Summary:A catheter (102), comprising: a catheter shaft (212) having a fluid channel (420), an ultrasound transducer (214) and a compliant balloon (108) mounted on the catheter shaft (212) and having an interior (504) in fluid communication with the fluid channel (420) and containing the ultrasound transducer (214). The compliant balloon (108) includes a balloon wall (502) having a working section (1600) radially surrounding the ultrasound transducer (214), a proximal shoulder (510B) proximal to the working section (1600), and a distal shoulder (510A) distal to the working section (1600). The balloon wall (502) is thicker at the proximal shoulder (510B) and the distal shoulder (510A) than at the working section (1600). L'invention concerne un cathéter (102), comprenant : une tige de cathéter (212) ayant un canal de fluide (420), un transducteur ultrasonore (214) et un ballonnet souple (108) monté sur la tige de cathéter (212) et ayant un intérieur (504) en communication fluidique avec le canal de fluide (420) et contenant le transducteur ultrasonore (214). Le ballonnet souple (108) comprend une paroi de ballonnet (502) ayant une section de travail (1600) entourant radialement le transducteur ultrasonore (214), un épaulement proximal (510B) proximal par rapport à la section de travail (1600), et un épaulement distal (510A) distal par rapport à la section de travail (1600). La paroi de ballonnet (502) est plus épaisse au niveau de l'épaulement proximal (510B) et de l'épaulement distal (510A) qu'au niveau de la section de travail (1600).
