Abstract:
A Catheter Based Heart Valve (CBHV) is described herein which replaces a non functional, natural heart valve. The CBHV significantly reduces the invasiveness of the implantation procedure by being inserted with a catheter as opposed to open heart surgery. Additionally, the CBHV is coated with a biocompatible material to reduce the thrombogenic effects and to increase durability of the CBHV. The CBHV includes a stent and two or more polymer leaflets sewn to the stent. The stent is a wire assembly coated with Polystyrene-Polyisobutylene-Polystyrene (SIBS). The leaflets are made from a polyester weave as a core material and are coated with SIBS before being sewn to the stent. Other biocompatible materials may be used, such as stainless steel, Titanium, Nickel-Titanium alloys, etc.
