Coated vascular stent

摘要

A coated vascular stent is provided. The coated vascular stent mainly includes a first-layer coating imitating a blood vessel shape, a stent framework attached to the outside of the first-layer coating, and at least a part of the outer surface of the stent framework. And a second layer coating. The first layer coating is bonded to the second layer coating, and at least a portion of the stent framework is encased between the first layer coating and the second layer coating. Here, the coating of the first layer and / or the coating of the second layer is a polyvinylidene fluoride resin coating. Cost can be reduced by using a polyvinylidene fluoride resin coating for the coated vascular stent. In addition, the coating has good mechanical and biological performance.
