A device for establishing a blood flow conduit between a chamber in a patient's heart and a remote location, the device comprising a cannula (12) having an external surface and proximal and distal end portions, where the distal end portion includes an opening that communicates with a cannula light to allow the flow of blood through it, where the distal end portion and the opening are configured for insertion into the heart chamber； and where the first and second anchor elements (80, 82) have respective maximum width dimensions extending outwardly from the outer surface of the cannula, where the first anchor element (80) is positioned more distally than the second anchoring element (82) and defines a tissue receptor space between them and where the dimension of the maximum width of the first anchoring element (80) is greater than the dimension of the maximum width of the second anchoring element (82), of so that the first anchoring element (80) is configured to be placed inside the heart chamber and the second anchoring element (82) is configured to be placed outside the heart chamber with the cardiac tissue in the tissue receiving space between stockings, characterized in that the cannula further comprises a blood flow catheter configured for introduction into the patient's venous system in order to direct the portion of the extr emo distally into the heart chamber and why the first and second anchoring elements are mobile between, firstly, the compact states during the introduction through the venous system and, secondly, the expanded states to be placed on opposite sides of heart tissue.Un dispositivo para establecer un conducto de flujo sanguíneo entre una cámara en un corazón de un paciente y una localización remota, comprendiendo el dispositivo una cánula (12) que tiene una superficie externa y porciones terminales proximal y distal, donde la porción del extremo distal incluye una abertura que se comunica con una luz de la cánula para permitir el paso del flujo
