Liquidity and Management P lans The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. As of December 31, 2016, $8,086,000 $6,791,000. $68,622,000 December 31, 2016. six Management of the Company intends to raise additional funds through the issuance of equity securities. There can be no assurance that such financing will be available or on terms which are favorable to the Company. Failure to generate sufficient cash flows from operations, raise additional capital or reduce certain discretionary spending could have a material adverse effect on the Company’s ability to achieve its intended business objectives. These factors raise substantial doubt about the Company’s ability to continue as a going concern. The accompanying consolidated financial statements do not include any adjustments that might be necessary if the Company is unable to continue as a going concern. |

All significant intercompany accounts and transactions have been eliminated in consolidation. Reclassification of Prior Year Presentation Certain prior year amounts have been reclassified for consistency with the current period presentation.

We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may Cash and Cash Equivalents The Company considers all highly liquid investments purchased with an original maturity of three one may, Concentration of Credit Risk and Other Risks and Uncertainties To achieve profitable operations, the Company must successfully develop, manufacture, and market its products. There can be no assurance that any such products can be developed or manufactured at an acceptable cost and with appropriate performance characteristics, or that such products will be successfully marketed. These factors could have a material adverse effect upon the Company’s financial results, financial position, and future cash flows. The Company’s products may The Company is subject to risks common to companies in the medical device industry including, but not limited to, new technological innovations, dependence on key personnel, protection of proprietary technology, compliance with government regulations, uncertainty of market acceptance of products, product liability, and the need to obtain additional financing. The Company’s ultimate success is dependent upon its ability to raise additional capital and to successfully develop and market its products. The Company designs, develops, manufactures and markets a medical device for the non-invasive treatment of vaginal laxity that it refers to as the Geneveve™, which includes the Viveve System™, single-use treatment tips and other ancillary consumables. The Company outsources the manufacture and repair of the Viveve System to a single contract manufacturer. Also, certain other components and materials that comprise the Geneveve are currently manufactured by a single supplier or a limited number of suppliers. A significant supply interruption or disruption in the operations of the contract manufacturer or these third During the year ended December 31, 2016, three 78% December 31, 2015, four 87% December 31, 2016, three 81% December 31, 2015, three 86% Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are recorded at the invoiced amount and are not interest bearing. six may six The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. The Company makes ongoing assumptions relating to the collectibility of its accounts receivable in its calculation of the allowance for doubtful accounts. In determining the amount of the allowance, the Company makes judgments about the creditworthiness of customers based on ongoing credit evaluations and assesses current economic trends affecting its customers that might impact the level of credit losses in the future and result in different rates of bad debts than previously seen. The Company also considers its historical level of credit losses. As of December 31, 2016 2015, no Inventory Inventory is stated at the lower of cost or market. lnventory as of December 31, 2016 $181,000 $2,506,000 December 31, 2015 Cost is determined on an actual cost basis on a first first As part of the Company’s normal business, the Company generally utilizes various finished goods inventory as sales demos to facilitate the sale of its products to prospective customers. The Company is amortizing these demos over an estimated useful life of five December 31, 2016 2015. Property and Equipment, net Property and equipment are stated at cost, net of accumulated depreciation and amortization. Depreciation of property and equipment is computed using the straight line method over their estimated useful lives of three seven Impairment of Long-Lived Assets The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset might not be recoverable. When such an event occurs, management determines whether there has been an impairment by comparing the anticipated undiscounted future net cash flows to the related asset’s carrying value. If an asset is considered impaired, the asset is written down to fair value, which is determined based either on discounted cash flows or appraised value, depending on the nature of the asset. The Company has not identified any such impairment losses to date. Revenue Recognition The Company recognizes revenue from the sale of its products, the Viveve System, single-use treatment tips and ancillary consumables. Revenue is recognized upon shipment, provided that persuasive evidence of an arrangement exists, the price is fixed or determinable and collection of the resulting receivable is reasonably assured. Sales of our products are subject to regulatory requirements that vary from country to country. The Company has regulatory clearance, or can sell its products without a clearance, in many countries throughout the world, including countries within the following regions: North America, Latin America, Europe, the Middle East and Asia Pacific. The Company does not provide its customers with a right of return. Customer Advance Payments From time to time, customers will pay for a portion of the products ordered in advance. Upon receipt of such payments, the Company records the customer advance payment as a component of accrued liabilities. The Company will remove the customer advance payment from accrued liabilities when revenue is recognized. Product Warranty The Company’s products are generally subject to a one Shipping and Handling Costs The Company includes amounts billed for shipping and handling in revenue and shipping and handling costs in cost of revenue. Advertising Costs Advertising costs are charged to selling, general and administrative expenses as incurred. Advertising expenses, which are recorded in selling, general and administrative expenses, were immaterial for the years ended December 31, 2016 2015. Research and Development Research and development costs are charged to operations as incurred. Research and development costs include, but are not limited to, payroll and personnel expenses, prototype materials, laboratory supplies, consulting costs, and allocated overhead, including rent, equipment depreciation, and utilities. Income Taxes The provision for income taxes is determined using the asset and liability approach of accounting for income taxes. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income taxes represents income taxes paid or payable for the current year plus the change in deferred taxes during the year. Deferred taxes result from differences between the financial and tax basis of the Company’s assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. The Company must assess the likelihood that the Company’s deferred tax assets will be recovered from future taxable income, and to the extent the Company believes that recovery is not likely, the Company establishes a valuation allowance. Management judgment is required in determining the Company’s provision for income taxes, deferred tax assets and liabilities, and any valuation allowance recorded against the net deferred tax assets. The Company recorded a full valuation allowance as of December 31, 2016 2015. The Company recognizes in the financial statements the impact of a tax position, if that position is more likely than not of being sustained on audit, based on the technical merits of the position. The Company’s policy is to recognize interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense. The Company does not believe there are any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly increase or decrease within 12 Accounting for Stock-Based Compensation Share-based compensation cost is measured at grant date, based on the fair value of the award, and is recognized as expense over the employee’s service period. The Company recognizes compensation expense on a straight-line basis over the requisite service period of the award. We determined that the Black-Scholes option pricing model is the most appropriate method for determining the estimated fair value for stock options. The Black-Scholes option pricing model requires the use of highly subjective and complex assumptions which determine the fair value of share-based awards, including the option’s expected term and the price volatility of the underlying stock. Equity instruments issued to nonemployees are recorded at their fair value on the measurement date and are subject to periodic adjustment as the underlying equity instruments vest. Comprehensive Loss Comprehensive loss represents the changes in equity of an enterprise, other than those resulting from stockholder transactions. Accordingly, comprehensive loss may December 31, 2016 2015, Net Loss per Share The Company’s basic net loss per share is calculated by dividing the net loss by the weighted average number of shares of common stock outstanding for the period. The diluted net loss per share is computed by giving effect to all potentially dilutive common stock equivalents outstanding during the period. For purposes of this calculation, stock options and warrants to purchase common stock and restricted common stock awards are considered common stock equivalents. For periods in which the Company has reported net losses, diluted net loss per share is the same as basic net loss per share, since dilutive common shares are not assumed to have been issued if their effect is anti-dilutive. The following securities were excluded from the calculation of net loss per share because the inclusion would be anti-dilutive.

Fair Value Disclosures [Text Block] | 3. Fair Value Measurements The Company recognizes and discloses the fair value of its assets and liabilities using a hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to valuations based upon unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 3 Level 1 Inputs used to measure fair value are unadjusted quoted prices that are available in active markets for the identical assets or liabilities as of the reporting date. Therefore, determining fair value for Level 1 Level 2 Pricing is provided by third Level 3 Inputs used to measure fair value are unobservable inputs that are supported by little or no market activity and reflect the use of significant management judgment. These values are generally determined using pricing models for which the assumptions utilize management’s estimates of market participant assumptions. The determination of fair value for Level 3 Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires management to make judgments and consider factors specific to the asset or liability. There were no financial instruments that were measured at fair value on a recurring basis as of December 31, 2016 2015. The carrying amounts of the Company’s financial assets and liabilities, including cash and cash equivalents, accounts receivable, accounts payable, and accrued expenses as of December 31, 2016 2015 There were no changes in valuation techniques from prior periods. |

Pursuant to these arrangements, the Company indemnifies, holds harmless and agrees to reimburse the indemnified parties for losses suffered or incurred by the indemnified party, in connection with performance of services within the scope of the agreement, breach of the agreement by the Company, or noncompliance of regulations or laws by the Company, in all cases provided the indemnified party has not breached the agreement and/or the loss is not attributable to the indemnified party’s negligence or willful malfeasance. The term of these indemnification agreements is generally perpetual any time after the execution of the agreement. The maximum potential amount of future payments the Company could be required to make under these arrangements is not determinable. The Company has never incurred costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, the Company believes the estimated fair value of these agreements is minimal. Loss Contingencies The Company is or has been subject to proceedings, lawsuits and other claims arising in the ordinary course of business. The Company evaluates contingent liabilities, including threatened or pending litigation, for potential losses. If the potential loss from any claim or legal proceeding is considered probable and the amount can be estimated, the Company accrues a liability for the estimated loss. Because of uncertainties related to these matters, accruals are based upon the best information available. For potential losses for which there is a reasonable possibility (meaning the likelihood is more than remote but less than probable) that a loss exists, the Company will disclose an estimate of the potential loss or range of such potential loss or include a statement that an estimate of the potential loss cannot be made. As additional information becomes available, the Company reassesses the potential liability related to pending claims and litigation and may |

The Company estimated the fair value of stock options using the Black-Scholes option pricing model. The fair value of employee stock options is being amortized on a straight-line basis over the requisite service period of the awards. The fair value of employee stock options granted was estimated using the following weighted average assumptions: Year Ended December 31, 2016 2015 Expected term (in years) 5 5 Average volatility 49 % 63 % Risk-free interest rate 1.78 % 1.70 % Dividend yield 0 % 0 % During the year ended December 31, 2016, 59,125 $4.60 no December 31, 2015. no December 31, 2016 2015.

The expected stock price volatility is based on analysis of the Company’s stock price history over a period commensurate with the expected term of the options, trading volume of comparable companies’ stock, look-back volatilities and Company specific events that affected volatility in a prior period. The expected term of employee stock options represents the weighted average period the stock options are expected to remain outstanding and is based on the history of exercises and cancellations on all past option grants made by the Company, the contractual term, the vesting period and the expected remaining term of the outstanding options. The risk-free interest rate is based on the U.S. Treasury interest rates whose term is consistent with the expected life of the stock options.

Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income taxes represents income taxes paid or payable for the current year plus the change in deferred taxes during the year. Deferred taxes result from differences between the financial and tax basis of the Company’s assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. The Company must assess the likelihood that the Company’s deferred tax assets will be recovered from future taxable income, and to the extent the Company believes that recovery is not likely, the Company establishes a valuation allowance. Management judgment is required in determining the Company’s provision for income taxes, deferred tax assets and liabilities, and any valuation allowance recorded against the net deferred tax assets. The Company recorded a full valuation allowance as of December 31, 2016 2015. The Company recognizes in the financial statements the impact of a tax position, if that position is more likely than not of being sustained on audit, based on the technical merits of the position. The Company’s policy is to recognize interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense. The Company does not believe there are any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly increase or decrease within 12 |
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block] | Accounting for Stock-Based Compensation Share-based compensation cost is measured at grant date, based on the fair value of the award, and is recognized as expense over the employee’s service period. The Company recognizes compensation expense on a straight-line basis over the requisite service period of the award. We determined that the Black-Scholes option pricing model is the most appropriate method for determining the estimated fair value for stock options. The Black-Scholes option pricing model requires the use of highly subjective and complex assumptions which determine the fair value of share-based awards, including the option’s expected term and the price volatility of the underlying stock. Equity instruments issued to nonemployees are recorded at their fair value on the measurement date and are subject to periodic adjustment as the underlying equity instruments vest. |
Comprehensive Income, Policy [Policy Text Block] | Comprehensive Loss Comprehensive loss represents the changes in equity of an enterprise, other than those resulting from stockholder transactions. Accordingly, comprehensive loss may December 31, 2016 2015, |
Earnings Per Share, Policy [Policy Text Block] | Net Loss per Share The Company’s basic net loss per share is calculated by dividing the net loss by the weighted average number of shares of common stock outstanding for the period. The diluted net loss per share is computed by giving effect to all potentially dilutive common stock equivalents outstanding during the period. For purposes of this calculation, stock options and warrants to purchase common stock and restricted common stock awards are considered common stock equivalents. For periods in which the Company has reported net losses, diluted net loss per share is the same as basic net loss per share, since dilutive common shares are not assumed to have been issued if their effect is anti-dilutive. The following securities were excluded from the calculation of net loss per share because the inclusion would be anti-dilutive.
