Abstract
An implantable device for improving the pump function of the heart of a human patient by applying an external force on the heart muscle. The device comprises at least one pump device comprising a heart contacting organ, an operating device for operating the heart contacting organ, and an implantable pressurized fluid system. The fluid system comprises a first implantable chamber adapted to hold a pressurized fluid, wherein said first chamber is adapted to hold a fluid having a high pressure and a second implantable chamber adapted to hold a pressurized fluid, wherein said second chamber is adapted to hold a fluid having a lower pressure. The movement of the heart contacting organ assists the pump function of the heart.
Claims19
An implantable device for improving a pump function of a heart of a human patient by applying an external force on a heart muscle of said heart, said device comprising at least one pump device adapted to assist in the pump function of the heart comprising:
- a piston adapted for reciprocating movement,
- a heart contacting organ configured to engage the heart,
- an operating device for operating the piston,
- a solid mechanical force transferring member connected to the piston and to the heart contacting organ configured to be moved by movement of the piston, to thereby move the heart contacting organ to assist the pump function of the heart, and
- a sensor and/or a measuring device and an implantable internal control unit for controlling the device in response to information being related to at least one of:
- a physical parameter of the patient sensed by the sensor or measured by the measuring device, or a functional parameter related to the device sensed by the sensor or measured by the measuring device.
