Stent and manufacturing method thereof
Abstract
Abstract Translated from Japanese (57)【要約】 【目的】 生体適合性、特に抗血栓性に優れ、再狭窄の 危険の少ないステントを提供すること。 【構成】 弾性線材で構成された管状構造物の内面及び 外面に、四弗化エチレン樹脂多孔質体膜からなる被覆層 が設けられていることを特徴とするステント。弾性線材 で構成された管状構造物の内面及び外面に、四弗化エチ レン樹脂多孔質体の管状膜を配置し、内面側及び外面側 の管状膜相互間を部分的に熱融着させることを特徴とす るステントの製造方法。管状膜相互間を熱可塑性樹脂を 介して部分的に加熱・加圧接着させることを特徴とする ステントの製造方法。 (57) [Abstract] [Purpose] To provide a stent having excellent biocompatibility, particularly antithrombogenicity, and less risk of restenosis. A stent characterized in that a coating layer made of a porous tetrafluoroethylene resin film is provided on the inner and outer surfaces of a tubular structure made of an elastic wire. A tubular membrane of a tetrafluoroethylene resin porous body is placed on the inner and outer surfaces of a tubular structure made of elastic wire, and partial heat fusion between the inner and outer tubular membranes is performed. A method for manufacturing a characteristic stent. A method for producing a stent, characterized in that the tubular membranes are partially bonded together by heating and pressure via a thermoplastic resin.
