Title:
自己拡張性ステント移植片を作成するための方法
Document Type and Number:
Japanese Patent JP4916616
Kind Code:
B2
Abstract:
In accordance with the present invention, there is provided a method of making a stent-graft for insertion into target site within a vessel of a patient. The graft has a crimped state for delivery to the target site, and an expanded state for implantation therein. The method uses a self-expanding tubular elastic outer stent having a crimped and expanded state, and includes the step of expanding the outer stent to its expanded state. The method also uses a tubular flexible porous graft member and includes the step of inserting the graft member along an interior of the outer stent. The method also uses a self-expanding tubular elastic inner stent, and includes the step of crimping the outer stent to a diameter smaller than a diameter of the expanded outer stent. The method then continues by inserting the inner stent within an interior of the graft member, and expanding the inner stent such that the inner stent, the graft member and the outer stent are all abutting.
