Abstract

In a system, device and method for treating an aneurysm of a human or mammal patient an implantable member adapted to hold fluid is provided. The member is adapted to be placed in connection with a blood vessel having the aneurysm and to exercise a pressure on the aneurysm of said blood vessel.

Claims

1. A device for treating an aneurysm of a human or mammal patient comprising:

An implantable member adapted to hold fluid, wherein said member is adapted to be placed in connection with a blood vessel having the aneurysm, the member being adapted to exercise a pressure on the aneurysm of said blood vessel.

2. The device according to claim 1, wherein the device is adapted to prevent or reduce an expansion of said aneurysm.

3. The device according to claim 1, wherein said device is adapted to be postoperatively adjusted.

4. The device according to claim 3, wherein the device is adapted to perform self adjustments of the pressure applied onto said aneurysm within a predetermined treatment interval.

5. The device according to claim 4, further comprising a control unit and a sensor, the control unit being adapted to control pressure adjustments of based on a signal generated by the sensor.

6. The device according to claim 1, further comprising a pressure regulator adapted to regulate the pressure in the member.

7. The device according to claim 6, wherein the pressure regulator is adapted to even out the difference in pressure in the implantable member during the systolic and diastolic phase for reducing the pressure difference or providing a substantially even outside pressure on the aneurysm.

8. The device according to claim 6, wherein the pressure regulator comprises pressure tank.

9. The device according to claim 1, wherein the implantable member is Y-shaped.

10. The device according to claim 9, wherein the implantable Y-shaped member is adapted to be placed at the Aorta Bifurcation

11. The device according to claim 6, wherein the pressure regulator comprises an expandable first reservoir.

12. The device according to claim 11, wherein the expandable first reservoir is spring loaded.

13. The device according to claim 6, wherein the pressure regulator comprises a pump.

14. The device according to claim 11, further comprising a second reservoir and a pump adapted to move liquid between the first and second reservoirs.

15. The device according to claim 14, wherein said first reservoir has a predetermined optimal pressure regulation volume treatment interval and wherein said pump is adapted to pump liquid from the first to the second reservoir to keep said first reservoir within said regulation interval, when said aneurysm expands and to pump liquid from said implantable member into said first reservoir.

16. The device according to claim 1, wherein the provided pressure is equal or less than the diastolic blood pressure of a treated patient.

17. The device according to claim 1, wherein the device is adapted to increase the pressure on the blood vessel when the aneurysm expands.

18. The device according to claim 17, comprising a control device adapted to increase the pressure on the blood vessel when the aneurysm expands more than a predetermined value.

19. The device according to claim 18, comprising a control device adapted to increase the pressure on the blood vessel when the aneurysm expands more than a predetermined value during a time period.

20. The device according to claim 17, further comprising a control unit adapted to control the expansion of said aneurysm by controlling the pressure applied on the blood vessel when the aneurysm expands.
