Coronary Artery Bypass Graft (CABG) market taxonomy by type distinguishes conduit choice rather than surgical technique, determining procurement budgets and long-term outcomes. Saphenous vein grafts still claim 55 % unit utilization because of abundant length and ease of harvesting, yet their ten-year patency near 50 % drives repeat procedures, sustaining downstream demand for endoscopic harvest systems and closure devices. Internal thoracic artery utilization, mandated in guidelines, approaches 90 % of cases but translates to 30 % of total graft length; its superior patency lowers repeat revascularization, indirectly moderating overall market growth. Other arterial conduitsโradial, right gastroepiploic, inferior epigastricโconstitute <10 %, limited by harvest complexity and operator learning curve, although radial use is rising in bilateral ITA programs seeking improved late survival.
