Abstract

In a method, system and device a member is provided around an aneurysm enabling treatment and monitoring of the aneurysm. In accordance with one embodiment the device is adapted to be adjusted postoperatively. Hereby the treatment can be efficiently carried out without having to perform surgery when adjusting the member.

Claims

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

An implantable member adapted to be placed in connection with a blood vessel having an aneurysm for providing a pressure from outside the blood vessel, the device being adapted to be adjusted postoperatively.

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 the device is adapted to monitor an expansion of said aneurysm.

4. The device according to claim 1, 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 1, comprising an control unit and a sensor, wherein the control unit is adapted to control the pressure applied onto said aneurysm based on said signal generated by the sensor.

6. The device according to claim 1, wherein the surface of the member facing the blood vessel is adapted to exercise pressure on the blood vessel.

7. The device according to claim 6, wherein the pressure on the blood vessel is mechanically exercised.

8. The device according to claim 7, wherein the mechanically exercised pressure is controlled hydraulically.

9. The device according to claim 7, wherein mechanical pressure on the blood vessel is directly or indirectly exercised by a motor or a pump.

10. The device according to claim 1, wherein the implantable member is generally cylindrical

11. The device according to claim 10, wherein the implantable member comprises a number of segments being individually adjustable.

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

13. The device according to claim 12, wherein the implantable Y-shaped member is adapted to be placed at the Aorta Bifurcation.

15. The device according to claim 1, wherein the implantable member is an elastic member.

16. The device according to claim 15, wherein the elastic member is a band.

17. The device according to claim 15, wherein the elastic member is adapted to apply a pressure onto said aneurysm and has an expansion interval wherein the pressure applied is substantially constant or within an interval for treating and reducing expansion of the aneurysm.

18. The device according to claim 1, wherein the implantable member is spring loaded.

19. The device according to claim 1, wherein the implantable member is hydraulically operated.

20. The device according to claim 1, wherein the implantable member is pneumatically operated.

14. A pressure regulating system adapted to even out the difference in pressure in the implantable reservoir in the systolic and diastolic phase to reduce the differences or to achieve a substantially even pressure affecting said aneurysm from the outside of said blood vessel.
