A catheter formed of an elongated shaft (35) with a dilatation balloon (25) at the distal end includes a guide wire lumen (50) external to the balloon (25). The guidewire lumen (50) extends from the distal tip of the catheter (5) to a proximal port distal from the proximal end of the catheter (5). The shaft (35) is formed of a proximal hypotube (90) and a distal spring coil (15). In some embodiments the wire lumen (50) extends the full length of the catheter and includes apertures (75) for drug delivery or perfusion. A core wire (10) is included to enhance the pushability of the catheter and support the balloon (25).
Un cathéter formé d'un manchon allongé (35) et d'un ballonnet gonflable (25) à l'extrémité distale comprend une lumière sur un guide (50) externe par rapport au ballonnet (25). La lumière sur un guide (50) s'étend de l'extrémité distale du cathéter (5) jusqu'à une ouverture proximale éloignée de l'extrémité proximale du cathéter (5). Le manchon (35) est formé d'un hypotube (90) et d'un ressort distal (15). Dans certains spécimens, la lumière sur un guide (50) s'étend sur toute la longueur du cathéter et comporte des ouvertures (75) pour la libération ou la perfusion des médicaments. Un guide central (10) est inclus pour faciliter l'introduction du cathéter et appuyer le ballonnet (25).
