Abstract

Abstract Translated from English Un assemblage de cathéter (10) comprend un premier cathéter (12) ayant des extrémités distale (12a) et proximale (12b), et un second cathéter (14) qui peut être placé dans le premier cathéter (12). Le second cathéter (14) possède un diamètre plus petit et est plus flexible que le premier cathéter (12). Le second cathéter (14) peut être placé dans le premier cathéter (12) de sorte que son extrémité distale (14a) peut s'étendre au-delà de l'extrémité distale (12a) du premier cathéter (12). Un ballon expansible ou un dispositif gonflable (16) est fixé sur la surface externe du premier ou du second cathéter (12, 14) à proximité de son extrémité distale (12a, 14a). Lorsque le dispositif gonflable (16) est gonflé il engage de manière étanche les parois intérieures d'un canal (90) dans lequel l'assemblage de cathéter (10) a été introduit. L'assemblage de cathéter (10) peut également comprendre des fibres optiques associées (20, 22, 26) pour voir et enlever ce qui fait obstruction. A catheter assembly (10) includes a first catheter (12) having distal (12a) and proximal (12b) ends, and a second catheter (14) which can be placed in the first catheter (12). The second catheter (14) has a smaller diameter and is more flexible than the first catheter (12). The second catheter (14) can be placed in the first catheter (12) so that its distal end (14a) can extend beyond the distal end (12a) of the first catheter (12). An expandable balloon or an inflatable device (16) is attached to the outer surface of the first or second catheter (12, 14) near its distal end (12a, 14a). When the inflatable device (16) is inflated it sealingly engages the interior walls of a channel (90) into which the catheter assembly (10) has been introduced. The catheter assembly (10) can also include associated optical fibers (20, 22, 26) for viewing and removing obstructions.
