The Veno-Venous Extracorporeal Life Support (VV ECLS) Devices ecosystem spans three functional layers. Upstream, raw‑material and component suppliers provide medical‑grade polymers, membranes, and electronic sub‑assemblies that meet stringent biocompatibility standards. Midstream actors—OEM manufacturers, technology licensors, and system integrators—assemble these inputs into complete VV ECLS platforms, embed monitoring software, and certify performance against regulatory benchmarks. Downstream, distributors, service firms, and clinical buyers (hospitals, specialized ECMO centers) deliver the finished systems, support installation, and manage post‑sale maintenance. Value is created through the conversion of high‑precision components into clinically certified devices and captured via device sales, service contracts, and data‑driven performance analytics.
