Business Description and Basis of Presentation [Text Block]	Note 1. Organization and Nature of Operations *The Company* Catheter Precision, Inc. ("Catheter" or the "Company”) was incorporated in California on September 4, 2002, and reincorporated in Delaware in July 2018. Catheter was initially formed to develop, commercialize and market its advanced excimer laser-based platform for use in the treatment of vascular and dermatological immune-mediated inflammatory diseases. On January 9, 2023, Catheter entered into the Amended and Restated Agreement and Plan of Merger (the "Merger Agreement") with Catheter Precision, Inc. (“Old Catheter”), a privately held Delaware corporation. Under the terms of the Merger Agreement, Old Catheter became a wholly owned subsidiary of Catheter, together referred to as the Company, in a stock-for-stock merger transaction (the "Merger"). Prior to the Merger, Catheter developed the advanced excimer laser-based platform, which was developed as a tool in the treatment of Peripheral Artery Disease, which commonly occurs in the legs. After the Merger, and looking forward, this legacy Destruction of Arteriosclerotic Blockages by laser Radiation Ablation, laser and single-use catheter (together referred to as "DABRA") and related assets were no longer used. The Company ceased operations and marketing with respect to DABRA, and Catheter’s legacy lines of business were discontinued. The Company shifted the focus of its operations to Old Catheter’s product lines. Accordingly, the Company’s current activities primarily relate to Old Catheter’s historical business, which comprises the design, manufacture and sale of new and innovative medical technologies in the field of cardiac electrophysiology (“EP”). One of the Company’s two primary products is the VIVO System, which is an acronym for View into Ventricular Onset (“VIVO” or “VIVO System”). VIVO is a non-invasive imaging system that offers 3D cardiac mapping to help with localizing the sites of origin of idiopathic ventricular arrhythmias in patients with structurally normal hearts prior to EP procedures. The VIVO System is commercially available in the European Union and has been placed at several hospitals in Europe. United States Food and Drug Administration ("FDA") 510(k) clearance was received, and the Company began a limited commercial release of VIVO in 2021 in the United States. The Company’s newest product, LockeT® (“LockeT”), is a suture retention device indicated for wound healing by distributing suture tension over a larger area in the patient in conjunction with a figure of eight suture closure and is intended to temporarily secure sutures and aid clinicians in locating and removing sutures efficiently. In addition, LockeT is a sterile, Class I product that was registered with the FDA in February 2023, at which time initial shipments began to distributors. Clinical studies for LockeT began during the year ended December 31, 2023. These studies are planned to show the product’s effectiveness and benefits, including faster wound closure and earlier ambulation, potentially leading to early hospital discharge and cost benefits. This information is intended to provide crucial data for marketing. The Company recorded its first commercial sale of LockeT to distributors in May 2024. The Company’s product portfolio also includes the Amigo® Remote Catheter System (the "AMIGO" or "AMIGO System"), a robotic arm that serves as a catheter control device. Prior to 2018, Old Catheter marketed AMIGO. The Company owns the intellectual property related to AMIGO, and this product is under consideration for future research and development of a generation 2 product. Reverse stock split On July 3, 2024, at the annual meeting of stockholders of the Company, the stockholders approved an amendment to the Amended and Restated Certificate of Incorporation of the Company (the “Amendment”), which included a decrease in the authorized common stock and authorization for the Board, in its discretion, to effect a reverse stock split within specified parameters. The Amendment was effective July 15, 2024, reducing the authorized common stock to 30 million shares and effecting a reverse stock split in which each ten ( 10) shares of the Company’s common stock, par value $0.0001 per share, issued and outstanding immediately prior to the effective time, automatically combined into one ( 1) validly issued, fully paid and non-assessable share of the Company’s common stock, par value $0.0001 per share. No fractional shares were issued as a result of the reverse stock split. Stockholders who would otherwise have been entitled to receive a fractional share were entitled to receive their pro rata portion of the net proceeds obtained from the aggregation and sale by the exchange agent of the fractional shares resulting from the reverse stock split (reduced by any customary brokerage fees, commissions and other expenses). All references to share and per share amounts for all periods presented in the consolidated financial statements have been retrospectively restated to reflect this reverse stock split. All rights to receive shares of common stock under outstanding securities, including but not limited to, warrants and options, were adjusted to give effect to the reverse stock split. Furthermore, proportionate adjustments were made to the per share exercise price and the number of shares of Common Stock that may be purchased upon exercise of outstanding warrants and stock options granted by the Company, and the number of shares of Common Stock reserved for future issuance under the Company’s Equity Incentive Plan. *Going concern* The consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and settlement of liabilities in the normal course of business, and do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or amounts and classification of liabilities that may result from the outcome of this uncertainty. The Company has incurred recurring net losses from operations and negative cash flows from operating activities since inception. As of December 31, 2024, the Company had cash and cash equivalents of approximately $2.9 million. For the year ended December 31, 2024, the Company used $9.3 million in cash for operating activities. As of December 31, 2024, the Company had an accumulated deficit of approximately $292.4 million. Management expects operating losses and negative cash flows to continue for the foreseeable future as the Company invests in its commercial capabilities. These negative cash flows have substantially depleted the Company’s cash. Following the Merger with Old Catheter, Management further reduced costs while assuming the operating costs of Old Catheter. Management will continue to monitor its operating costs and seek to reduce its current liabilities. Such actions may impair its ability to proceed with certain strategic activities. Between May 30, 2024 and July 25, 2024, the Company issued five short-term promissory notes with related parties totaling $1.5 million with an 8% interest rate and a maturity date of August 30, 2024 (the “Related Party Notes”). On August 23, 2024, the Company amended the Related Party Notes to extend the maturity date to January 31, 2026. As part of the amendment, all interest accrued as of the amendment date was repaid to the noteholders and the contractual interest rate increased to 12% per annum as of the amendment date. See Note 9, Notes Payable for additional information. On August 30, 2024, the Company entered into an Underwriting Agreement (the “Underwriting Agreement”) with Ladenburg Thalmann & Co. Inc. as representative (the “Representative”) of the underwriters named in the Underwriting Agreement (the “Underwriters”). Pursuant to the Underwriting Agreement, the Company completed a public offering of its securities on September 3, 2024 (the “September 2024 Public Offering”) and sold an aggregate of (i) 805,900 Common Stock Units and (ii) 2,773,000 Pre-Funded Units. The Company collected gross proceeds of approximately $3.6 million before deducting underwriting discounts, commissions, and offering expenses payable by the Company of $1.0 million. See Note 13, Equity Offerings for additional information. On October 25, 2024, the Company executed the Warrant Inducement Offer Letters (the “2024 Warrant Inducement Offer”) with certain holders of the Company’s existing warrants. Following the close of the 2024 Warrant Inducement Offer, such warrant holders immediately exercised an aggregate of (i) 33,160.8 Series E Warrants, (ii) 499,909.34 Series F Warrants, (iii) 499,909.34 Series G Warrants, (iv) 1,990,000 Series H Warrants, and (v) 2,325,000 Series I Warrants (collectively the “2024 Existing Warrants”) to purchase 5,347,981 shares of the Company’s common stock at a reduced exercise price of $0.70 per share of common stock. In consideration for the immediate exercise of the 2024 Existing Warrants for cash, the Company agreed to issue unregistered new Series K Common Stock Purchase Warrants (“Series K Warrants”) to purchase up to 10,695,962 shares of common stock. The Company received aggregate gross proceeds of $3.7 million in cash, prior to deducting placement agent fees and offering expense of $0.4 million. See Note 13, Equity Offerings for additional information. Based on the Company’s liquidity resources, there is substantial doubt about the Company’s ability to continue as a going concern within 12 months from the date of issuance of the consolidated financial statements. The accompanying consolidated financial statements have been prepared on the basis of the Company continuing to operate in the normal course of business and do not reflect any adjustments to the assets and liabilities related to the substantial doubt of its ability to continue as a going concern. Management’s ability to continue as a going concern is dependent upon its ability to raise additional funding. Management plans to raise additional capital through public or private equity or debt financings to fulfill its operating and capital requirements for at least 12 months from the date of the issuance of the consolidated financial statements. However, the Company may not be able to secure such financing in a timely manner or on favorable terms, if at all. Furthermore, if the Company issues equity securities to raise additional funds, its existing stockholders may experience dilution, and the new equity securities may have rights, preferences and privileges senior to those of the Company’s existing stockholders.

Following the close of the 2024 Warrant Inducement Offer, such warrant holders immediately exercised an aggregate of (i) 33,160.8 Series E Warrants, (ii) 499,909.34 Series F Warrants, (iii) 499,909.34 Series G Warrants, (iv) 1,990,000 Series H Warrants, and (v) 2,325,000 Series I Warrants (collectively the “2024 Existing Warrants”) to purchase 5,347,981 shares of the Company’s common stock at a reduced exercise price of $0.70 per share of common stock.

Based on the Company’s liquidity resources, there is substantial doubt about the Company’s ability to continue as a going concern within 12 months from the date of issuance of the consolidated financial statements. The accompanying consolidated financial statements have been prepared on the basis of the Company continuing to operate in the normal course of business and do not reflect any adjustments to the assets and liabilities related to the substantial doubt of its ability to continue as a going concern.

Management’s ability to continue as a going concern is dependent upon its ability to raise additional funding. Management plans to raise additional capital through public or private equity or debt financings to fulfill its operating and capital requirements for at least 12 months from the date of the issuance of the consolidated financial statements. However, the Company may not be able to secure such financing in a timely manner or on favorable terms, if at all. Furthermore, if the Company issues equity securities to raise additional funds, its existing stockholders may experience dilution, and the new equity securities may have rights, preferences and privileges senior to those of the Company’s existing stockholders.
