Title
(EN) MULTIPLE-CHAMBERED BALLOON CATHETER FOR FLARING INSTALLED STENTS
(FR) CATHÉTER À BALLONNETS À CHAMBRES MULTIPLES POUR ÉVASEMENT DE STENTS INSTALLÉS
Abstract
(EN)
Multiple-chambered balloon catheters configured to releasably engage and shape stents previously installed in subjects, kits comprising multiple-chambered balloon catheters, methods for production of multiple-chambered balloon catheters, and methods for the use of multiple- chambered balloon catheters to releasably engage and shape previously installed vascular stents are provided. The multiple-chambered balloon catheter comprises a catheter shaft provided with a distal tip suitably configured for navigating vascular systems, and is further provided with at least two chambered balloons sealably engaged with the catheter shaft wherein the first balloon is positioned approximate the distal tip of the catheter shaft, and the at least second balloon is positioned adjacent the first balloon. At least two reference markers are provided on the catheter shaft underlying at least one of balloons.

L'invention porte sur des cathéters à ballonnets à chambres multiples configurés pour mettre en prise de façon libérable et mettre en forme des stents préalablement installés sur des sujets, sur des kits comprenant des cathéters à ballonnets à chambres multiples, sur des procédés de fabrication de cathéters à ballonnets à chambres multiples et sur des procédés d'utilisation des cathéters à ballonnets à chambres multiples afin de mettre en prise de façon libérable et de mettre en forme des stents vasculaires préalablement installés. Le cathéter à ballonnets à chambres multiples comprend un arbre de cathéter comportant un embout distal configuré de façon appropriée pour naviguer dans des systèmes vasculaires, et comprend en outre au moins deux ballonnets à chambres engagés de façon étanche sur l'arbre de cathéter, le premier ballonnet étant positionné à proximité de l'embout distal de l'arbre de cathéter, et l'au moins second ballonnet étant positionné adjacent au premier ballonnet. Au moins deux marqueurs de référence sont placés sur l'arbre de cathéter sous-jacent à au moins l'un des ballonnets.
