Abstract

La présente invention concerne un dispositif de protection contre l'embolie utilisé dans un vaisseau sanguin lors d'une intervention dans une région sténosée ou occluse afin de capturer toute matière embolique qui pourrait être créée et relâchée dans la circulation sanguine au cours de la procédure. Le dispositif de l'invention comprend un ensemble de filtrage comportant un ensemble d'étrésillons à déploiement automatique qui est attaché à l'extrémité distale d'un fil-guide et qui se déploie à l'intérieur du système vasculaire du patient au fur et à mesure que le fil-guide est manipulé jusque dans la zone de traitement. Une gaine de retenue placée autour de l'ensemble de filtrage en un agencement coaxial maintient l'ensemble de filtrage dans une position repliée jusqu'à ce qu'il soit prêt à être déployé par le médecin. La gaine peut ensuite être rétractée de façon qu'elle expose l'ensemble de filtrage qui se déploie alors automatiquement à l'intérieur du système vasculaire du patient. Des dispositifs d'intervention peuvent être distribués au travers du fil-guide et les quelconques débris emboliques créés et relâchés dans la circulation sanguine au cours de l'intervention pénètrent dans l'ensemble de filtrage et y restent piégés. D'autres modes de réalisation comprennent des ensembles de filtrage attachés à un organe tubulaire extérieur et à un organe tige intérieur qui appliquent une force axiale sur les extrémités distales de l'ensemble pour déployer ou contracter les étrésillons selon les besoins.
