Title (EN) COOLING SYSTEM FOR ULTRASOUND DEVICE
(FR) SYSTEME DE REFROIDISSEMENT POUR DISPOSITIF A ULTRASONS
Abstract:
(EN) This invention is an ultrasound treatment system, and method for utilizing ultrasound to treat stenotic and occluded regions of blood vessels comprising an energy source (815), an ultrasound probe (200) for applying ultrasound energy to a treatment site that includes at least one transmission member (A), a passageway (245) communicating with the transmission member of the ultrasound probe (200), a fluid delivery system that includes a drive mechanism (36), a pusher block (34) for being driven by the drive mechanism, a syringe (50) for supplying fluid to the passageway (245) to cool the ultrasound probe (200), and a locking mechanism (150) for preventing the pusher block (34) from disengaging from the drive mechanism during operation.
(FR) L'invention concerne un système de traitement par ultrasons, ainsi qu'un procédé d'utilisation d'ultrasons pour traiter les régions sténosées et obstruées de vaisseaux sanguins. Ce système comprend: une source d'énergie (815), une sonde ultrasonore (200), permettant d'appliquer de l'énergie ultrasonore sur le site du traitement, cette sonde étant pourvue d'au moins un élément de transmission (A), un passage (245) communiquant avec ledit élément de transmission de la sonde (200), un système d'alimentation de fluide comprenant un mécanisme d'entraînement (36), une bloc-poussoir (34) destiné à être entraîné par ce mécanisme d'entraînement, une seringue (50) qui alimente ledit passage (245) en fluide afin de refroidir la sonde ultrasonore (200), et un mécanisme de verrouillage (150) conçu pour empêcher ledit bloc-poussoir (34) de se détacher du mécanisme d'entraînement en cours de fonctionnement.
