Abstract

A medical device for assisting in the maintaining of an opening created in the thoracic diaphragm is provided. The medical device comprises a diaphragm contacting part adapted to be placed in contact with the thoracic diaphragm and thereby assist in the maintaining of the opening created in the thoracic diaphragm. A pericardial drainage device for draining a fluid from the pericardium of a patient is further provided. The drainage device comprises a conduit; the conduit comprises a first and second section. At least a portion of the first section is adapted to receive a fluid inside of the pericardium. The second section of the conduit is adapted to be positioned outside of the pericardium of a patient and enable the exhaust of said fluid received from said pericardium through at least a portion of said second section.

Claims

1. A medical device for assisting in the maintaining of an opening created in the thoracic diaphragm, said medical device comprises a diaphragm contacting part adapted to be placed in contact with the thoracic diaphragm and thereby assist in the maintaining of the opening created in the thoracic diaphragm.

2. The medical device according to claim 1, wherein the diaphragm contacting part is adapted to assist in the maintaining of the opening created in the thoracic diaphragm by engaging the edges of said opening.

3. The medical device according to claim 1, wherein the diaphragm contacting part is a grommet.

4. The medical device according to claim 1 wherein the diaphragm contacting part is further adapted to be in contact with the pericardium and thereby also assisting in the maintaining of an opening in the pericardium.

5. The medical device according to claim 1, wherein the diaphragm contacting part further comprises a fixation portion adapted to assist in the fixation of said medical device to the thoracic diaphragm.

6. The medical device according to claim 5, wherein said fixation portion is adapted to enable fixation of said medical device to the thoracic diaphragm by sutures running through said fixation portion.

7. The medical device according to claim 5, wherein said fixation portion is adapted to enable fixation of said medical device to the thoracic diaphragm by staples running through said fixation portion.

8. The medical device according to claim 5, wherein said fixation portion is adapted to enable fixation of said medical device to the thoracic diaphragm by staples running in connection with said fixation portion.

9. The medical device according to claim 5, wherein said medical device further comprises a fixation member adapted to run through said fixation portion for enabling fixation of said medical device to the thoracic diaphragm, said fixation member comprises a first portion adapted to be inserted from a first side of the thoracic diaphragm, through a part of the thoracic diaphragm, and to a second side of the thoracic diaphragm, and wherein said fixation member further comprises a second portion adapted to engage the thoracic diaphragm on the second side and thereby lock said fixation member to the thoracic diaphragm.

10. The medical device according to claim 9, wherein said second portion is hinged to said first portion.

11. The medical device according to claim 1, wherein said medical device further comprises a force transferring part, and wherein said force transferring part is, adapted to travel through the opening and transfer force between the abdominal side of the thoracic diaphragm and the thoracic side of the thoracic diaphragm or the pericardium.

12. The medical device according to claim 11, wherein said force transferring part comprises a mechanical element adapted to transfer mechanical force.

13. The medical device according to claim 12, wherein said mechanical element is adapted to transfer at least one of a rotating force and a translating force.

14. The medical device according to claim 12, wherein said rotating force is an eccentrically rotating force.

15. The medical device according to claim 11, wherein said force transferring part comprises a conduit adapted to transfer hydraulic or pneumatic force.

16. The medical device according to claim 11, wherein said force transferring part comprises an electric lead adapted to transfer electric energy.

17. The medical device according to claim 11, wherein said diaphragm contacting part is adapted to at least partly encircle said force transferring part, when in use.

18. The medical device according to claim 11, wherein at least one of said diaphragm contacting part and said force transferring part comprises ceramic material.

19. The medical device according to claim 18, wherein said diaphragm contacting part and said force transferring part are adapted to contact each other in at least one contacting point, and wherein said at least one contacting point comprises said ceramic material.

20. The medical device according to claim 17, wherein said diaphragm contacting part and said force transferring part are adapted to seal against each other, such that the thorax is sealed from the abdomen in the area of the diaphragm contacting part.
