A medical device including an artificial contractile structure which may be advantageously used to assist the functioning of a hollow organ. Specifically, the medical device includes an artificial contractile structure with at least one contractile element adapted to contract an organ, in such way that the contractile element is in a resting or in an activated position, at least one actuator designed to activate the contractile structure, and at least one source of energy for powering the actuator. The medical device also includes a means for reducing corrosion of the medical device hence reducing the risk of the device dysfunction and patient contamination.

A blood pump comprises a pump casing having a blood flow inlet and outlet, and an impeller arranged in said pump casing so as to be rotatable. The impeller has blades sized and shaped for conveying blood from the blood flow inlet to the blood flow outlet. The blood pump comprises an outflow cannula having an upstream end portion, a downstream end portion and an intermediate portion. The upstream end portion is connected to the pump casing such that blood is conveyed from the blood flow outlet through the intermediate portion towards the downstream end portion. 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.

An implantable medical device includes a functional unit, an introducer unit for introducing and/or navigating the functional unit in a lumen of body conduit(s) of a subject, and an elongated operable element connectable to a controller for operating the functional unit though the elongated operable element in a lumen of body conduit(s) of the subject. The functional unit, introducer unit, and elongated operable element may be in a slidable relationship for assembling and unassembling the implantable medical device in vivo. The implantable medical device is implantable, explantable, and operable in a lumen of body conduit(s) of a subject according to related methods.

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.

The invention relates to a system for ventricular circulatory support, comprising a device (2) for applying a magnetic field to a magnetised body fluid (1), particularly blood, in a region of a vessel (3), particularly a blood vessel. The system also comprises a control device designed to actuate said device (2) for applying a magnetic field such that, in the region of the vessel (3), a magnetically-induced force acts on the magnetised body fluid (1) in the longitudinal direction of said vessel (3).
