Significance of Peripheral Drug-Eluding Stent System

This product is suitable for percutaneous angioplasty in patients with femoral and popliteal artery (except for the subgenicular artery) stenosis or occlusion. The product dilates through balloon compression, mechanically dilating the narrow area of the blood vessel.

At the same time, the rapid release of paclitaxel in the drug coating inhibited intimal hyperplasia. This product is expected to improve the long-term patency rate of target vessels and improve the quality of life of patients.
