A device, a kit and a method are presented for permanently augmenting the pump function of the left heart. The basis for the presented innovation is an augmentation of the physiologically up and down movement of the mitral valve during each heart cycle. By means of catheter technique, minimal surgery, or open heart surgery implants are inserted into the left ventricle, the mitral valve annulus, the left atrium and adjacent tissue in order to augment the natural up and down movement of the mitral valve and thereby increasing the left ventricular diastolic filling and the piston effect of the closed mitral valve when moving towards the apex of said heart in systole and/or away from said apex in diastole.

The devices and method described herein allow for therapeutic damage to increase volume in these hyperdynamic hearts to allow improved physiology and ventricular filling and to reduce diastolic filling pressure by making the ventricle less stiff. For example, improving a diastolic heart function in a heart by creating at least one incision in cardiac muscle forming an interior heart wall of the interior chamber where the at least one incision extends into one or more layers of the interior heart wall without puncturing through the interior heart wall and the incision is sufficient to reduce a stiffness of the interior chamber to increase volume of the chamber and reduce diastolic filing pressure.

A medical device delivery system can comprise a delivery catheter and an in-line sheath, the delivery catheter being preloaded within the in-line sheath. The delivery catheter can comprise a catheter hub and a catheter shaft. The catheter shaft can comprise a proximal portion extending distally from the hub and slidably receiving a proximal narrow portion of a medical device, and a distal portion slidably receiving a distal wide portion of a medical device. The in-line sheath can comprise a sheath hub and a sheath shaft. The sheath shaft can comprise a proximal portion extending distally from the sheath hub and slidably receiving at least a portion of the proximal portion of the catheter shaft, and an expandable distal portion slidably receiving the distal portion of the catheter shaft.

A medical device for causing blood flow within a left atrial appendage (LAA) includes a flow energy capture element adapted to capture energy caused by movement within the heart. A transmission element is operably coupled to the flow energy capture element, the transmission element adapted to utilize the captured energy to cause blood flow within the LAA.

A cardiac assist system using a helical arrangement of contractile bands and a helically-twisting cardiac assist device are disclosed. One embodiment discloses a cardiac assist system comprising at least one contractile elastic band helically arrangement around a periphery of a patient's heart, where upon an actuation the band contracts helically, thereby squeezing the heart and assisting the pumping function of the heart. Another embodiment discloses a helically twisting cardiac-apex assist device comprising an open, inverted, substantially conical chamber with two rotatable ring portions of different diameters located at the base and apex of the chamber, with a plurality of substantially helical connecting elements positioned substantially flush with the chamber wall and connecting the two rotatable ring portions, whereby a relative twisting motion of the two rings causes a change in volume of the chamber thereby assisting the cardiac pumping function.

Methods and apparatuses relate to an implantable device for providing contractile assistance to an organ. The device may include an actuator and anchors located on either side of the actuator. The anchors engage with oppositely positioned tissue walls of an organ chamber, and provide contractile assistance to the organ, repeatedly, at appropriate times. For example, the device may be implanted within the right ventricle, anchored to the right ventricular free wall and the ventricular septum. The device may function to bring the opposing walls of the ventricle toward one another, synchronized with the pacing of the heart, resulting in an improved ejection fraction of blood from the chamber. In some embodiments, the actuator includes a bladder that is configured to contract upon receiving an inflow of pressurized fluid therein. When the fluid exits therefrom, the bladder relaxes back to an initial, extended state.

The present invention provides methods and systems for a biomaterial medical implant device for treating patients with HF and/or intractable dyrhythmia. It either is implanted inside the cardiac cavity(ies), ICI, or after their removal, TAH. The embodiment consists of 2 layers. Layer 1 (16) is immobile and adherent to the basement. Layer 2 (17) reflects from layer 1 and faces the cavity. Layer 2 moves inwards (systole) and backwards (diastole) by between-layers Concertina-like elastic fibers and/or a spring (22), on-surface diagonally crossing elastic fibers (27), or sheets (29&30) of electromagnetic coils (34), that are adherent to both layers from the inside. Layer 2 moves through the electromagnetic coil causing its attraction to layer 1, when polarities are different and repulsion when polarities are similar.
