Abstract

An implantable heart help device adapted for implantation in a human patient is provided. The device comprising a fixating member adapted to fixate said device to a part of the human body comprising bone. Further a method of fixating an implantable heart help device in a human patient is provided. The method comprises the steps of: cutting the skin of said human patient, dissecting an area of the body comprising bone, and fixating said implantable heart help device to said part of the body comprising bone.

Claims

1. An implantable device for improving the pump function of the heart of a patient by applying an external force on the heart, said device comprising at least one heart contacting organ, periodically exerting force onto the heart muscle following the heart contractions and adding force thereto, said implantable device adapted to have a drive adapted to create kinetic movement to be used by the heart contacting organ, wherein said implantable device comprises a fixation device adapted to be mounted in a stable position to human bone allowing said drive unit and kinetic movement to get necessary contra force, wherein said'"'"'drive unit further comprising a respiration movement compensator for compensating for the respiratory movement of the heart in relation to the stable bone position.

2. The implantable device according to claim 1, wherein said respiratory movement compensator comprises a hydraulic, mechanic or pneumatic construction or a combination thereof, to compensate for the respiratory movement.

3. The implantable device according to claim 1, wherein said drive unit is adapted to be placed at least partly in the abdomen allowing the heart contacting organ to reach the heart, for creating said kinetic movement of the heart contacting organ.

4. The implantable device according to claim 1, wherein said drive unit is adapted to enter from the abdomen through the thoracic diaphragm.

5. The implantable device according to claim 1, wherein said fixation device is adapted to be mounted on the outside of the sternum, wherein said drive unit comprises an arm for passing subcutaneously from the outside of the sternum into the abdomen adapted to hold the drive unit, wherein said drive unit entering through the thoracic diaphragm holding said heart contacting organ.

6. The implantable device according to claim 1, wherein said drive unit further comprises a fibrotic tissue movement structure adapted to allow the respiratory movement of the heart in relation to the stable bone position, without interference from surrounding fibrotic tissue, when implanted in the body.

7. The implantable device according to claim 6, wherein said fibrotic tissue movement structure comprises a bellows allowing movement without stretching surrounding fibrosis, when implanted.

8. The implantable device according to claim 1, wherein said heart contacting organ can change from exerting force to a first area of the heart to exerting force to a second area of the heart, after said implantable device has been implanted in said human patient.

9. The implantable device according to claim 1, wherein said at least one heart contacting organ comprises at least one hydraulic or pneumatic cushion.

10. The implantable device according to claim 1, wherein said heart contacting organ further comprises a mechanical element, adapted to be movable to change the position of said force exerted on the heart of the human heart after said implantable device has been implanted in the human patient.

11. The implantable device according to claim 1, wherein said implantable device further comprises a plate, and wherein said at least one hydraulic or pneumatic cushion is placed in connection to said plate, and wherein said plate enables movement of said cushion in relation to said plate to change the position of said hydraulic or pneumatic cushion and thereby change the position of said force exerted on the heart of the human patient after said implantable device has been implanted in the human patient.

12. The heart assistant device according to claim 1, wherein said device is adapted to pass through a laparoscopic trocar in the patient'"'"'s body.

13. The heart assistant device according to claim 1, wherein said device is adapted to pass through an opening in the thoracic diaphragm from the abdominal side thereof.

14. The heart assistant device according to claim 1, wherein said drive unit is adapted to supply wireless or magnetic energy and said heart assistant device is adapted to receive said wireless or magnetic energy to cause movements of said heart assistant device.

15. The heart assistant device according to claim 1, wherein an energy receiver or energy source is adapted to be placed in the abdomen.

16. The heart assistant device according to claim 1, wherein said device further comprises an electric wire adapted to connect said heart assistant device or drive unit to an internal energy source, said wire adapted to pass into the right atrium of the heart and further up in the venous blood vessel system, exiting the blood vessel system in or closer to the subcutaneous area, wherein said internal energy source is adapted to be connected to said wire via the subcutaneous area.

17. The heart assistant device according to claim 1, further comprising;

i. an internal control unit,

ii. a sensor sensing physiological electrical pulses or muscle contractions of the heart, wherein

iii. said control unit controls said heart assistant device according to the sensed information.

18. The heart assistant device according to claim 1, wherein said internal energy source, comprises an internal control unit adapted to transmit energy pulses to said electrode for achieving heart muscle contractions and controlling heart contractions, wherein said control unit is adapted to coordinate the heart assistant device with the heart contractions.

19. The implantable heart help device according to claim 1, wherein said implantable device comprises a first fixating device adapted to fixate said device to a part of the human body comprising bone.

20. The implantable heart help device according to claim 1, wherein said part of the human body comprising bone is a part selected from a group consisting of:

the sternum, at least one rib and at least one vertebra.
