The present invention provides a system for augmenting the contraction of a contractile organ in a subject. The system comprises at least one implantable organ contraction device comprising an electronic linear actuation device (1) for producing a contraction force; an anchoring assembly (13,14) for operably coupling the electronic linear actuation device to at least one wall of the contractile organ; and a controller (65) configured to modify the output parameters of the electronic linear actuation device so as to activate the electronic linear actuation device in a pattern synergistic to the natural contraction cycle of the contractile organ.

The present invention concerns a device for the ventricular emergency support, comprising: a first flexible catheter (2), with a variable transversal section, provided with an extremal balloon (7) for the controlled occlusion of the ascending aorta (AA) of the treated patient; a first pump (12), associated to said first catheter (2) for the aspiration and contemporary input of equivalent blood quantifies into the blood circle of the treated patient; a second flexible catheter (32), with a fixed transversal section, provided with a couple of extremal balloons (34), spaced apart, for the controlled occlusion of the inferior vena cava (CA) and of the superior vena cava (CD) of the treated patient; a second pump (35), associated to said first and second catheter (2, 32) for inflating and deflating said extremal balloons (7, 34) of said first and second catheter (2, 32); an electronic control unit (36) for adjusting and controlling the operational parameters of said first and second pump (12, 35), and for the detection of the cardiac parameters of the treated patient; rechargeable or network means (37, 38) for the power supply of above mentioned components.

A system configured to be at least partially implanted along an aorta includes an inelastic, static member and a pinching member. The pinching member is configured to receive an activation signal at an activation rate and in response to the activation signal, repeatedly compress the aorta at the second location at the activation rate to pump fluid within the aorta in a desired pumping direction. The system is configured to selectively control wave reflections in order to achieve both improved wave dynamics to reduce cardiac load and increased (or at least non-diminished) blood flow to targeted organs within the cardiovascular system.

A blood pump comprises a pump casing having a blood flow inlet and a blood flow outlet, and an impeller arranged in said pump casing so as to be rotatable about an axis of rotation. The impeller has blades sized and shaped for conveying blood from the blood flow inlet to the blood flow outlet. The blood pump also has an outflow cannula having an upstream end portion, a downstream end portion and an intermediate portion extending between the upstream end portion and the downstream end portion. The upstream end portion of the outflow cannula is connected to the pump casing such that blood is conveyed from the blood flow outlet of the pump casing into and through the intermediate portion of the outflow cannula towards the downstream end portion of the outflow cannula, wherein the downstream end portion has a blood flow outlet through which blood can exit the outflow cannula. At least a portion of the intermediate portion of the outflow cannula has an outer diameter that is larger than an outer diameter of the pump casing.
