Abstract
Description
例示的一実施形態は、内部に閉塞を有する血管を再開通させるためのカテーテルである。カテーテルは、基端部と、先端部と、先端部に近接した先端部分とを有するカテーテルシャフトを含む。カテーテルはまた、カテーテルシャフトの先端部分に結合した拡張可能部材を含む。可撓性チューブ部材は、カテーテルシャフトからかつ拡張可能部材の外側に沿って延在する。拡張可能部材の拡張によって、可撓性チューブ部材は、カテーテルシャフトの長手方向軸から離れるように撓んだ形態になる。
本開示の態様は、添付の図面と併せて、以下の様々な実施形態の詳細な説明を考慮するとより完全に理解され得る。
本明細書の全ての数値は、明確に示すか否かに関わらず、用語「約」によって修正されると考えられる。用語「約」は、一般的に、当業者が、引用した値に等価であるとみなす(すなわち、同じ機能または結果を有する)、ある範囲の数を指す。多くの場合、用語「約」は、有効数字に丸められる数を含むことを示す。
様々な構成要素、特徴および/または仕様に関するいくつかの好適な寸法、範囲および/または値が開示されるが、本開示を実施しようとする当業者は、所望の寸法、範囲および/または値が、それらの明白に開示されたものからずれ得ることを理解する。
