Title
(EN) ULTRASOUND CATHETER
(FR) CATHÉTER ULTRASONORE
Abstract
(EN)
A system and a method for disrupting an occlusion within a blood vessel is provided The system includes an elongated catheter body having a proximal portion, a distal portion, and a first lumen. The system further includes an ultrasound transmitter extending longitudinally through the first lumen of the catheter body and having a proximal end and a distal end. The system further includes a positioning mechanism located at a distal end of the catheter body. The positioning mechanism has a first retracted position and a second deployed position, and the positioning mechanism is radially expandable from the first retracted position to the second deployed position to position the catheter in the blood vessel.
(FR)
L'invention concerne un système et un procédé pour rompre une occlusion à l'intérieur d'un vaisseau sanguin. Le système comprend un corps de cathéter allongé comprenant une partie proximale, une partie distale et une première lumière. Le système comprend en outre un émetteur d'ultrasons s'étendant longitudinalement dans la première lumière du corps du cathéter et comprenant une extrémité proximale et une extrémité distale. Le système comprend en outre un mécanisme de positionnement situé à une extrémité distale du corps de cathéter. Le mécanisme de positionnement a une première position rétractée et une seconde position déployée, et le mécanisme de positionnement est radialement extensible entre la première position rétractée et la seconde position déployée pour positionner le cathéter dans le vaisseau sanguin.
