Title
(EN) BALLOON CATHETER HAVING AN OSCILLATING TIP CONFIGURATION
(FR) CATHETER A BALLONNET AYANT UNE POINTE OSCILLANTE
Abstract
(EN)
A catheter is disclosed which includes an over-the-wire type balloon catheter, with a guide wire, wherein the catheter incorporates an axially movable inner tubular member which extends proximally through a proximal manifold lumen. The inner tubular member extends distally beyond the distal end of the outer tubular member with the balloon member distal waist affixed to the inner tubular member proximate the distal end. The catheter incorporates axial tension members which function to transmit force to the distal tip when the movable inner tubular member is oscillated axially. The axial tension members are preferably a plurality of wires, each having a proximal end affixed to the outside diameter of the inner tubular member proximate the manifold, and each having a distal end affixed to the outside diameter of the inner tubular member a substantial distance distal of the manifold. When the inner tubular member is pulled proximally, energy is stored in the catheter, which when the inner is released, forces the distal tip forward with added force from the distal point of attachment of the axial tension members. An actuator and a valve assembly are preferably included.

L'invention concerne un cathéter comprenant un cathéter à ballonnet sur fil, présnetant un fil-guide. Ce cathéter comporte aussi un élément tubulaire intérieur se déplaçant de manière axiale et s'étendant de manière proximale à travers une lumière proximale. L'élément tubulaire intérieur s'étend distalement au-delà de l'extrémité distale de l'élément tubulaire extérieur, la ceinture distale du ballonnet étant fixée à l'élément tubulaire intérieur à proximité de l'extrémité distale. Le cathéter comprend encore des éléments de tension axiale servant à transmettre la force vers la pointe distale lorsque l'élément tubulaire intérieur mobile oscille axialement. Les éléments de tension axiale sont constitués, de préférence, d'une pluralité de fils, chacun ayant une extrémité proximale adjacente au diamètre extérieur de l'élément tubulaire intérieur à proximité du collecteur et chacun présentant une extrémité distale adjacente au diamètre extérieur de l'élément tubulaire intérieur à une distance considérable du collecteur. Lorsque l'élément tubulaire est tiré de manière proximale, l'énergie est stockée dans le cathéter qui, une fois l'intérieur relâché, pousse l'embout distal vers l'avant avec une force ajoutée à partir du point distal de fixation des éléments de tension axiale. On prévoit de préférence un dispositif d'actionnement et une soupape.
