TransMedics Group, Inc. focuses on transforming organ transplant therapy for patients with end-stage lung, heart, and liver failure. Its core product, the Organ Care System (OCS), is a portable medical device that maintains donor organs in a warm, functioning state during transport, allowing surgeons to assess organ viability prior to transplantation. In addition to manufacturing the OCS consoles and single-use disposable sets, the company operates the National OCS Program (NOP). The NOP is a turnkey service providing outsourced organ procurement, perfusion management, and transplant logistics, supported by the company's own dedicated aviation fleet. By vertically integrating clinical support and transportation, TransMedics aims to increase the utilization of donor organs and improve transplant outcomes across the United States and internationally.
