Description
技術分野
この発明は、血管内疾患の治療のために人または動物の体内に管腔内装置を埋込むための送達システムに関する。この発明は、特に、管腔内装置の対側部分を挿管するための新規なカテーテルシステムを備えた送達システムに関する。
人および動物の身体における血管および脈管などの機能的な管は、弱まったり破裂したりする場合がある。たとえば、大動脈壁が弱まると、結果として動脈瘤が生じる可能性がある。弱まった血管、動脈瘤血管または破裂した血管に対する外科的介入の一例として、血管を置換または治療するためのステントグラフトの使用が挙げられる。ステントグラフトは、1つ以上のステントと組合せて生体適合性材料のチューブから形成されてもよく、これを通じて管腔を維持し得る。ステントは、ステントをグラフト材料に縫い合わせたり、ステントをグラフト材料に埋込んだり、ステントをグラフト材料に接着接合したりする等のさまざまな方法でグラフト材料に取付けられる。
本発明は、血管内疾患の治療のために人または動物の体内に管腔内装置を埋込むための送達システムに関する。特に、この発明は、追加のプロテーゼモジュールを迅速かつ正確に配置するために管腔内装置の対側肢部を有効に挿管するための新規な送達システムを含む送達システムに関する。
送達装置は、カテーテル上に装着されたプロテーゼ装置と、少なくとも部分的にプロテーゼ装置をおおうシースとを含む送達カテーテルを少なくとも備える。送達装置にはさらにスネア(snare)カテーテルが設けられており、スネアカテーテルの内部には、スネア(snare)機構が配置されている。スネアカテーテルは、当該カテーテルの側部にスネア(snare)開口システムを備える。スネア機構は、スネアカテーテルの開口システムを介してループを形成し、装置の遠位端に2つの自由端を有し得る。
特に規定のない限り、この明細書中に用いられる技術的および学術的用語はすべて、この発明が属する技術の当業者に通常理解されるのと同じ意味を有している。
