1. A medical device for enhancing intracardiac blood circulation in a patient’s heart by supporting the pumping action of the left ventricle, said device comprising: a movement unit configured to provide controlled support for moving the mitral valve plane along the long axis of the left ventricle of the heart and configured to be located in the heart patient and being in contact with said mitral valve to push and / or pull the mitral valve in such a way that -sectoral valve is moved to move the block by means of a reciprocating movement during systole along said long axis to the apex of the heart or during diastole along said long axis of said top for supporting serdtsa.2 pumping action. The device of claim 1, wherein the displacement unit comprises a mechanical unit configured to apply a mechanical support force to the mitral valve for at least a portion of the systole to enhance the natural pressure force of the heart, or for at least a portion diastoles to increase the natural filling of the left ventricle. 3. The device according to claim 2, in which the mechanical unit has a proximal end portion that is attached to the location of the mitral valve, for example, a mitral valve ring, and a distal end portion that is attached to the energy conversion unit (58), which converts energy from a remote source ( 84) energy into a linear force and / or rotational force to provide said supporting force1. Медицинское устройство для усиления внутрисердечной циркуляции крови в сердце пациента посредством поддержки насосного действия левого желудочка, при этом упомянутое устройство содержит:блок перемещения, выполненный с возможностью управляемой поддержки перемещения плоскости митрального клапана вдоль длинной оси левого желудочка сердца и сконфигурированный с возможностью расположения в сердце пациента и нахождения в контакте с упомянутым митральным клапаном, чтобы толкать и/или оттягивать митральный клапан таким образом, что митральный клапан двигается в блоке перемещения
