Abstract

The present invention relates to a method of implanting a blood clot removal device in a patient's body, by cutting the skin of the patient's body, dissecting an area of the patient's vascular system, placing the blot clot removal device at the dissected area, and connecting a blood flow passageway of the blood clot removal device to the patient's vascular system to allow circulation of the patient's blood through the blood flow passageway.

First claim

The invention claimed is:

1. A method of implanting a blood clot removal device in a patient's body, the method comprising:
cutting the skin of the patient's body,
dissecting an area of the patient's vascular system,
placing the blot clot removal device at the dissected area, the blood clot removal device comprises a blood flow passageway having a first side wall and a second side wall, a filter provided in the blood flow passageway for filtering blood clots, a cleaning device for cleaning the filter configured to remove blood clots from the filter by moving blood clots along the filter from the first side wall toward the second side wall to move blood clots away from the blood flow passageway;
connecting the blood flow passageway of the blood clot removal device to the patient's vascular system to allow circulation of the patient's blood through the blood flow passageway.

2. The method according to claim 1 , wherein the method is a surgical abdominal approach, and wherein the step of cutting the skin of the human patient comprises cutting the skin at the abdominal region of the patient.

3. The method according to claim 2 , further comprising the step of placing a blood clot removal device at the dissected area comprises placing a blood clot removal device in any part of the vascular system in the abdomen.

4. The method according to claim 2 , wherein the method is a laparoscopic abdominal approach.

5. The method according to claim 4 , further comprising at least one of the steps of:
inserting a needle or a tube-like instrument into the abdomen of the patient's body,
using the needle or a tube-like instrument to fill the patient's abdomen with gas thereby

expanding the patient's abdominal cavity, and
placing the blood clot removal device in any part of the vascular system in the abdomen.

6. The method according to claim 1 , wherein the method is a surgical thoraxical approach, and wherein the step of cutting the skin of the human patient comprises cutting the skin at the thoraxical region of the patient.

7. The method according to claim 6 , further comprising placing a blood clot removal device in any part of the vascular system in the thorax.

8. The method according to claim 6 , wherein the method is a laparoscopic thoraxical approach.

9. The method according to claim 8 , further comprising at least one of the steps of:
inserting a needle or a tube like instrument into the thoraxical region of the patient's body,
using the needle or a tube like instrument to fill the patient's thoraxical region with gas thereby expanding the patient's thoraxical cavity, and
placing the blood clot removal device in any part of the vascular system in the thoraxical region.

10. The method according to claim 1 , further comprising the step of placing a source of energy in the patient's body for powering the blood clot removal device.

11. The method according to claim 10 , further comprising the step of wirelessly charging the source of energy, after said source of energy has been implanted in the patient's body.

12. The method according to claim 1 , further comprising the step of programming the blood clot removal device from outside the body of the patient.

13. The method according to claim 1 , further comprising the step of non-invasively regulating at least one function of the blood clot removal device from outside the patient's body.

14. The method according to claim 1 , further comprising the step of wirelessly communicating with the blood clot removal device, non-invasively from outside of the body of the patient.

15. The method according to claim 14 , wherein the step of wirelessly communicating with the blood clot removal device comprises sending feedback information from inside the patient's body to the outside thereof, said feedback information being related to a functional parameter of the blood clot removal device or a physical parameter of the patient.

16. The method according to claim 15 , wherein the functional parameter of the blood clot removal device is correlated to the transfer of energy for charging an internal energy source.

17. The method according to claim 1 , further comprising the step of transforming wireless energy into electrical energy inside the patient's body using an implanted energy-transforming device.

18. The method according to claim 1 , further comprising the step of moving blood clots away from the vascular system by means of the blood clot removal device.

19. The method according to claim 1 , wherein the mechanical cleaning device is movable in a direction perpendicular to the direction of the blood flow passageway.

20. The method according to claim 1 , wherein the cleaning device is adapted to slice, push, suck away or scratch away any clots from the filter.
