TransMedics

TransMedics Group, Inc. is a medical technology company headquartered in Andover, Massachusetts, specializing in organ preservation and transplantation. The company manufactures the Organ Care System (OCS)—an FDA-approved, portable ex vivo perfusion platform that maintains donor organs in a near-physiologic state outside the body. TransMedics offers specialized OCS systems for lung, heart, and liver transplantation, addressing critical limitations of traditional cold storage by reducing ischemic injury, improving organ viability assessment, and enabling long-distance organ retrieval. The company also operates the National OCS Program (NOP), providing comprehensive end-to-end technology and clinical support services to transplant centers, including organ procurement logistics, clinical expertise, and resource optimization. Founded in 1998, TransMedics went public in 2019 and has established itself as a leader in transforming transplant outcomes for patients with end-stage organ failure.
