Abstract
La présente invention concerne une canule de retour veineux à drainage renforcé ne nécessitant qu'une chirurgie invasive minimale mettant en oeuvre un drainage veineux assisté par aspiration. Cette canule comprend plus de deux segments distincts pourvus de trous d'aspiration. Il peut y avoir un segment distal pourvu de trous d'aspiration et deux segments placés à proximité du premier pourvus de trous d'aspiration. Le corps tubulaire de cette canule se termine en une pointe effilée et le segment d'aspiration distal est situé à proximité de celle-ci. La canule est renforcée entre un premier segment d'aspiration proximal et un segment d'aspiration distal. Cette canule est renforcée de la même manière entre le premier segment d'aspiration proximal et le segment d'aspiration suivant. Ce renfort peut consister en un câble hélicoïdal moulé dans la paroi de la canule. Les segments d'aspiration proximaux sont conçus pour loger dans l'oreillette droite pendant le drainage veineux. Si l'un des segments d'aspiration atriaux se bouche au contact de la paroi atriale, l'autre segment d'aspiration atrial maintient un débit approprié en provenance de l'oreillette droite.
