Title
(EN) CATHETER SYSTEM WITH BALLOON-OPERATED FILTER SHEATH AND FLUID FLOW MAINTENANCE
(FR) SYSTÈME DE CATHÉTER AYANT UNE GAINE DE FILTRE ACTIONNÉE PAR BALLONNET ET UN MAINTIEN D'ÉCOULEMENT DE FLUIDE
Abstract
(EN)
A catheter system includes an inflatable structural balloon and collapsible filter. The collapsible filter is deployable into an expanded configuration using the inflatable distal balloon. In the expanded configuration, one or more flow cells are formed between inflated portions of the balloon to provide continuous fluid flow between proximal and distal ends of the structural balloon. In the expanded configuration, the filter is configured to prevent particulates (e.g., dislodged thrombus, or other particulate material) from migrating beyond the filter. In the expanded configuration, the inflated structural balloon biases a perimeter of the filter toward or against a subject vessel wall.
(FR)
L'invention concerne un système de cathéter, qui comprend un ballonnet structural gonflable et un filtre pliable. Le filtre pliable peut être déployé dans une configuration étendue à l'aide du ballonnet distal gonflable. Dans la configuration étendue, une ou plusieurs cellules d'écoulement sont formées entre des parties gonflées du ballonnet pour réaliser un écoulement de fluide continu entre des extrémités proximale et distale du ballonnet structural. Dans la configuration étendue, le filtre est configuré pour empêcher des particules (par exemple, un thrombus délogé ou une autre matière particulaire) de migrer au-delà du filtre. Dans la configuration étendue, le ballonnet structural gonflé sollicite un périmètre du filtre vers une paroi de vaisseau du sujet ou contre celle-ci.
