Title (EN) CANNULA WITH ASSOCIATED FILTER AND METHODS OF USE DURING CARDIAC SURGERY
(FR) CANULE POURVUE D'UN FILTRE ET PROCEDES D'UTILISATION ASSOCIES, LORS D'UNE CARDIOCHIRURGIE
Abstract:
(EN) This invention is devices and methods for filtering blood (10). The devices generally comprise a mesh (40) for filtering blood flowing within a blood vessel, particularly within an artery such as the aorta; a structure (20) adapted to open and close the mesh within the blood vessel; and a means (72) to actuate the structure. The methods generally include the following steps: introducing a mesh (40) into a blood vessel to entrap embolic material; adjusting the mesh (40), if necessary, during the course of filtration; and removing the mesh (40) and the entrapped foreign matter from the blood vessel. Additionally, visualization techniques are used to ensure effective filtration.
(FR) L'invention concerne des dispositifs (10) et procédés de filtration du sang. Les dispositifs comprennent, d'une manière générale, un élément maillé (40) destiné à filtrer le sang circulant dans un vaisseau sanguin, notamment dans une artère telle que l'aorte, une structure (20) adaptée pour ouvrir et fermer l'élément maillé dans le vaisseau sanguin, ainsi qu'un moyen (72) de commande de la structure. Les procédés comprennent, d'une manière générale, les étapes consistant à introduire un élément maillé (40) dans un vaisseau sanguin afin de piéger toute matière embolique, le cas échéant à régler cet élément maillé (40) au cours du processus de filtration, puis à enlever ledit élément maillé (40) du vaisseau sanguin de même que les matières étrangères piégées. En outre, on utilise des techniques de visualisation afin d'assurer une filtration efficace.
