Title (EN) APPARATUS AND METHOD FOR AN ULTRASONIC MEDICAL DEVICE WITH A NON-COMPLIANT BALLOON
(FR) APPAREIL ET METHODE POUR DISPOSITIF MEDICAL A ULTRASONS POURVU D'UN BALLONNET NON SOUPLE
Abstract:
(EN) The present invention provides an apparatus and a method for an ultrasonic medical device (11) with a non-compliant balloon (41) used to ablate a biological material. The ultrasonic medical device (11)comprises an ultrasonic probe (15), a catheter (36) surrounding the ultrasonic probe (15), a balloon (41) supported by the catheter (36) and an inflation lumen (85) located along a longitudinal axis of the catheter (36). The ultrasonic probe (15) is inserted into a vasculature (44) and the catheter (36) comprising the balloon (41) is advanced until the balloon (41) is adjacent to the biological material. The balloon (41) is inflated until at least a portion of an outer surface (53) of the balloon (41) engages the biological material. The ultrasonic probe (15) is energized to produce a transverse ultrasonic vibration that vibrates at least a portion of the balloon (41) to ablate the biological material into a particulate.
(FR) La présente invention concerne un appareil et une méthode destinés à un dispositif médical à ultrasons (11) pourvu d'un ballonnet non souple (41) et permettant d'ablater une matière biologique. Ce dispositif médical à ultrasons (11) comprend une sonde à ultrasons (15), un cathéter (36) entourant cette sonde à ultrasons (15), un ballonnet (41) supporté par le cathéter (36) et une lumière de gonflement (85) longeant un axe longitudinal du cathéter (36). La sonde à ultrasons (15) est insérée dans un système vasculaire (44) et le cathéter (36) comprenant le ballonnet (41) est avancé jusqu'à ce que le ballonnet (41) soit adjacent à la matière biologique. Ce ballonnet (41) est gonflé jusqu'à ce qu'une partie au moins d'une surface extérieure (53) du ballonnet (41) entre en contact avec la matière biologique. La sonde à ultrasons (15) est alimentée en énergie en vue de la production d'une vibration ultrasonore transversale faisant vibrer une partie au moins du ballonnet (41) de manière à ablater la matière biologique en une matière particulaire.
