Patent

CA 2663207

There is disclosed a porous emboli deflector for preventing cerebral emboli while maintaining cerebral blood flow during an endovascular or open surgical procedure. The device prevents the entrance of emboli of a size able to cause stroke from entering either the right or left carotid arteries by deflecting emboli downstream in the blood flow. The device can be placed prior to any manipulation of the heart or aorta allowing maximal protection of the brain during the index procedure. The device has a low profile within the aorta which allows sheaths, catheters, or wires used in the index procedure to pass. Also disclosed are methods for insertion and removal of the device.

L'invention porte sur un déflecteur poreux d'emboles empêchant les embolies cérébrales tout en maintenant la circulation sanguine lors d'une intervention chirurgicale endovasculaire ou ouverte. Le dispositif empêche l'entrée d'emboles d'une taille pouvant provoquer une attaque dans la carotide droite ou gauche en défléchissant les emboles vers l'aval de la circulation sanguine. Le dispositif, qui se pose avant toute manipulation du coeur ou de l'aorte, assure une protection maximale du cerveau pendant la procédure de repérage. Le dispositif présente un profil bas dans l'aorte ce qui laisse passer les gaines les cathéters ou fils utilisés dans une telle procédure. L'invention porte également sur des procédés de pose et de retrait du dispositif.
