Definitions

  • the detent portion 112 serves as an anchor that fixes the position at a predetermined distance from the distal end of the second operation wire 42. Function.
  • the curvature radius of the curved catheter 2 is different between the distal side and the proximal side from the wire fastening member 100 as the restraining member, and the curvature radius of the catheter 2 proximal to the wire fastening member 100 is different from the wire fastening member 100. It becomes smaller than the radius of curvature of the more distal catheter 2. Therefore, the variation of the curve shape of the catheter tip can be further increased, and as a result, the operability of the catheter 2 can be further improved.

Abstract

La présente invention concerne un cathéter (2) comprenant : un composant tubulaire flexible (4) avec une pluralité de lumières formées le long de l'axe de celui-ci ; un premier câble de commande (40) inséré dans une première lumière, qui est l'une de la pluralité de lumières mentionnées ci-dessus ; et un deuxième câble de commande (42) inséré dans une deuxième lumière, qui est une autre de la pluralité de lumières mentionnées ci-dessus. Le composant tubulaire (4) se courbe dans une première direction lorsque le premier câble de commande (40) est tiré et se courbe dans une deuxième direction lorsque le deuxième câble de commande (42) est tiré. Au moins des parties de la région courbée (N) formée lorsque le composant tubulaire se courbe dans la première direction et la région courbée (M) formée lorsque le composant tubulaire se courbe dans la deuxième direction sont décalées le long de l'axe du composant tubulaire (4). Lorsque le composant tubulaire se courbe dans la première direction, une région rectiligne (O) d'une longueur prescrite est formée de l'extrémité distale du composant tubulaire (4), et la région courbée mentionnée ci-dessus (N) est formée en position proximale à ladite région rectiligne (O).
