The types segment categorises grafts by biological origin and material composition, each influencing clinical outcomes and cost structures. Autologous grafts dominate the market, representing over 70% of total volume; within this class, the saphenous vein graft (SVG) is the most widely used due to ease of harvest, while internal mammary artery (IMA) and radial artery grafts are preferred for their superior long‑term patency, especially in high‑risk patients. Allogenic grafts, chiefly cryopreserved arterial conduits, occupy roughly 15% of the market, offering an alternative when autologous vessels are unsuitable, but they incur higher processing and storage expenses. Synthetic grafts, such as polytetrafluoroethylene (PTFE) conduits, make up the remaining 15%, primarily serving patients with extensive peripheral vascular disease or those requiring off‑the‑shelf solutions. This taxonomy underscores how each graft type contributes to overall market revenue through distinct adoption rates, pricing tiers, and clinical performance profiles.
