A connector (14) for attaching an ultrasound transducer (12) to an ultrasound catheter (10) has a support member formed on the ultrasound transducer for supporting at least a portion of a catheter coupling (16) which is disposed at the proximal end of ultrasound catheter. The support member preferably comprises a collar (50) slideably disposed upon the ultrasound transducer so as to move from a non-supporting position wherein the collar is disposed adjacent the catheter coupling to a supporting position wherein the collar is disposed around and engages the catheter coupling. Supporting at least a portion of the catheter coupling mitigates the occurrence of ultrasound transmission member breakage by reducing mechanical stress applied to the proximal end thereof.
Un connecteur (14) permet de fixer un transducteur à ultrasons (12) à un cathéter à ultrasons (10). Il comporte un support situé sur le transducteur à ultrasons et supportant au moins une partie d'un coupleur de cathéter disposé à l'extrémité proximale du cathéter à ultrasons. Ce support comprend de préférence un collier (50), disposé de façon à pouvoir coulisser sur le transducteur à ultrasons pour passer d'une position non porteuse, où ledit collier est adjacent au coupleur de cathéter, à une position porteuse où il est disposé autour du coupleur de cathéter et en prise avec lui. Le fait de supporter une partie au moins du coupleur de cathéter limite les risques de rupture de l'élément de transmission des ultrasons en limitant les contraintes mécaniques appliquées à son extrémité proximale.
