Device and a method for augmenting heart function
First Claim
1. A medical device adapted to enhance intra-cardiac blood circulation of a heart of a patient by assisting left ventricular pump action, said device having a displacement means for controllably assisting movement of a mitral valve in a mitral valve plane substantially along a long axis of a left ventricle of said heart, and said displacement means configured to be arranged in said heart of said patient in contact with said mitral valve to push and/or pull said mitral valve such that said mitral valve moves in a reciprocating movement that is assisted during systole along said long axis towards an apex of said heart and/or during diastole along said long axis away from said apex for assisting said pump action of said heart.

Abstract
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 the heart in systole and/or away from the apex in diastole.

28. A medical method of delivering a medical device adapted to enhance intra-cardiac blood circulation of a heart of a patient by assisting left ventricular pump action, said medical device having a displacement means for controllably moving a mitral valve in a mitral valve plane substantially along a long axis of a left ventricle of said heart, and said displacement means being configured to be arranged in said heart of said patient in contact with said mitral valve to push and/or pull said mitral valve such that said mitral valve is moved in a reciprocating movement that is assisted during systole towards an apex of said heart and/or during diastole away from said apex for assisting said pump action of said heart, said method comprising
providing a medical system including said medical device and an energy source, and surgically and/or minimally invasively delivering said medical system in said patient.

40. A system for permanently enhancing left ventricular pump function of a heart of a patient, said system comprising a displacement means for controllably assisting mitral valve movement synchronized with a cardiac cycle of said heart substantially along a long axis of a left ventricle of said heart, said displacement means being configured to be arranged in said heart of said patient in contact with said mitral valve to push and/or pull said mitral valve such that said mitral valve moves in a reciprocating movement that is assisted during systole towards an apex of said heart and/or during diastole away from said apex for assisting pump action of said heart.
