A balloon catheter having improved flexibility in and about its distal end is provided. The flexibility of the catheter is determined in part by improving the properties of a wire or catheter located within the area where the balloon is mounted. In one aspect of the present invention, connecting wires extend through the balloon from the distal end of a catheter body to the proximal end of a core wire. The core wire extends distally away from the connecting wires and the catheter body. In another aspect of the present invention, a core wire is provided having a proximal end extending within the balloon into the catheter tubular body but is not mounted therein. This allows the proximal end of the core wire to "float" within the tubular body, such that when the catheter is advanced through the vasculature of a patient, the core wire may move longitudinally within the tubular body. In another aspect of the present invention, the balloon is mounted over a tubular body which is configured to give the catheter longitudinal flexibility.

L'invention concerne un cathéter à ballonnet doté d'une flexibilité améliorée à l'intérieur et autour de son extrémité distale. On détermine en partie la flexibilité du cathéter en améliorant les caractéristiques d'un fil ou d'un cathéter situé dans la zone où est monté le ballonnet. Dans un aspect de la présente invention, des fils de connexion s'étendent dans le ballonnet de l'extrémité distale d'un corps de cathéter à l'extrémité proximale d'un fil de noyau. Le fil de noyau s'éloigne distalement des fils de connexion et du corps de cathéter. Dans un autre aspect de la présente invention, un fil de noyau présente une extrémité proximale s'étendant à l'intérieur du ballonnet dans le corps tubulaire du cathéter mais sans y être fixé, ce qui permet à l'extrémité proximale du fil de noyau de <= flotter >= dans le corps tubulaire, de sorte que lorsque le cathéter avance dans le système vasculaire d'un patient, le fil de noyau se déplace longitudinalement à l'intérieur du corps tubulaire. Dans un autre aspect encore, le ballonnet est monté sur un corps tubulaire configuré de manière à donner au cathéter une flexibilité longitudinale.
