Abstract
【解決手段】第1の管部材18及び第2の管部材22はそれぞれ独立して形成されるか、または異なる材料により形成される。カテーテルの軸12の先端部とバルーン14が結合されており、バルーン14は第2の内腔22と流体により連結されている。柔軟性を制御する部材26は第1の管部材18及び第2の管部材22と結合され、これらと同一方向に延びることが許容される。
【選択図】 図1
Description
本発明の一態様に基づきカテーテルの軸を形成するために、第1の内腔を形成する第1の管部材及び第1の管部材の外周面と結合し、これと同一方向に延び、第2の内腔を形成する第2の管部材を有する。第1及び第2の管部材はそれぞれ独立して形成される。第1の内腔と流体により連結されているカテーテルの軸の先端部に対しバルーンが結合される。
柔軟性制御部材は、その先端部における小径部に向かってテーパーが付けられていることが好ましい。
柔軟性制御部材はその先端部が前記バルーンの中で終わるように設けられてもよい。
第1及び第2の管部材が互いに分離解放可能に結合されていることが好ましい。
