An improved venous drainage cannula having enhanced drainage for minimally invasive surgeries involving vacuum-assisted venous drainage. The cannula includes more than two discrete segments in which suction holes are provided. There may be a distal segment with suction holes and two segments spaced proximally therefrom with suction holes. The tubular cannula body terminates in a tapered tip and the distal suction segment extends proximally therefrom. Between a first proximal suction segment and a distal suction segment, the cannula is reinforced. Likewise, the cannula is reinforced between the first proximal suction segment and the next suction segment. The reinforcement may be a helical wire molded into the wall of the cannula. The proximal suction segments are designed to reside within the right atrium during venous drainage. If one of the atrial suction segments becomes occluded by contact with the atrial wall, the other atrial suction segment maintains adequate flow from the right atrium.
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.
