TransMedics Group

TransMedics Group, Inc. (Nasdaq: TMDX) is a medical technology company headquartered in Andover, Massachusetts, focused on advancing organ transplant therapy. The company develops portable organ perfusion systems designed to maintain donor organs in a functioning, near-physiologic state during transport, extending the viability window between organ recovery and transplantation.

The company's flagship product, the Organ Care System (OCS), is a platform of portable devices engineered for heart, lung and liver preservation. Unlike traditional cold-storage methods that place organs in a static, hypothermic state, the OCS maintains organs in a warm, perfused condition that enables real-time assessment of organ function prior to transplantation. This approach allows transplant teams to evaluate organ quality during transport and potentially utilize organs that might otherwise be declined.

TransMedics also operates a national organ retrieval service, combining its OCS technology with logistics coordination to streamline the organ procurement process. The company's integrated approach — pairing preservation technology with retrieval services — addresses systemic bottlenecks in organ transplantation, where time constraints and organ viability remain significant limiting factors in matching available organs with recipients.
