An intravascular catheter such as a dilatation catheter for angioplasty procedures having a removable distal shaft section. The catheter construction allows the original distal shaft section of the catheter to be removed and a replacement distal shaft section to be secured to the proximal section which is useful with angioplasty catheters when the dimensions of the balloon on the original distal shaft section are inappropriate for dilating a particular stenotic region. Such catheter construction is also useful when there is a need to implant a stent into a dilated stenotic region to maintain its patency.

Cathéter intravasculaire tel qu'un cathéter de dilatation pour angioplasties doté d'un tube distal interchangeable. Ce cathéter est conçu de sorte que son tube distal d'origine puisse être enlevé et remplacé par un tube distal de remplacement destiné à être fixé à la partie proximale utilisée avec les cathéters pour angioplastie lorsque la taille du ballonnet sur le tube distal d'origine ne convient pas pour la dilatation d'une région sténotique particulière. Ce cathéter est également utile lorsqu'il est nécessaire d'implanter un extenseur dans une région sténotique dilatée, afin d'en maintenir le passage ouvert.
