PROBLEM TO BE SOLVED: To provide an EVAR delivery system that minimizes compressive forces on the prosthesis and provides smooth delivery and accurate positioning of the prosthesis in the vasculature.SOLUTION: The delivery system includes a primary elongated member positioned coaxially within the prosthesis. A secondary elongated member surrounds a portion of the primary elongated member and a portion of the secondary elongated member is positioned coaxially within the prosthesis. The delivery system further includes a proximal anchor attached to the secondary elongated member. The anchor is adapted for engagement with the proximal end of the prosthesis, thereby maintaining the prosthesis in its radially compressed configuration. At least one outer sheath is adapted to be retracted to expose the prosthesis while the prosthesis is maintained in its radially compressed configuration. The primary elongated member and the secondary elongated member are axially movable relative to one another to disengage the prosthesis from the anchor and permit expansion of the radially compressed prosthesis.COPYRIGHT: (C)2013,JPO&INPIT【課題】補綴器具にかかる圧縮力を最小化して、スムーズな送達と血管内での正確な位置決めできるEVAR送達システムの提供。【解決手段】送達システムは、補綴器具の内部に同軸上に位置する、第一の細長い部材を備える。第二の細長い部材は、第一の細長い部材の一部分を取り囲み、第二の細長い部材の一部分は、補綴器具の内部に同軸上に位置する。送達システムは、さらに、第二の細長い部材に取り付けられた、近端部アンカを備える。アンカは、補綴器具の近端部と係合されて、補綴器具を径方向に圧縮される構成を維持する。補綴器具が径方向に圧縮される構成に維持されている間に、少なくとも1つの外側の鞘は、引っ込んで補綴器具を露出するようにされている。第一の細長い部材、及び、第二の細長い部材は、互いに軸方向に動くことができ、アンカから補綴器具の係合を解いて径方向に圧縮された補綴器具は膨張できる。【選択図】図1A
