Description
選択的な実施態様の長さと、幅と、他の寸法機能と同様に、基部脚126jと末部脚125jの数の変化は、回収バスケットの業者には明らかであろう。
この実施態様において、バスケットの脚125oの末端部155oは、安定化棒180oの末端部に取付けられる。いくつかの実施態様において、コネクタ164oは、脚125oを安定化棒180oに接続する。コネクタ164oは、圧接リングなどいずれかの従来連結手段である。
内腔306wは、例えば結石、あるいはポリープ、あるいは他の類似物体付近の患者の体内の場所など患者の体内の処理サイトへ流体を配送し及び/又は処理サイトから流体を除去するに有用である。内腔306wは同様に、誘導ワイアを受容するよう大きさを決められまた成形される(示されていない)。したがって、いくつかの実施態様において、装置は誘導ワイアを超えて処理サイトに移動する。
