(摘要)
ステントを体腔内で展開するための方法、装置、及びシステムが記載される。ステント送達システムは、第1の材料から作製される部分的に管状の第1の部分と、第1の部分に接着されて管状本体を形成する第2の材料から作製される第2の部分と、を有するシースを含んでもよい。場合によっては、第1の材料は、第1の部分と第2の部分との間の接着が架橋結合を含まないように、第2の材料と化学的に不適合であってもよい。本ステント送達システムは、シース内に摺動可能に配設され得る遠位先端を有するガイドワイヤ内腔と、ガイドワイヤ内腔とシースの内面との間に配設された管状ステントと、を更に含んでもよい。シースは、第1の材料及び第2の材料を共押出して、シースのストライプ管状本体を形成することによって形成されてもよい。
語句によって始まる項目のリスト)内で使用される時の「又は(or)」は、包括的リストを指示する。そのため、例えば、A、B、又はCのうちの少なくとも1つのリストは、A又はB又はC又はAB又はAC又はBC又はABC(即ち、AかつBかつC)を意味する。
特性が少なくとも1つの実施形態に含まれることを意味する。それゆえ、本明細書全体を通じた様々な箇所における語句「一実施形態では(in one embodiment)」又は「一実
施形態では(in an embodiment)」の出現は必ずしも全て、同じ実施形態に言及しているわけではない。更に、特定の特徴、構造、又は特性は1つ以上の実施形態において任意の好適な様態で組み合わせられ得る。
