PLASTIC COVERED STENT FOR AORTIC DISSECTION AND AORTIC DISSECTION STENT

摘要

A plastic covered stent for aortic dissection and an aortic dissection stent are disclosed. The plastic covered stent for aortic dissection includes a tubular membrane and multiple annular stents sequentially sutured on the membrane along an axial direction. Part of the annular stents on the membrane are semi-suture stents. Each semi-suture stent has non-suture zones separable from the membrane. When the plastic covered stent is bent, the membrane corresponding to the non-suture zones at an inner bending side of the plastic covered stent is separated from the semi-suture stents and folded inwardly. The semi-suture stents are distributed on a bending portion of the plastic covered stent for aortic dissection after being implanted.
