Item 7.01 Regulation FD Disclosure.

On November 11, 2022, MedTech Acquisition Corporation, a Delaware corporation (“MTAC”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with MTAC Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of MTAC (“Merger Sub”), and TriSalus Life Sciences, Inc., a Delaware corporation (“TriSalus”), pursuant to which, subject to the satisfaction or waiver of certain conditions set forth therein, Merger Sub will merge with and into TriSalus (the “Merger”), with TriSalus surviving the Merger as a wholly owned subsidiary of MTAC, and with TriSalus’ equity holders receiving shares of MTAC common stock (the transactions contemplated by the Merger Agreement and the related ancillary agreements, the “Business Combination”). Upon consummation of the Business Combination, MTAC will be renamed “TriSalus Life Sciences, Inc.”

On December 21, 2022, MTAC and TriSalus circulated a video statement from Dr. Carvajal, Director of Experimental Therapeutics and Director of the Melanoma Service at Columbia University Medical Center, and made social media posts providing a further update on its ongoing Pressure-Enabled Regional Immuno-Oncology 01 and 02 clinical studies for primary and metastatic liver tumors. The video transcript and social media posts are furnished hereto as Exhibit 99.1 and Exhibit 99.2, respectively.

The information in this Item 7.01, including Exhibit 99.1 and Exhibit 99.2, is furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to liabilities under that section, and shall not be deemed to be incorporated by reference into the filings of MTAC under the Securities Act of 1933, as amended (the “Securities Act”) or the Exchange Act, regardless of any general incorporation language in such filings. This Current Report on Form 8-K will not be deemed an admission as to the materiality of any information in this Item 7.01, including Exhibit 99.1 and Exhibit 99.2.

Changes and Additional Information in Connection with SEC Filing

MTAC intends to file a registration statement on Form S-4 (the “Registration Statement”) that will include a proxy statement/prospectus of MTAC, that will be both the proxy statement to be distributed to holders of MTAC’s common stock in connection with its solicitation of proxies for the vote by MTAC’s stockholders with respect to the Business Combination and other matters as may be described in the Registration Statement, as well as the prospectus relating to the offer and sale of the securities to be issued in the Business Combination. The Registration Statement is not yet effective. The Registration Statement, including the proxy statement/prospectus contained therein, when it is declared effective by the U.S. Securities and Exchange Commission (the “SEC”), will contain important information about the Business Combination and the other matters to be voted upon at a meeting of MTAC’s stockholders to be held to approve the Business Combination and other matters (the “Special Meeting”). MTAC may also file other documents with the SEC regarding the Business Combination. MTAC stockholders and other interested persons are advised to read, when available, the Registration Statement, including the proxy statement/prospectus contained therein, as well as any amendments or supplements thereto, because they will contain important information about the Business Combination. When available, the definitive proxy statement /prospectus will be mailed to MTAC stockholders as of a record date to be established for voting on the Business Combination and the other matters to be voted upon at the Special Meeting.

Participation in Solicitation

MTAC and TriSalus and their respective directors and executive officers, under SEC rules, may be deemed to be participants in the solicitation of proxies of MTAC’s stockholders in connection with the Business Combination. Investors and security holders may obtain more detailed information regarding the names and interests in the Business Combination of MTAC’s directors and officers in MTAC’s filings with the SEC, including MTAC’s registration statement on Form S-1, which was originally filed with the SEC on November 30, 2020, as amended, and MTAC’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021, filed with the SEC on March 2, 2022 (the “2021 Form 10-K”). To the extent that holdings of MTAC’s securities have changed from the amounts reported in MTAC’s 2021 Form 10-K, such changes have been or will be reflected on Statements of Change in Ownership on Form 4 filed with the SEC. Information regarding the persons who may, under SEC rules, be deemed participants in the solicitation of proxies from MTAC’s stockholders in connection with the Business Combination will be set forth in the proxy statement/prospectus forming a part of the Registration Statement. Investors and security holders of MTAC and TriSalus are urged to carefully read in their entirety the proxy statement/prospectus and other relevant documents that will be filed with the SEC, when they become available, because they will contain important information about the Business Combination.

Investors and security holders will be able to obtain free copies of the proxy statement/prospectus and other documents containing important information about MTAC and TriSalus through the website maintained by the SEC at www.sec.gov. Copies of the documents filed with the SEC by MTAC can be obtained free of charge by directing a written request to MedTech Acquisition Corporation at 48 Maple Avenue, Greenwich, CT 06830.

The foregoing list of factors is not exclusive.

You should carefully consider the foregoing factors and other risks and uncertainties described in the “Risk Factors” section of MTAC’s 2021 Form 10-K, the preliminary proxy statement/prospectus included in the Registration Statement relating to the Business Combination, which is expected to be filed by MTAC with the SEC and other documents filed by MTAC from time to time with the SEC. These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those expressed or implied in the forward-looking statements. Forward-looking statements speak only as of the date they are made. Readers are cautioned not to put undue reliance on forward-looking statements, and none of MTAC, TriSalus, or any of their respective representatives assume any obligation and do not intend to update or revise these forward-looking statements, whether as a result of new information, future events, or otherwise. None of MTAC, TriSalus, or any of their respective representatives gives any assurance that either MTAC or TriSalus will achieve its expectations.

No Offer or Solicitation

This Current Report on Form 8-K shall not constitute an offer to sell, a solicitation of an offer to buy or a recommendation to purchase any securities, or the solicitation of any proxy, vote, consent or approval in any jurisdiction in connection with the Business Combination, nor shall there be any offer, solicitation or sale of securities in any jurisdiction in which the offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of such jurisdictions.
