Claims (13)
- シース(132)と、
該シース内に配置される長尺状の押圧器(134)と、
該押圧器(134)から遠位方向に延びている複数のワイヤ(224、225)と、
該複数のワイヤによって前記押圧器から径方向外方の位置で支持される複数のマーカバンド(228)と、
複数のマーカコイル(106)を有し前記複数のワイヤを覆って放射状に配置されるステントとを含む脈管補綴体送達装置であって、
前記複数のマーカバンド(228)は前記シース(132)内で前記複数のマーカコイル(106)の遠位に位置し、該マーカコイル(106)が該マーカバンド(228)と接触し続けられるように前記ステントの近位端が圧縮されたままであると、長尺状の前記押圧器(134)の後退に起因して、前記マーカバンド(228)の近位端が前記マーカコイル(106)の遠位端と接触し、これによって、前記シース(132)内で前記ステントが近位方向に牽引されることを特徴とする脈管補綴体送達装置。 - 前記複数のワイヤ(224、225)は前記押圧器から離れてしなる請求項1に記載の脈管補綴体送達装置。
- 前記複数のワイヤ(224、225)は弧形に形成されている請求項1に記載の脈管補綴体送達装置。
- 該脈管補綴体送達装置はさらに、前記押圧器(134)の遠位端にX線不透過性マーカバンド(222)を含む請求項1に記載の脈管補綴体送達装置。
- 前記押圧器から遠位方向に延びている複数のワイヤ(224、225)は、2ないし8本のワイヤを含む請求項1に記載の脈管補綴体送達装置。
- 該脈管補綴体送達装置はさらに、前記押圧器を通り抜けて前記押圧器の遠位に延びているコアワイヤ(222)を含む請求項1に記載の脈管補綴体送達装置。
- 前記複数のワイヤは、近位では前記押圧器に接続され、遠位では前記コアワイヤ(222)を覆う遠位接着位置(226)に接続される請求項6に記載の脈管補綴体送達装置。
- 前記遠位接着位置(226)はマーカバンドまたは接合部である請求項7に記載の脈管補綴体送達装置。
- 前記マーカバンド(228)は、補綴体のマーカコイル(106)と接触して前記補綴体が送達シース内に収納されているときには前記補綴体を動かすように構成されている請求項1に記載の脈管補綴体送達装置。
- 前記マーカコイル(228)は、前記補綴体の近位ループ(104)から放射状に突出している請求項9に記載の脈管補綴体送達装置。
- 前記マーカバンドは、前記複数のワイヤの遠位端と面一である請求項1に記載の脈管補綴体送達装置。
- 請求項1に記載の脈管補綴体送達装置と、
前記押圧器によって押圧される補綴体とを含み、該補綴体は放射状に突出しているマーカコイル(106)を有し、
前記複数のワイヤのマーカバンド(228)は、前記補綴体のマーカコイル(106)の遠位にある脈管補綴体送達システム。 - 前記押圧器(134)を後退させると前記マーカバンド(228)は前記マーカコイル(106)と接触して、これによって前記補綴体を後退させる請求項12に記載の脈管補綴体送達システム。
