The registry is a prospective, multicenter, single arm post-market real-world registry in China assessing the clinical use, safety and outcomes of the Orchid 035 DCB Catheter in the Superficial Femoral Artery (SFA) and Popliteal Arteries (PA).

PTA is an established alternative to open surgical bypass for the treatment of infrainginual disease of critical limb ischemia.

DEBs are designed to promote arterial patency by reducing neointimal proliferation.
