Abstract[English]
Bidirectional flow cannulas may include a main cannula tube with a central lumen that is configured to be in liquid communication with a source of blood once a portion of the bidirectional flow cannula is positioned within a patient's blood vessel. The bidirectional flow cannula may include an inflatable balloon that circumferentially surrounds a distally positioned portion of an exterior diameter the main tube that is configured to be inflated and/or deflated via an inflation line coupled to the main cannula tube. The bidirectional flow cannula may further include a first plurality of ports positioned within the main cannula tube on a proximal side of the inflatable balloon and a second plurality of ports positioned within the main cannula tube on a distal side of the inflatable balloon, and, on some occasions, the first plurality of ports including more ports than the second plurality of ports.[French]
Les canules à écoulement bidirectionnel peuvent comprendre un tube de canule principal ayant une lumière centrale qui est conçue pour être en communication liquide avec une source de sang une fois qu'une partie de la canule à écoulement bidirectionnel est positionnée à l'intérieur du vaisseau sanguin d'un patient. La canule à écoulement bidirectionnel peut comprendre un ballonnet gonflable qui entoure de manière circonférentielle une partie positionnée de manière distale d'un diamètre extérieur, le tube principal étant conçu pour être gonflé et/ou dégonflé par l'intermédiaire d'une ligne de gonflage couplée au tube de canule principal. La canule à écoulement bidirectionnel peut en outre comprendre une première pluralité d'orifices positionnés à l'intérieur du tube de canule principal sur un côté proximal du ballonnet gonflable et une seconde pluralité d'orifices positionnés à l'intérieur du tube de canule principal sur un côté distal du ballonnet gonflable et, à certaines occasions, la première pluralité d'orifices comprenant plus d'orifices que la seconde pluralité d'orifices.
