Title (EN) ENERGY DELIVERY OF CATHETER AND METHOD FOR THE USE THEREOF
(FR) CATHETER DE DISTRIBUTION D'ENERGIE ET SON PROCEDE D'UTILISATION
Abstract:
(EN) A catheter (10) comprising a flexible tube having a proximal portion (12) and a distal portion. The proximal portion comprises a first lumen (12A) and a second lumen (12B) for a guide wire (22). The distal portion has a single lumen. The catheter has a tapered transition portion (13) interconnecting the proximal and distal portions. Coupled to a proximal end of the catheter are means for inserting an ultrasound or optical fiber into the first lumen for transmitting energy through the catheter, and means for inserting the guide wire through the second lumen. The means for inserting permit extension and retraction of the fiber and the guide wire in their respective lumens. The distal portion is sized to a diameter less than that of the proximal portion, and is just large enough to receive one of the guide wire and the fiber but not both.
(FR) L'invention porte sur un cathéter (10) consistant en un tube souple présentant une extrémité proximale (12) et une extrémité distale (14). L'extrémité proximale comporte une première lumière (12A) et une deuxième lumière (12B) pour un fil guide (22). L'extrémité distale comporte une seule lumière. Le cathéter présente une section de transition (13) conique reliant l'extrémité proximale à l'extrémité distale. Reliés à l'extrémité proximale du cathéter se trouvent des moyens permettant de transmettre l'énergie d'une source énergétique via le cathéter, ainsi que des moyens d'introduction du fil guide dans la deuxième lumière. Les moyens d'introduction sont conçus pour permettre l'avance ou le recul de la fibre ou du fil guide dans leurs lumières respectives. L'extrémité distale présente un diamètre inférieur à celui de la partie proximale, et tout juste assez large pour recevoir soit le fil guide, soit la fibre, mais pas les deux.
