Abstract
【解決手段】患者の冠状静脈洞などの血管から採血するカテーテルは、細長く柔軟なチューブと、チューブの遠位端部から距離をおいた環状シール部材を有する。チューブの近位端部は吸引力源と接続され、その吸引力がチューブの採取内腔にかけられる。遠位端部は、シール部材とともに血管内に挿入され、採取内腔に吸引力がかけられていないときは、シール部材は、血管の対向面から離れている。流体流入口を通って血管から採取内腔に血液を引き込むのに充分であって、かつ、血管の対向面がシール部材に向かって移動し、シール状態になるのに充分な大きさの吸引力が採取内腔にかけられる。
【選択図】図1A
Description
本発明の好ましい一実施形態によれば、患者の(冠状静脈洞のような)血管から流体を採取する方法及び装置が開示される。当該方法は、遠位端部まで伸びる細く柔軟なチューブ部を有する採取部材をカテーテルとして使用することを含む。環状シール部材(好ましい一実施形態においては、例えば、膨張可能バルーン)が、遠位端部から間隔をあけてチューブ部材に固定されている。チューブ部の内腔は、シール部材より遠位にある1つの流体吸入口を有する。チューブ部材の近位端部は、吸引力を採取内腔に及ぼすための吸引源に接続されるようになっている。当該方法は、血液が遠位端部からシール部材へ向かう方法に順行する血管中に遠位端部を挿入することを含む。採取内腔に吸引力が及ばない状態では、シール部材は、対向する血管の内面からは離れている。流体吸引口を通って血管から採取内腔に血液を取り込むのに充分であって、さらに、対向する血管の内面をシール部材の方向に移動させ、血管を塞ぐのに充分な吸引力が採取内腔に及ぶ。
同一要素には同一番号を振ったいくつかの図を参照しつつ、本発明の好ましい実施形態を以降に説明する。
