Title (EN) APPARATUS AND METHODS FOR LOW-COST INTRAVASCULAR ULTRASOUND IMAGING AND FOR CROSSING SEVERE VASCULAR OCCLUSIONS

Abstract: front page image
(EN)An intravascular ultrasound catheter system is provided and enables a simplified, economical technique for ultrasound visualization of a blood vessel. The catheter may include a park ablation system for crossing chronic total occlusions and severe stenoses. The catheter is advanceable and is oriented entirely under manual control of the clinician and the application of radiofrequency energy for spark erosion of the stenosis also is controlled manually by the clinician. The system enables the clinician to observe an ultrasound image sufficiently to determine where to orient the ablation electrode so as to reduce the risk of dissection or perforation of the blood vessel. The ultrasound image is generated in response to manual rotation of the catheter and the ablation spark is generated only when the physician is satisfied as to the orientation of the electrode within the vessel.
(FR)L'invention concerne un système de cathéter intravasculaire à ultrasons mettant en oeuvre une technique économique simple de visualisation ultrasonore d'un vaisseau sanguin. Le cathéter peut comporter un système d'ablation par étincelle qui permet de traverser des occlusions totales chroniques et des sténoses graves. Le clinicien peut manuellement faire avancer le cathéter et l'orienter complètement; il peut également commander manuellement l'application d'une énergie radiofréquence pour l'érosion par étincelle de la sténose. Le système permet au clinicien d'observer suffisamment une image ultrasonore pour déterminer l'orientation de l'électrode d'ablation, ce qui permet de réduire le risque de dissection ou de perforation du vaisseau sanguin. L'image ultrasonore est créée en réponse à la rotation manuelle du cathéter et l'ablation par étincelles n'est générée que si le médecin est satisfait par l'orientation de l'électrode à l'intérieur du vaisseau.
