Schedule 13D

This Amendment No. 3 (this “Amendment”) amends and supplements the beneficial ownership statement on Schedule 13D originally filed on June 5, 2018, as amended by Amendment No. 1 filed June 12, 2018 and Amendment No. 2 filed July 17, 2018 (the “Original Statement”) on behalf of HealthCor Partners Management, L.P., HealthCor Partners Management GP LLC, HealthCor Partners II L.P., HealthCor Partners Fund II, L.P., HealthCor Partners GP, LLC, Arthur Cohen, Joseph Healey and Jeffrey C. Lightcap. The Original Statement, as amended by this Amendment (the “Statement”) relates to the shares of Common Stock of ReShape Lifesciences Inc., par value $0.01 per share (the “Common Stock”).

Capitalized terms used herein but not defined shall have the meanings ascribed to them in the Original Statement. This Amendment amends the Original Statement as specifically set forth herein. Except as set forth below, all previous Items in the Original Statement remain unchanged.

This Amendment is being filed solely to reflect a decrease in the percentage of the outstanding class represented by the shares of Common Stock owned by the Reporting Persons, resulting from an increase in the number of shares of Common Stock outstanding as reported by the Issuer in its filings with the Securities and Exchange Commission, and the consequent reduction of the Reporting Persons’ beneficial ownership below five percent. There has been no change in the number of shares of Common Stock beneficially owned by the Reporting Persons.

Item 5. Interest in Securities of the Issuer.

The first paragraph of Item 5 of the Original Statement is hereby amended and restated as follows:

“(a) The Reporting Persons beneficially own an aggregate of 349,139 shares of Common Stock. This aggregate amount represents approximately 0.4% of the Issuer’s outstanding common stock, based upon 83,472,628 shares of Common Stock outstanding as of September 27, 2018, as reported on the Issuer’s prospectus supplement filed on October 3, 2018 in connection with the offer and sale of certain equity securities.”

Item 5(e) of the Original Statement is hereby amended and restated as follows:

“(e) To the best of the Reporting Persons’ knowledge, the Reporting Persons ceased to be the beneficial owners of more than five percent of the Issuer’s common stock on or about August 7, 2018.”
