Title (EN) ARTERIAL CANNULA WHICH ALLOWS PROXIMAL AND DISTAL PERFUSION WITHIN A CANNULATED VESSEL
(FR) CANULE ARTÉRIELLE QUI PERMET UNE PERFUSION PROXIMALE ET DISTALE À L'INTÉRIEUR D'UN VAISSEAU CANULÉ
Abstract: front page image
(EN)A cannula includes a first segment configured to reside entirely within a vessel. The first segment includes a proximal exit opening disposed nearer to the heart, and multiple fenestrations disposed distally away from the proximal exit opening near a cannulation site. The fenestrations in combination with the proximal exit opening enable simultaneous perfusion of blood into the cannulated vessel along proximal and distal directions. During a medical procedure, blood introduced into a vessel (e.g., the femoral artery) by way of the cannula can exit the cannula in a manner that provides concurrent blood flow in a first set of directions proximally towards the heart and a second set of directions distally away from the heart. Radially displaceable anchoring elements positionable adjacent to the vessel's superficial wall aid retention of the first segment in the vessel. The fenestrations and/or anchoring elements can be arranged obliquely around portions of the cannula's circumference.
(FR)L'invention concerne une canule qui comprend un premier segment conçu pour être entièrement situé à l'intérieur d'un vaisseau. Le premier segment comprend une ouverture de sortie proximale placée plus près du coeur, et de multiples perforations placées en position distale à l'opposé de l'ouverture de sortie proximale à proximité d'un site de canulation. Les perforations en combinaison avec l'ouverture de sortie proximale permettent la perfusion simultanée de sang dans le vaisseau canulé dans les directions proximale et distale. Pendant une intervention médicale, du sang introduit dans un vaisseau (par exemple, l'artère fémorale) au moyen de la canule peut sortir de la canule de manière à former un flux de sang simultané dans un premier ensemble de directions proximales vers le cœur et un second ensemble de directions distales à l'opposé du cœur. Des éléments d'ancrage mobiles en direction radiale qui peuvent être placés en position adjacente à la paroi superficielle du vaisseau facilitent le maintien du premier segment dans le vaisseau. Les perforations et/ou les éléments d'ancrage peuvent être agencés en oblique autour de parties de circonférence de la canule.
