Title
(EN) APPARATUS AND METHOD FOR NERVE ABLATION IN THE WALL OF THE GASTOINTESTINAL TRACT
(FR) APPAREIL ET PROCÉDÉ D'ABLATION DE NERF DANS LA PAROI DU TRACTUS GASTRO-INTESTINAL
Abstract
(EN) Catheter for real-time evaluation of duodenal ablation, the catheter including an expandable member configured to stretch the duodenal wall and to generate a fixed distance between a center of the catheter and the duodenal wall; a laser transmitting element coupled with the catheter body and configured to transmit a first laser beam and a second laser beam; wherein the first laser beam is configured to cause ablative damage in a region of the duodenal wall as a result of its impingement thereon, and wherein the second laser beam is configured to detect modifications in the region of the duodenal wall resulting from the impingement of the first laser beam thereon.
(FR) L'invention concerne un cathéter pour une évaluation en temps réel d'une ablation duodénale, le cathéter comprenant un élément expansible conçu pour étirer la paroi duodénale et pour créer une distance fixe entre un centre du cathéter et la paroi duodénale ; un élément de transmission laser couplé au corps de cathéter et conçu pour transmettre un premier faisceau laser et un second faisceau laser ; le premier faisceau laser étant conçu pour provoquer un dommage ablatif dans une région de la paroi duodénale suite à son impact sur celle-ci, et le second faisceau laser étant conçu pour détecter des modifications dans la région de la paroi duodénale résultant de l'impact du premier faisceau laser sur celle-ci.
