Abstract
Description
本発明の他の形態の、患者のルーメン内配置されその中で互いに結合する少なくとも第1と第2の部材を有する2部品ステントグラフトプロテーゼ組み立て体において、前記一方の部材は、前記ルーメン内に最初に配置され拡張され、前記一方の部材は、ステントグラフトプロテーゼの内側表面に1つあるいは複数のステントを具備した第1端部を有し、前記他方の部材は、前記ルーメン内にその後に配置され拡張され、前記第1端部内に配置される第2端部を有し、前記第2端部は、その内側表面に1つあるいは複数のステントを具備するグラフト部分を有し、前記第1端部及び第2端部が、互いに係合したときに、係合部分の間にステントが存在しないような円筒状領域が存在する。
本発明の一実施例においては、合成プロテーゼは、腹部大動脈あるいは腸骨動脈の瘤を治療するために、その血管の瘤部分を動脈の血液の流れと圧力から切り離すことにより治療するためのものである。本発明の合成プロテーゼは、複数の部品からなる装置で、装置の全長を「トロンボーン方式」で変化させることを外科医ができるような症例で用いられる。あるいはネックの角度の増加が必要とされるようなアプリケーションで用いられる。本発明の装置は、外科手術により大腿動脈内に挿入され、この装置が脈管内貫通技術を用いて剛性のあるワイヤガイドを通して所望の場所まで進められる。脈管内のグラフトの長さと直径の広い範囲が、個々の患者に対するために外科医に提供される。
