A device, a kit and a method is presented for permanently augmenting the pump function of the left heart. The mitral valve plane is assisted in a movement along the left ventricular long axis during each heart cycle. The very close relationship between the coronary sinus and the mitral valve is used by various embodiments of a medical device providing this assisted movement. By means of catheter technique an implant is inserted into the coronary sinus, the device is augmenting the up and down movement of the mitral valve and thereby increasing the left ventricular diastolic filling when moving upwards and the piston effect of the closed mitral valve when moving downwards.

The devices and methods described herein include a body lumen fluid flow modulator including an upstream flow accelerator and a downstream flow decelerator. The fluid flow modulator preferably includes one or more openings that define a gap/entrainment region that provides a pathway through which additional fluid from a branch lumen(s) is entrained into the fluid stream flowing from the upstream flow accelerator to the downstream flow decelerator.

The present invention relates to an apparatus (500) for supporting the heart action, preferably by displacing the heart base (110) and/or the aortic root (201), comprising at least a first anchor (501) and a pulling device or guiding device (502, 503, 732, 732a, 732b) for moving the first anchor (501), wherein the first anchor (501) is provided and designed for implantation in or on the heart base (110), the heart skeleton (120), the aortic root (201) and/or a structure in local proximity to the aortic root (210), and/or comprising at least one lifting drive (502, 503). The present invention further relates to a control device (901), an insertion system, a kit and a method for supporting the heart action.

Ventricular assist devices configured to be placed in a ventricle of a heart are described. In one embodiment, a ventricular assist device may include a pumping pouch. The pumping pouch may have an opening. The pumping pouch may be flexible, and may define an internal volume configured to fill with blood in through the opening. The ventricular assist device may also include a contraction element coupled to the contraction pouch. The contraction element may be capable of squeezing at least a portion of the pumping pouch to force at least a portion of the blood out through the opening. The ventricular assist device may also include a frame coupled to the pumping pouch. The frame may be configured to be coupled to a wall of the heart.

The invention relates to an implantable device (1) for determining a fluid volume flow (2) through a blood vessel (3), comprising: —at least one sensor (4) for recording at least one flow parameter, —a retaining means (5) for retaining a vessel wall port (6) in the region of a vessel wall (7) of the blood vessel (3), wherein the retaining means (5) is formed to retain the at least one sensor (4) in the region of the vessel wall (7).

The invention relates to a device (105) for determining a cardiac output for a cardiac assist system (100), wherein the device (105) comprises a support structure (115) and a sensor device (120). The support structure (115) comprises at least one brace (125) and a connection section (130) for connecting the device (105) to an element (110, 112) of the cardiac assist system (100). The at least one brace (125) is connected to the connection section (130) and can be folded away from the element (110, 112). The sensor device (120) is coupled to the at least one brace (125) and configured to sense a blood stream.

A cardiac support system (20) is equipped with a retaining structure (30) for the cardiac support system, said retaining structure (30) being intended to fix the cardiac support system in place. The cardiac support system comprises a device for monitoring the integrity of the retaining structure (30).
