Left Heart Assist Device and Method
20210052386 · 2021-02-25 · ·

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.

An implantable ventricular assist device comprises an intraventricular stent used for the creation of an artificial chamber inside the ventricle, a balloon-like structure used to drive the change of the artificial chamber between a contractile configuration and a diastolic configuration, a power system used for driving the change of the balloon-like structure between the contractile configuration and the diastolic configuration. There is also a power system and a mechanical design to operate the system working, wherein in the contractile configuration, the balloon-like structure expands and occupies the space of the artificial chamber and drives the blood inside the artificial chamber flow outside the artificial chamber, wherein in the diastolic configuration, the balloon-like structure shrinks and releases the space inside the artificial chamber, and the blood outside the artificial chamber flows back into the artificial chamber. It is easy to reach the goal of cardiac function.

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.

MECHANICAL ASSIST DEVICE

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.
