Definitions

  • the guide wire port formed in the rapid exchange type balloon catheter and the manufacturing method thereof have not been sufficiently studied. Furthermore, the guide wire port is used not only for a balloon catheter but also for other types of catheters such as a suction catheter, a penetrating catheter, and a stent delivery catheter, which is a problem common to these catheters.
  • Means 3 has an outer shape formed by thermal welding of the inner tube and the catheter shaft. Since the guide wire port is formed at the time of thermal welding between the inner tube and the catheter shaft, a smooth outer shape of the guide wire port can be realized and the occurrence of burrs can be prevented in advance.
  • a method of heat welding for example, a mold can be used.
  • mid shaft 12 and the proxy shaft 11 are not essential components, and a configuration in which the distal shaft 13 and the proxy shaft 11 are directly connected or a single shaft catheter may be used.
  • the shaft connected to the distal shaft 13 is also called an additional shaft.
  • the guide wire port 30 is formed in the port forming region 13c (length ⁇ 2) that is closer to the distal end 19f than the proximal end 19n of the catheter shaft 19.
  • the guide wire port 30 is formed by the proximal end portion 13 n of the distal shaft 13 and the distal end portion 12 f of the mid shaft 12.
  • the guide wire port 30 is a part of the peripheral wall of the distal shaft that forms the proximal end portion 13n of the distal shaft and one of the peripheral walls of the mid shaft that forms the distal end portion 12f of the mid shaft 12. Part.
  • the fluid lumen mandrel 80 is formed on a part of the side surface of the fluid lumen mandrel 80 so that the inner surface of the fluid lumen lumens 12a and 13a has a crescent-shaped cross-sectional shape.
  • a gentle circular recess 83 is formed.
  • the mandrel for the fluid lumen only needs to have a recess, and the cross-sectional shape is not limited to the crescent shape.
  • the mandrel for the fluid lumen may have a shape in which a recess is formed in a part of a half-moon-shaped straight part, or a shape in which a recess is formed in a part of an ellipse or a quadrangle (may be chamfered). But you can.

Abstract

La présente invention concerne une configuration d'un orifice de fil de guidage d'un cathéter et une technique d'amélioration d'un procédé de production de celui-ci. La présente invention concerne un cathéter à échange rapide qui est guidé par un fil de guidage (G). Le cathéter comprend : une tige de cathéter (12) ayant une extrémité distale et une extrémité proximale ; et un tube interne (14) dans lequel est formée une lumière destinée à insérer le fil de guidage (G), et qui se fixe à la tige de cathéter (12). Un orifice de fil de guidage (G), correspondant à une ouverture destinée à insérer le fil de guidage (G), s'ouvre vers l'extérieur de la tige de cathéter (12), et se forme sur la tige de cathéter (12) au niveau d'une position plus proche de l'extrémité distale que de l'extrémité proximale. L'extrémité proximale de la lumière du tube interne (14) est caractérisée en ce qu'elle est liée à l'orifice du fil de guidage (G) à l'intérieur de la tige de cathéter (12).
