A rotor for a cardiac support system is disclosed. The rotor is assembled or can be assembled from at least four shell elements to form a hollow cylinder and/or on a shaft, wherein the shell elements are magnetized or can be magnetized alternately in magnetization direction which are oppositely directed or are orthogonal, so as to form a magnetized body having at least four magnetic poles.

A medical device for assisting a function of the heart is provided. The heart is placed in the thorax, the thoracic diaphragm is dividing the thorax from the abdomen and the pericardium is surrounding the heart and is attached to the thoracic diaphragm at a pericardial contacting section of the thoracic diaphragm. The medical device comprises a diaphragm passing part adapted to pass from the abdomen, through the thoracic diaphragm at the pericardial contacting section, into the pericardium, wherein said diaphragm passing part is adapted to allow the thoracic diaphragm to move during respiration, when implanted.

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 driving mechanism and a blood pump are disclosed. The driving mechanism comprises a housing assembly, a rotating assembly, and a sphere. The rotating assembly has a distal end and a proximal end; the distal end of the rotating assembly is rotatably mounted to the housing assembly. A first groove is formed on the proximal end of the rotating assembly, and the first groove has an internally concave first spherical wall. A second groove is formed on the housing assembly, and the second groove is arranged opposite the first groove; the second groove has an internally concave second spherical wall. A portion of the sphere is arranged within the first groove and a portion within the second groove, which are capable of sliding engagement with the first spherical wall and the second spherical wall, respectively.
