Description
本出願は2008年6月4日に出願した米国仮出願第61/058,770号の優先権を主張する。
発明の分野
本発明は、一般に、身体通路内に保留されるデバイスに関し、1つの特定の用途において、動脈拡張症、たとえば、動脈瘤を修復するのに使用される脈管デバイスに関する。より詳細には、本発明は、展開の際に調節でき、そのため、デバイスを長手方向又は半径方向の少なくともいずれかの方向で再配置することができるデバイスに関する。
本発明は、一般に、腹部大動脈中の二股ステントグラフトの展開に関して議論されるが、それに限定されず、他の身体管腔中のデバイス展開に応用できる。ステントグラフトを腔内法又は血管内法により輸送する際に、脈管構造内におけるデバイスの正確な位置を知ることは重要である。この正確な位置を制御することは、分岐血管に近接して又は大動脈壁の弱くなった部分に隣接してデバイスを展開しようとする際には特に重要である。大動脈瘤を修復するために使用される典型的なステントグラフトはステントグラフトの長手方向の移動を制限することを目的とする近位(心臓に最も近いステントグラフトの部位)係留装置を含む。しばしば、この係留装置は分岐血管の閉塞を避け又は大動脈壁の不全及び損傷部位内の配置をさけるために、正確に配置されなければならない。
本発明は、関連技術の制約及び欠点による問題点の1つ以上を実質的に取り除く制御展開可能な医療デバイス及びその製造方法に関する。
添付の図面は本発明のさらなる理解を提供しそして本発明の特定の態様を例示するために含まれる。図面中、
本発明は、一般に、身体通路内に保留されうるデバイスを含む新規の医療装置に関し、1つの特定の用途において、脈管デバイスに関する。より詳細には、本発明は、展開の際に調節でき、そのため、デバイスを長手方向又は半径方向の少なくともいずれかの方向で再配置することができるデバイスに関する。本明細書で使用される際に、用語「遠位」とは、心臓から最も遠い位置を意味し、一方、用語「近位」とは心臓に最も近い位置を意味する。
