The Organ Preservation ecosystem comprises a tightly coupled sequence of upstream, midstream, and downstream activities that together enable viable grafts from donor to recipient. Upstream, raw material and component suppliers provide preservation solutions, perfusion fluids, and specialized containers. Midstream actors—technology providers, OEM manufacturers, and system integrators—assemble and qualify devices such as hypothermic machines, normothermic perfusion platforms, and monitoring software. Downstream, distributors, service firms, and regulatory bodies channel approved systems to transplant centers, where surgeons and organ procurement organizations execute the final preservation and transplantation steps. Value is generated through the conversion of scientific preservation methods into commercial hardware and consumables, captured by manufacturers and service contracts, while end‑users derive clinical benefit from extended organ viability.
