Title
(EN) DISTAL PROTECTION AND DELIVERY SYSTEM AND METHOD
(FR) PROCEDE ET SYSTEME DE PROTECTION DISTALE ET D'APPORT
Abstract
(EN)
A distal protection and delivery system is used to collect and remove embolic debris in the blood vessel. The system includes a guidewire (5), a filter assembly (10) and a distal introducer (15). The distal introducer (15) can be positioned on a distal end of an introducer catheter or an angioplasty catheter or other interventional catheter. The guidewire (5) has a small ferrule (30) or locking mechanism fixed to it which does not affect the flexibility, torqueability, or trackability in comparison to standard guidwires. The introducer containing the filter assembly (10) is advanced over the guidewire (5) to a site distal to the lesion. Upon retraction of the guidewire (5) proximally, the ferrule (30) latches with an ejector latch (60) of the filter assembly (10). Either advancement of the guidewire (5) distally or retraction of the distal introducer (15) proximally allows the filter assembly (10) to be ejected from the distal introducer (15) and into the blood vessel.

La présente invention concerne un système de protection distale et d'apport utilisé afin de recueillir et évacuer les débris emboliques dans le vaisseau sanguin. Ce système comprend un fil-guide (5), un ensemble filtre (10) et un introducteur distal (15). L'introducteur distal (15) peut être positionné sur une extrémité distale d'un cathéter d'introduction ou d'un cathéter d'angioplastie ou autre cathéter interventionnel. Le fil-guide (5) présente une petite virole (30) ou mécanisme de blocage fixé sur ce dernier qui n'affecte pas la flexibilité, l'aptitude à la torsion, ou l'aptitude au guidage par rapport aux fils-guides classiques. L'introducteur contenant l'ensemble filtre (10) est avancé sur le fil-guide (5) jusqu'à un site distal par rapport à la lésion. Lors de la rétraction du fil-guide (5) de manière proximale, la virole (30) se verrouille avec un verrou d'éjection (60) de l'ensemble filtre (10). L'avancement du fil-guide (5) de manière distale ou la rétraction de l'introducteur distal (15) de manière proximale permet d'éjecter l'ensemble filtre (10) de l'introducteur distal (15) dans le vaisseau sanguin.
