporting to serve as “earnout objection statements” (as that term is defined in the merger agreement) and claim that for purposes of determining the commercial milestone payment, the Company should be including revenues of certain additional items and products that the Company has not included in its earnout statements. During February 2021, the Company entered into a settlement agreement with the former nContact stockholders requiring payment of $ 6,000 . The Company recorded the $ 6,000 settlement as a component of current liabilities as of December 31, 2020 as the underlying cause occurred prior to December 31, 2020, and has made the majority of the settlement payment as of June 30, 2021. |
Revenue

Revenue [Abstract] | |
Revenue | 8. REVENUE Revenue is generated primarily from the sale of medical devices. The Company recognizes revenue in an amount that reflects the consideration the Company expects to be entitled to in exchange for those devices when control of promised devices is transferred to customers. At contract inception, the Company assesses the products promised in its contracts with customers and identifies a performance obligation for each promise to transfer to the customer a product that is distinct. The Company’s devices are distinct and represent performance obligations. These performance obligations are satisfied, and revenue is recognized at a point in time upon shipment or delivery of products. Sales of devices are categorized as follows: open ablation, minimally invasive ablation, appendage management and valve tools. Shipping and handling activities performed after control over products transfers to customers are considered activities to fulfill the promise to transfer the products rather than as separate promises to customers. Products are sold primarily through a direct sales force and through distributors in certain international markets. Terms of sale are generally consistent for both end-users and distributors except that payment terms are generally net 30 days for end-users and net 60 days for distributors, with some exceptions. The Company does not maintain any post-shipping obligations to customers. No installation, calibration or testing of products is performed by the Company subsequent to shipment in order to render products operational. Significant judgments and estimates involved in the Company’s recognition of revenue include the estimation of a provision for returns. The Company estimates the provision for sales returns and allowances using the expected value method based on historical experience and other factors that we believe could impact our expected returns, including defective or damaged products and invoice adjustments. In the normal course of business, the Company generally does not accept product returns unless a product is defective as manufactured. The Company does not provide customers with the right to a refund. The Company expects to be entitled to the total consideration for the products ordered by customers as product pricing is fixed according to the terms of customer contracts and payment terms are short. Payment terms fall within the one-year guidance for the practical expedient which allows the Company to forgo adjustment of the promised amount of consideration for the effects of a significant financing component. The Company excludes taxes assessed by governmental authorities on revenue-producing transactions from the measurement of the transaction price. Costs associated with product sales include commissions and royalties. Considering that product sales are performance obligations in contracts that are satisfied at a point in time, commission expense associated with product sales and royalties paid based on sales of certain products is incurred at that point in time rather than over time. Therefore, the Company applies the practical expedient and recognizes commissions and royalties as expense when incurred because the expense is incurred at a point in time and the amortization period is less than one year. Commissions are included in selling expense while royalties are included in cost of revenue. See Note 11 for disaggregated revenue by geographic area and by product category. |

Income Tax Provision [Abstract] | |
Income Tax Provision | 9. INCOME TAX PROVISION The Company files federal, state, and foreign income tax returns in jurisdictions with varying statutes of limitations. The Company uses the asset and liability method to determine its provision for income taxes. The Company’s provision for income taxes in interim periods is computed by applying the discrete method and is based on financial results through the end of the interim period. The Company determined that using the discrete method is more appropriate than using the annual effective tax rate method. The Company is unable to estimate the annual effective tax rate with sufficient precision to use the effective tax rate method, which requires a full-year projection of income. The effective tax rate for the three months ended June 30, 2021 and 2020 was ( 0.41 %) and ( 0.15 %). The effective tax rate for the six months ended June 30, 2021 and 2020 was ( 0.29 %) and ( 0.08 %). The Company’s worldwide effective tax rate differs from the US statutory rate of 21 % primarily due to the Company’s valuation allowance in the United States and Netherlands. Federal, state and local returns of the Company are routinely subject to review by various taxing authorities. The Company has not accrued any interest and penalties related to unrecognized income tax benefits as a result of offsetting of net operating losses. However, if required, the Company will recognize interest and penalties within income tax expense and within the related tax liability. |

Equity Compensation Plans [Abstract] | |
Equity Compensation Plans | 10. EQUITY COMPENSATION PLANS The Company has two share-based incentive plans: the 2014 Stock Incentive Plan (2014 Plan) and the 2018 Employee Stock Purchase Plan (ESPP). Stock Incentive Plan Under the 2014 Plan, the Board of Directors may grant incentive stock options to Company employees and may grant restricted stock awards or restricted stock units (collectively RSAs), nonstatutory stock options, performance share awards (PSAs) or stock appreciation rights to Company employees, directors and consultants. The Compensation Committee of the Board of Directors, as the administrator of the 2014 Plan, has the authority to determine the terms of any awards, including the number of shares subject to each award, the exercisability of the awards and the form of consideration. As of June 30, 2021, 12,899 shares of common stock had been reserved for issuance under the 2014 Plan, and 1,493 shares were available for future grants. Stock options, restricted stock awards and restricted stock units granted generally vest at a rate of 33.3 % on the first, second and third anniversaries of the grant date. Stock options generally expire ten years from the date of grant. The award agreements for the PSAs provide that each PSA that vests represents the right to receive one share of the Company’s common stock at the end of the performance period. With respect to the PSAs, the number of shares that vest and are issued to the recipient is based upon the Company’s performance with respect to specified targets at the end of the three year performance period. Payout opportunities range from 0 % to 100 % of the target amount for awards granted prior to 2021, while awards granted in 2021 have payout opportunities ranging from 0 % to 200 % of the target amount. These ranges are used to calculate the number of shares that will be issuable when the award vests. All or a portion of the PSAs may vest following a change of control or a termination of service by reason of death or disability. PSAs granted prior to 2021 have performance targets based on the Company’s revenue compound annual growth rate (CAGR) over the three year performance period. PSAs granted in 2021 have two equally weighted performance targets measured at the end of the three year performance period: (i) the Company’s revenue CAGR; and (ii) relative total shareholder return (TSR). TSR is measured against the Nasdaq Health Care Index constituents and the 20 -trading-day average stock price prior to the end of the performance period over the 20 -trading-day average stock price prior to the beginning of the performance period. The performance and market condition payouts will be determined independently and accumulated to determine the total payout for the three year performance period, subject to the maximum payout defined in the PSA agreements. Employee Stock Purchase Plan Under the ESPP, shares of the Company’s common stock may be purchased at a discount ( 15 %) of the lesser of the closing price of the Company’s common stock on the first trading day or the last trading day of the offering period. The offering period (currently six months ) and the offering price are subject to change. Participants may not purchase a value of more than $ 25 of the Company’s common stock in a calendar year and may not purchase a value of more than 3 shares during an offering period. As of June 30, 2021, there were 338 shares available for future issuance under the ESPP. Expense Information Under FASB ASC 718 The following table summarizes the allocation of share-based compensation expense: Three Months Ended Six Months Ended June 30, June 30, 2021 2020 2021 2020 Cost of revenue $ 598 $ 351 $ 1,017 $ 638 Research and development expenses 1,083 1,017 2,020 1,672 Selling, general and administrative expenses 5,460 4,825 10,708 8,267 Total $ 7,141 $ 6,193 $ 13,745 $ 10,577 |

Description of Business and Summary of Significant Accounting Policies [Abstract] | |
Nature of the Business | Nature of the Business —The “Company” or “AtriCure” consists of AtriCure, Inc. and its wholly-owned subsidiaries. The Company is a leading innovator in treatments for atrial fibrillation (Afib) and left atrial appendage (LAA) management and sells its products to medical centers globally through its direct sales force and distributors. |
Basis of Presentation | Basis of Presentation —The accompanying interim financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (SEC). The accompanying interim financial statements are unaudited, but in the opinion of the Company’s management, contain all normal, recurring adjustments considered necessary to present fairly the financial position, results of operations and cash flows for the periods presented in conformity with accounting principles generally accepted in the United States of America (GAAP) applicable to interim periods. Certain information and footnote disclosures included in annual financial statements prepared in accordance with GAAP have been omitted or condensed. The Company believes the disclosures herein are adequate to make the information presented not misleading. Results of operations are not necessarily indicative of the results expected for the full year or for any future period. The accompanying Condensed Consolidated Financial Statements should be read in conjunction with the Company’s audited financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 filed with the SEC. All intercompany accounts and transactions have been eliminated in consolidation. |
Cash and Cash Equivalents | Cash and Cash Equivalents —The Company considers highly liquid investments with maturities of three months or less at the date of purchase as cash equivalents. Cash equivalents include demand deposits, money market funds and repurchase agreements on deposit with financial institutions. |
Investments | Investments —The Company invests primarily in government and agency obligations, corporate bonds, commercial paper and asset-backed securities and classifies all investments as available-for-sale. Investments maturing in less than one year are classified as short-term investments. Investments are recorded at fair value, with unrealized gains and losses recorded as accumulated other comprehensive income (loss). Gains and losses are recognized using the specific identification method when securities are sold and are included in interest income. |
Revenue Recognition | Revenue Recognition— The Company recognizes revenue when control of promised goods is transferred to customers in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods. This generally occurs upon shipment of goods to customers. See Note 8 for further discussion on revenue. |
Sales Returns and Allowances | Sales Returns and Allowances —The Company maintains a provision for potential returns of defective or damaged products and invoice adjustments. The Company adjusts the provision using the expected value method based on historical experience. Increases to the provision reduce revenue, and the provision is included in accrued liabilities. |
Allowance for Credit Losses on Accounts Receivable | Allowance for Credit Losses on Accounts Receivable —The Company evaluates the expected credit losses of accounts receivable, considering historical credit losses, current customer-specific information and other relevant factors when determining the allowance. An increase to the allowance for credit losses results in a corresponding increase in selling, general and administrative expenses. The Company charges off uncollectible receivables against the allowance when all attempts to collect the receivable have failed. The Company’s history of write-offs has not been significant. |
Inventories | Inventories —Inventories are stated at the lower of cost or net realizable value based on the first-in, first-out cost method (FIFO) and consist of raw materials, work in process and finished goods. The Company’s industry is characterized by rapid product development and frequent new product introductions. Uncertain timing of regulatory approvals, variability in product launch strategies and variation in product use all impact inventory reserves for excess, obsolete and expired products. An increase to inventory reserves results in a corresponding increase in cost of revenue. Inventories are written off against the reserve when they are physically disposed. Inventories consist of the following: June 30, December 31, 2021 2020 Raw materials $ 12,381 $ 11,966 Work in process 3,599 2,424 Finished goods 21,628 20,636 Inventories $ 37,608 $ 35,026 |
Property and Equipment | June 30, December 31, 2021 2020 Raw materials $ 12,381 $ 11,966 Work in process 3,599 2,424 Finished goods 21,628 20,636 Inventories $ 37,608 $ 35,026 Property and Equipment —Property and equipment is stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of assets. The estimated useful life by major asset category is the following: Estimated Useful Life Generators and related equipment 1-3 years Building and building under finance lease 15 - 20 years Computers, software and office equipment 3 years Machinery and equipment 3 - 7 years Furniture and fixtures 3 - 7 years Leasehold improvements 5 - 15 years Equipment under finance leases 3 - 5 years The Company assesses the useful lives of property and equipment at least annually and retires assets no longer in use. Maintenance and repair costs are expensed as incurred. The Company reviews property and equipment for impairment at least annually using its best estimates based on reasonable and supportable assumptions and expected future cash flows. Property and equipment impairments have not been significant. The Company’s radiofrequency (RF) and cryo generators are generally placed with customers that use the Company’s disposable products. The estimated useful lives of generators are based on anticipated usage by customers and may change in future periods with changes in usage or introduction of new technology. Depreciation of generators and related equipment, which is included in cost of revenue, was $ 601 and $ 635 for the three months ended June 30, 2021 and 2020 and $ 1,203 and $ 1,285 for the six months ended June 30, 2021 and 2020. As of June 30, 2021 and December 31, 2020, the net carrying value of generators and related equipment included in net property and equipment was $ 3,542 and $ 3,410 . |
Leases | Leases — The Company leases office, manufacturing and warehouse facilities and computer equipment under leases that qualify as either financing or operating leases, as determined at the inception of the lease arrangement. Lease assets represent the right to use an underlying asset for the lease term, and lease liabilities represent the obligation to make lease payments arising from the lease. Lease assets and liabilities are measured and recorded at the commencement date based on the present value of lease payments over the lease term. Lease assets and liabilities exclude lease incentives and include options to extend or terminate when it is reasonably certain the Company will exercise that option. The Company uses the implicit rate when readily determinable; however, most of the leases do not provide an implicit rate and therefore, the Company uses the incremental borrowing rate based on the information available at measurement. The Company applies the short-term lease recognition exemption, recognizing lease payments in profit or loss, for leases that have a lease term of 12 months or less at commencement and do not include an option to extend the lease whose exercise is reasonably certain. For real estate and equipment leases, the Company accounts for the lease and non-lease components as a single lease component. Additionally, the portfolio approach is applied for the operating leases based on the terms of the underlying leases. Operating leases are included in operating lease right-of-use (ROU) assets and operating lease liabilities, while finance leases are included in property and equipment and finance lease liabilities. The short-term portions of both lease liabilities are included in other current liabilities and current maturities of debt and leases. Operating lease expense is recognized on a straight-line basis over the lease term. See Note 6 for further discussion. |
Intangible Assets | Intangible Assets —Intangible assets with determinable useful lives are amortized on a straight-line basis over the estimated periods benefited. Intangible assets include In Process Research and Development (IPR&D), representing the value of technology acquired in business combinations that has not yet reached technological feasibility. The primary basis for determining technological feasibility is obtaining specific regulatory approvals. IPR&D is accounted for as an indefinite-lived intangible asset until completion or abandonment of the IPR&D project. Upon completion of the development project, IPR&D will be amortized over its estimated useful life. If the IPR&D project is abandoned or regulatory approvals are not obtained, the Company may have a full or partial impairment charge related to the IPR&D, calculated as the excess carrying value of the IPR&D asset over the estimated fair value. As of June 30, 2021, the IPR&D asset represents an estimate of the fair value of the pre-market approval (PMA) that could result from the aMAZE™ IDE clinical trial. See Note 12 for further discussion. Through April 2021, the IPR&D asset also included an estimate of the fair value of the PMA that could result from the CONVERGE IDE clinical trial. The Company received PMA approval for CONVERGE on April 28, 2021 and began amortizing the technology asset over an estimated fifteen year life. The Company reviews intangible assets at least annually for impairment using its best estimates based on reasonable and supportable assumptions and projections. The Company performs impairment testing annually on October 1 or more often if impairment indicators are present. |
Goodwill | Goodwill— Goodwill represents the excess of purchase price over the fair value of the net assets acquired in business combinations. The Company’s goodwill is accounted for in a single reporting unit representing the Company as a whole. The Company performs impairment testing annually on October 1 or more often if impairment indicators are present. |
Contingent Consideration and Other Noncurrent Liabilities | Contingent Consideration and Other Noncurrent Liabilities— This balance consists of contingent consideration from business combinations, as well as deferred payroll taxes as a result of the Coronavirus Aid, Relief, and Economic Security Act (CARES Act), asset retirement obligations and other contractual obligations. The contingent consideration balance is included in noncurrent liabilities as settlement is expected to be made primarily in shares of the Company’s common stock pursuant to the SentreHEART, Inc. (SentreHEART) merger agreement. |
Other Income (Expense) | Other Income (Expense) — Other income (expense) consists primarily of foreign currency transaction gains and losses generated by settlements of intercompany balances denominated in Euros and customer invoices transacted in British Pounds. |
Taxes | Taxes —Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred income tax assets and liabilities from a change in tax rates is recognized in the period that includes the enactment date. The Company’s estimate of the valuation allowance for deferred income tax assets requires significant estimates and judgments about future operating results. Deferred income tax assets are reduced by valuation allowances if, based on the consideration of all available evidence, it is more-likely-than-not that the deferred income tax asset will not be realized. Significant weight is given to evidence that can be objectively verified. The Company evaluates deferred income tax assets on an annual basis to determine if valuation allowances are required. Deferred income tax assets are realized by having sufficient future taxable income to allow the related tax benefits to reduce taxes otherwise payable. The sources of taxable income that may be available to realize the benefit of deferred income tax assets are future taxable income, future reversals of existing taxable temporary differences, carryforwards and tax planning strategies that are both prudent and feasible. In evaluating the need for a valuation allowance, the existence of cumulative losses in recent years is significant objectively verifiable negative evidence that must be overcome by objectively verifiable positive evidence to avoid the need to record a valuation allowance. The Company has recorded a full valuation allowance against substantially all net deferred income tax assets as it is more-likely-than-not that the benefit of the deferred income tax assets will not be recognized in future periods. The Company has not reclassified income tax effects of the Tax Cuts and Jobs Act within accumulated other comprehensive income (loss) to retained earnings due to its full valuation allowance. |
Net Loss Per Share | Net Loss Per Share —Basic and diluted net loss per share is computed by dividing the net loss by the weighted average number of common shares outstanding during the period. Since the Company has experienced net losses for all periods presented, net loss per share excludes the effect of stock options, restricted stock shares, restricted stock units and performance award shares totaling 1,807 and 2,770 as of June 30, 2021 and 2020 because they are anti-dilutive. Therefore, the number of shares calculated for basic net loss per share is also used for the diluted net loss per share calculation. |
Comprehensive Loss and Accumulated Other Comprehensive Income (Loss) | Comprehensive Loss and Accumulated Other Comprehensive Income (Loss) —In addition to net losses, the comprehensive loss includes foreign currency translation adjustments and unrealized gains (losses) on investments. Accumulated other comprehensive income (loss) consisted of the following, net of tax: Three Months Ended Six Months Ended June 30, June 30, 2021 2020 2021 2020 Total accumulated other comprehensive income (loss) at beginning of period $ ( 18 ) $ ( 371 ) $ 312 $ ( 158 ) Unrealized Gains (Losses) on Investments Balance at beginning of period $ 23 $ 37 $ 54 $ 100 Other comprehensive (loss) income before reclassifications ( 132 ) 174 ( 163 ) 92 Amounts reclassified from accumulated other comprehensive income to other income (expense) — — — 19 Balance at end of period $ ( 109 ) $ 211 $ ( 109 ) $ 211 Foreign Currency Translation Adjustment Balance at beginning of period $ ( 41 ) $ ( 408 ) $ 258 $ ( 258 ) Other comprehensive income (loss) before reclassifications 36 109 ( 262 ) ( 113 ) Amounts reclassified from accumulated other comprehensive income (loss) to other income (expense) 27 ( 8 ) 26 64 Balance at end of period $ 22 $ ( 307 ) $ 22 $ ( 307 ) Total accumulated other comprehensive loss at end of period $ ( 87 ) $ ( 96 ) $ ( 87 ) $ ( 96 ) |
Research and Development Costs | Research and Development Costs —Research and development costs are expensed as incurred. These costs include compensation and other internal and external costs associated with the development of and research related to new and existing products or concepts, preclinical studies, clinical trials and related regulatory activities, as well as amortization of technology assets. |
Advertising Costs | Advertising Costs — The Company expenses advertising costs as incurred. Advertising costs were not significant during the three and six months ended June 30, 2021 and 2020. |
Share-Based Compensation | Share-Based Compensation —The Company records share-based compensation for all share-based payment awards, including stock options, restricted stock awards, restricted stock units, performance shares (PSAs) and stock purchases related to an employee stock purchase plan, based on estimated fair values. The value of the portion of an award that is ultimately expected to vest, net of estimated forfeitures, is recognized as expense over the service period. The Company estimates forfeitures at the time of grant and revises them, as necessary, in subsequent periods as actual forfeitures differ from those estimates. The Company recognized share-based compensation expense of $ 7,141 and $ 6,193 for the three months ended June 30, 2021 and 2020 and $ 13,745 and $ 10,577 for the six months ended June 30, 2021 and 2020. The Company estimates the fair value of time-based options on the date of grant using the Black-Scholes option-pricing model (Black-Scholes model). The Company’s determination of the fair value is affected by the Company’s stock price, as well as assumptions regarding several subjective variables. These variables include, but are not limited to, the Company’s expected stock price volatility over the term of the awards and actual and projected employee stock option exercise behaviors. The Company estimates the fair value of restricted stock awards and restricted stock units based upon the grant date closing market price of the Company’s common stock. The Company estimates the fair value of PSAs with a performance condition based on the closing stock price on the date of grant assuming the performance goal will be achieved and may adjust expense over the performance period based on changes to estimates of performance target achievement. If such goals are not met or service is not rendered for the requisite service period, no compensation cost is recognized, and any recognized compensation cost will be reversed. For PSAs with a market condition, a Monte Carlo simulation is performed to estimate the fair value on the date of grant, and compensation cost is recognized over the requisite service period as the employee renders service, even if the market condition is not satisfied. The Company’s determination of the fair value is affected by the Company and the peer group’s stock price, as defined by the award agreement, at the beginning of the service period and grant date, the expected volatility of the Company and peer group’s stock price over the performance period and the correlation coefficient of the daily returns for the Company and peer group over the performance period. The Company also has an employee stock purchase plan (ESPP) which is available to all eligible employees as defined by the plan document. Under the ESPP, shares of the Company’s common stock may be purchased at a discount. The Company estimates the number of shares to be purchased under the ESPP at the beginning of each purchase period based upon the fair value of the stock at the beginning of the purchase period using the Black-Scholes model and records estimated compensation expense during the purchase period. Expense is adjusted at the time of stock purchase. |
Use of Estimates | Use of Estimates —The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, including intangible assets, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expense during the reporting period. Estimates are based on historical experience, where applicable, and other assumptions believed to be reasonable by management. Actual results could differ from those estimates. |
