Nature of the Business and Basis of Presentation [Abstract]
Nature of the Business and Basis of Presentation	1. Nature of the Business and Basis of Presentation SANUWAVE Health, Inc. and subsidiaries (“SANUWAVE” or the “Company”) is focused on the commercialization of its patented noninvasive and biological response activating medical systems for the repair and regeneration of skin, musculoskeletal tissue, and vascular structures. Basis of Presentation – The financial information as of June 30, 2023, and for the three and six months ended June 30, 2023, and 2022 is unaudited; however, in the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair statement have been included. Operating results for the three and six months ended June 30, 2023, are not necessarily indicative of the results that may be expected for any other interim period or for the year ending December 31, 2023. The condensed consolidated balance sheet on December 31, 2022, has been derived from the audited consolidated financial statements at that date but does not include all the information and disclosures required by U.S. GAAP for comprehensive financial statements. These financial statements should be read in conjunction with the Company’s December 31, 2022 Annual Report on Form 10-K filed with the SEC on March 31, 2023 (the “2022 Annual Report”). Reclassifications - Certain accounts in the prior period condensed consolidated financial statements have been reclassified to conform to the presentation of the current period condensed consolidated financial statements. These reclassifications had no effect on the previously reported operating results

Going Concern [Abstract]
Going Concern	2. Going Concern The recurring losses from operations, the events of default on the Company’s notes payable, and dependency upon future issuances of equity or other financing to fund ongoing operations have raised substantial doubt as to our ability to continue as a going concern for a period of at least twelve months from the filing of this Form 10-Q. The Company expects to devote substantial resources for the commercialization of UltraMIST and PACE systems which will require additional capital resources to remain a going concern Management’s plans are to obtain additional capital in 2023 through the conversion of outstanding warrants, issuance of common or preferred stock, securities convertible into common stock, or secured or unsecured debt. These possibilities, to the extent available, may be on terms that result in significant dilution to the Company’s existing stockholders. In addition, there can be no assurances that the Company’s plans to obtain additional capital will be successful on the terms or timeline it expects, or at all. If these efforts are unsuccessful, the Company may be required to significantly curtail or discontinue operations or, if available, obtain funds through financing transactions with unfavorable terms. The accompanying condensed consolidated financial statements have been prepared in conformity with U.S. GAAP, which contemplate continuation of the Company as a going concern and the realization of assets and satisfaction of liabilities in the normal course of business. The carrying amounts of assets and liabilities presented in the condensed consolidated financial statements do not necessarily purport to represent realizable or settlement values. The condensed consolidated financial statements do not include any adjustment that might result from the outcome of this uncertainty. The Company’s condensed consolidated financial statements do not include any adjustments relating to the recoverability of assets and classification of assets and liabilities that might be necessary should the Company be unable to continue as a going concern.

Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	3. Summary of Significant Accounting Policies Significant accounting policies followed by the Company are summarized below and should be read in conjunction with those described in Note 4 of the consolidated financial statements in our 2022 Annual Report. Estimates Significant estimates include the recording of allowances for doubtful accounts, the net realizable value of inventory, useful lives of long-lived assets, fair value of goodwill and other intangible assets, the determination of the valuation allowances for deferred taxes, estimated fair value of stock-based compensation, and the estimated fair value of financial instruments, including warrants and embedded conversion options. Revenue Recognition - The core p rinciple of Accounting Standards Codification (“ASC”) requires that an entity recognize revenu System Sales, Accessory and Part Sales - System sales, accessory and part sales include devices and applicators (new and refurbished). Performance obligations are satisfied at the point in time when the customer obtains control of the goods, which is generally at the point in time that the product is shipped. Licensing Fees - Licensing transactions include distribution licenses and intellectual property licenses. Licensing revenue is recognized as the Company satisfies its performance obligations, which may vary with the terms of the licensing agreement. Other Revenue - Other revenue primarily includes warranties, repairs, and billed freight. The Company allocates the device sales price to the product and the embedde Recent Accounting Pronouncements – In June 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which was subsequently revised by ASU 2018-19. The ASU introduces a new model for assessing impairment of most financial assets. Entities are required to use a forward-looking expected loss model, which replaces the current incurred loss model, resulting in earlier recognition of allowance for losses. The Company adopted this ASU in January 2023, and there was no material impact on the condensed consolidated financial statements.

Loss/Income per Share [Abstract]
Loss/Income per Share	4. Loss/Income per Share Diluted net (loss)/income per share is calculated by dividing the net (loss)/income attributable to common stockholders by the weighted average number of shares outstanding for the three and six months ended June 30, 2023, and 2022. The weighted average number of shares outstanding includes outstanding common stock and shares issuable for nominal consideration. Accordingly, warrants issued with a $0.01 per share exercise price, are included in weighted average shares outstanding as follows: Three Months Ended Six Months Ended (in Thousands) June 30, 2023 June 30, 2022 June 30, 2023 June 30, 2022 Weighted average shares outstanding Common shares 560,638 518,074 557,488 508,399 Common shares issuable assuming exercise of nominally priced warrants 21,691 20,486 21,691 24,191 Weighted average shares outstanding 582,329 538,560 579,179 532,590 Diluted net income/ (loss) per share is computed by dividing the net income/ (loss) attributable to common stockholders by the weighted average number of shares of common stock and diluted common stock equivalents outstanding. To the extent that securities are “anti-dilutive,” they are excluded from the calculation of diluted net loss per share. As a result of the net loss for the three and six months ended June 30, 2023, and six months ended June 30, 2022, all potentially dilutive shares in such periods were anti-dilutive and therefore excluded from the computation of diluted net loss per share. As a result of the net income for the three months ended June 30, 2022, all dilutive shares were included in the computation of diluted net income per share. Anti-dilutive equity securities consisted of the following for the six months ended June 30, 2023, and 2022, respectively: Six Months Ended (in Thousands) June 30, 2023 June 30, 2022 Common stock options 19,136 22,046 Common stock purchase warrants 1,247,911 189,157 Convertible notes payable 677,050 122,271 1,944,097 333,474

Senior Secured Debt, In Default	7. Senior Secured Debt, In Default The following table summarizes outstanding senior secured debt, in default: June 30, 2023 December 31, 2022 (in thousands) Principal Debt Discount Carrying Value Accrued Interest Principal Debt Discount Carrying Value Accrued Interest Senior secured debt $ 20,346 $ (4,223 ) $ 16,123 $ 2,676 $ 19,211 $ (4,795 ) $ 14,416 $ 1,890 Senior secured promissory note payable, in default (“Senior Secured Note”) – In August 2020, the Company entered into a Note and Warrant Purchase and Security Agreement (the “NWPSA”). In accordance with the NWPSA, the Company issued a $15 million Senior Secured Promissory Note Payable (the “Senior Secured Note”) and a warrant exercisable for shares of the Company’s common stock in exchange for cash to support operations, repay outstanding debt and close on the acquisition of the UltraMIST assets from Celularity Inc. (Celularity) among other transactions. In February 2022, the Company entered into a Second Amendment to Note and Warrant Purchase and Security Agreement (the “Second NWPSA”) for $3.0 million, for a total of $18.0 million outstanding. Along with the issuance of the note, the Company also issued warrants to purchase 16.2 million shares of common stock with an exercise price of $0.18 and 20.6 million shares of common stock. Since the combined fair value of the warrants and common stock issued as part of the Second NWPSA exceeded the face value of the note, the additional amount beyond the face value was recorded as a loss on issuance totaling $3.4 million. Interest is charged at the greater of the prime rate or 3% plus 9%. The principal increases at a rate of 3% of the outstanding principal balance (PIK interest) on each quarterly interest payment date. The original maturity date of the Senior Secured Note is September 20, 2025, and it can be prepaid. As of June 30, 2023, the Company is in default on the minimum liquidity provisions in the Senior Secured Note and, as a result, it is classified in current liabilities in the accompanying condensed consolidated balance sheets. The Company is accruing interest at the default interest rate of an incremental 5%. In June 2023, the Company entered into a Fourth Amendment to the NWPSA, which provides the Company an extension of the holder forbearing from exercising the remedies arising from the existing defaults to the earlier of the occurrence of an event of default and December 31, 2023. The amendment also added a consent fee of 2% of the original principal amount of the NWSPA, payable in cash at maturity, and defers interest that would otherwise have been due on June 30, 2023, and September 30, 2023. The interest will instead be compounded and added to the principal amount of the notes and bear interest at a rate of 20.25% per annum. The amendment also requires the Company to complete an equity financing that results in gross cash proceeds of at least $2.5 million by July 15, 2023. This financing successfully closed after June 30, 2023, as further described in Note 14. The debt issuance costs, and debt discount related to the Senior Secured Note were capitalized as a reduction in the principal amount and are being amortized to interest expense over the life of the Senior Secured Note. Interest expense for the three and six months ended June 30, 2023, totaled $1.7 and $3.3 million, respectively. Interest expense for the three and six months ended June 30, 2022, totaled $0.7 and $1.4 million, respectively.

Fair Value Measurements [Abstract]
Fair Value Measurements	10. Fair Value Measurements The Company uses various inputs to measure the outstanding warrants and certain embedded conversion features associated with a convertible debt on a recurring basis to determine the fair value of the liabilities. The following tables classify the Company’s liabilities measured at fair value on a recurring basis into the fair value hierarchy: Fair value measured at June 30, 2023 Fair value at Quoted prices in active markets Significant other observable inputs Significant unobservable inputs (in thousands) June 30, 2023 (Level 1) (Level 2) (Level 3) Warrant liability $ 14,410 $ - $ - $ 14,410 Embedded conversion option 693 - - 693 Total fair value $ 15,103 $ - $ - $ 15,103 Fair value measured at December 31, 2022 Fair value at Quoted prices in active markets Significant other observable inputs Significant unobservable inputs (in thousands) December 31, 2022 (Level 1) (Level 2) (Level 3) Warrant liability $ 1,416 $ - $ - $ 1,416 Embedded conversion option 2,340 - - 2,340 Total fair value $ 3,756 $ - $ - $ 3,756 There were no transfers among Levels 1, 2 or 3 during the three and six months ended June 30, 2023, and 2022. Both observable and unobservable inputs were used to determine the fair value of positions that the Company has classified within the Level 3 category. Unrealized gains and losses associated with liabilities within the Level 3 category include changes in fair value that were attributable to both observable (e.g. changes in market interest rates) and unobservable (e.g., changes in unobservable long-dated volatilities) inputs.

Recent Accounting Pronouncements	Recent Accounting Pronouncements – In June 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which was subsequently revised by ASU 2018-19. The ASU introduces a new model for assessing impairment of most financial assets. Entities are required to use a forward-looking expected loss model, which replaces the current incurred loss model, resulting in earlier recognition of allowance for losses. The Company adopted this ASU in January 2023, and there was no material impact on the condensed consolidated financial statements.
