Abstract

L'invention concerne une technique et un appareil permettant d'aspirer des substances qui obstruent partiellement ou complètement des vaisseaux sanguins ou des ventricules cardiaques. L'unité d'aspiration comprend un ensemble cathéter et un élément de succion pour aspirer les substances à travers le cathéter. L'ensemble cathéter comprend un cathéter qui circule sur un fil de guidage. Les éléments de succion modèles utilisés pour aspirer les substances occlusives comprennent une seringue ou un réservoir à vide. Le procédé de traitement du site intravasculaire consiste d'une part à faire progresser un ensemble cathéter à travers le système vasculaire du patient jusqu'à ce qu'une extrémité distale de l'ensemble cathéter atteigne une zone proche du site, et d'autre part à aspirer les substances occlusives à proximité du site à travers l'extrémité distale de l'ensemble cathéter. Le procédé comprend également des étapes additionnelles consistant à introduire une médication à travers le cathéter et à pulvériser l'occlusion ou ses éventuels résidus, avant d'aspirer les substances occlusives.
