The present invention relates to a medical chamber system (700) for implantation in the chest of a patient to support the heart activity, preferably by displacing the heart apex (105), comprising at least a first chamber (702) for arrangement inside the heart sac (300) and a second chamber (701) for arrangement outside the heart sac (300), wherein the chambers (701, 702) comprise at least one connection portion or connection channel (703) which connects the two chambers (701, 702) to each other, the chambers (701, 702) and the connection channel (703) are further embodied to be filled with fluid (705) and, preferably in the implanted state, to be arranged such that the heart activity acts on the first chamber (702) and that the second chamber (701) acts as a volume storage and/or energy storage for the fluid (705). Furthermore, the present invention relates to an introduction system for a medical chamber system (700) and to a kit, encompassing a medical chamber system (700) and an introduction system.

A pericardial anchor for positioning a cardiac assist system over a patient's heart beneath the patient's sternum and ribs includes a tubular shaft, a pericardial anchor, and a removable handle. The tubular shaft has a guidewire lumen therethrough. The pericardial anchor is positioned at a distal end of the tubular shaft, and the removable handle is positioned at a proximal end of the tubular shaft. The pericardial anchor is typically a helical anchor that can be implanted to anchor in the patient's pericardium by rotation of the handle. The tubular shaft receives and anchors a cardiac assist system over the patient's heart beneath the patient's sternum and ribs after the handle is removed.

A cardiac assist device includes an expandable cup with a pumping chamber having at least one inflow aperture, an outflow nozzle in communication with the chamber, and a volume displacement member inside the chamber. The volume displacement member is cyclically movable between a low-volume state and a high-volume state at a frequency F, wherein a displacement volume of blood Vd is displaced from the chamber through the nozzle during each cycle. When the volume displacement member moves at frequency F, the device increases momentum of blood flowing through the device such that flow rate of blood exiting the nozzle is substantially greater than the frequency F multiplied by the displacement volume Vd. In some embodiments, the volume displacement member includes a balloon having a proximal region that is distanced from an inner wall of the chamber more than a distal region of the balloon when the balloon is fully inflated.
