Abstract
【解決手段】このキットは外筒カテーテルと呼ばれる第1カテーテル(1)と、この外筒カテーテルに挿入可能なロッドとを具え、このロッドは、その先端にロッドから外に広がって自然に散開した内側に曲がったフック(20)を有するた複数の弾性分枝(18)を具え、これらが互いに閉じることによってフィルタの前端(31)を把持するように構成され、更に好ましくは、このキットは外筒カテーテル(1)内に挿入可能な直径を有する第2カテーテル(11)も具えている。
【選択図】図2
Description
第1の「外筒」カテーテルと、
前記外筒カテーテルに挿入可能で、一端に多数の可撓性のレッグを有するステムであって、そのレッグは、ステムから外へ開いていて、自然に散開し、かつ内側に向いたフックで終わっており、そのフックは、そのレッグが再び閉じた場合にフィルタのブッシュを把持するようになっているところのステムと、
から構成されていることを特徴とするキットに関する。
ステムとそのフック付きのレッグはステンレス製であることが望ましい。ハンドルが付いている場合には、そのハンドルも例えばポリエチレン製であることが好ましい。
図1には、面取りされた前端3を具えた内径3.0mm(9F)のポリエチレン製の中空チューブ2で構成された「外筒 (external) 」と呼ばれる第1カテーテル1が示されている。その後端には操作を容易にするように太くなった部分4が設けられ、フランジ5で終わっている。必要に応じて、前端3には、体外から検出可能なリング状の放射線不透過ゾーンが設けられている。その長さL1は550mmである。
