Claims (5)

カテーテル本体と、該カテーテル本体の遠位部に設けられ該カテーテル本体を通じて流体が注入されることにより拡径するバルーンとを有するバルーンカテーテルであって、
前記バルーンは、前記カテーテル本体を周回しながら該カテーテル本体の長手方向に延びる、周回方向両側の部分と比較して相対的に性状が異なる螺旋形の筋を有することを特徴とするバルーンカテーテル。 A balloon catheter having a catheter body and a balloon that is provided at a distal portion of the catheter body and expands its diameter when fluid is injected through the catheter body,
The balloon catheter has a spiral muscle having a relatively different property compared to the portions on both sides in the circumferential direction, extending in the longitudinal direction of the catheter body while circling the catheter body. 前記筋が、前記バルーンの前記周回方向に等間隔に離れた複数箇所に形成されていることを特徴とする請求項１記載のバルーンカテーテル。   2. The balloon catheter according to claim 1, wherein the muscles are formed at a plurality of locations spaced at equal intervals in the circumferential direction of the balloon. 前記筋は、前記バルーンを形づくる第１の材料からなる膜に、該第１の材料とは剛性が異なる第２の材料からなる螺旋形の筋が、該膜の両面のうちの一方または双方の面への露出を許容して、埋め込まれることにより形成された筋であることを特徴とする請求項１または２に記載のバルーンカテーテル。   The muscle is formed on a film made of a first material forming the balloon, and a spiral line made of a second material having a rigidity different from that of the first material is formed on one or both of the surfaces of the film. The balloon catheter according to claim 1, wherein the balloon catheter is a muscle formed by being implanted while allowing exposure to a surface. 前記筋が、該筋の前記周回方向両側の部分と比較して相対的に剛性が高い筋であることを特徴とする請求項２または３に記載のバルーンカテーテル。 The balloon catheter according to claim 2 or 3 , wherein the muscle is a muscle having relatively high rigidity as compared with portions on both sides of the muscle in the circumferential direction. カテーテル本体の遠位部に設けられ該カテーテル本体を通じて流体が注入されることにより拡径するバルーンであって、
前記カテーテル本体を周回しながら該カテーテル本体の長手方向に延びる、周回方向両側の部分と比較して相対的に性状が異なる螺旋形の筋を有することを特徴とするバルーン。 A balloon which is provided at a distal portion of the catheter body and expands its diameter when fluid is injected through the catheter body,
A balloon having helical muscles extending in the longitudinal direction of the catheter body while circling the catheter body and having relatively different properties compared to the portions on both sides of the circumference of the catheter body.
