A medical balloon catheter, characterized in that groove parts and/or projected parts spirally formed relative to the major axis of a balloon are formed in and/or on the balloon. By this structure, even after the balloon is temporarily expanded, for example, when the catheter is pushed into a high constriction degree of a lesion region having a diameter smaller than the contracted shape of the balloon or taken out after passing the lesion region, the catheter can be further wound easily to reduce a push-in resistance.
L'invention concerne un cathéter à ballonnet médical caractérisé en ce que des parties de rainure et/ou des parties saillantes formées par rapport à l'axe principal d'un ballonnet sont formées dans et/ou sur le ballonnet. Selon l'invention, même après la dilatation temporaire du ballonnet, par exemple, lorsque le cathéter est poussé dans une zone de constriction élevée d'une région lésée présentant un diamètre inférieur à la forme contractée du ballonnet ou retiré après avoir passé la région lésée, cette structure permet de réenrouler facilement le cathéter en vue d'une réduction de la résistance à la poussée.
