Abstract

In accordance with the present invention, there is provided a system for treating a patient with local hypertension, comprising a hypertension treatment device adapted to have at least one surface of the device attached to the blood flow passageway, wherein said surface comprising a cooling surface able to cool said passageway to restrict said passageway thereby reducing the blood pressure distal to said restriction. In accordance with a another aspect of the present invention, there is provided a system for treating a patient with aneurysm, comprising a aneurysm treatment device adapted to have at least one surface of the device attached to the blood flow passageway, wherein said surface comprising a cooling surface able to cool said passageway to restrict said passageway thereby treating said aneurysm. In accordance with a second aspect of the present invention, there is provided a system for treating a patient with hypotension, comprising a hypotension treatment device adapted to have at least one surface of the device attached to the blood flow passageway, wherein said surface comprising a heating surface able to heat said passageway to dilate said passageway thereby increasing the blood pressure distal to said restriction.

Claims

1. A system for treating a patient with hypertension, comprising a hypertension treatment device adapted to have at least one surface of the device attached to the blood flow passageway, wherein said surface comprising a cooling surface able to cool said passageway to restrict said passageway thereby reducing the blood pressure distal to said restricted blood flow passageway.

2. The system according to claim 1, comprising a control device for controlling the temperature of said cooling surface.

3. The system according to claim 1, comprising a mechanical or hydraulic constriction device for co-operating with said cooling surface to cause said restriction.

4. The system according to claim 2, wherein said control device comprising an internal control unit, wherein the temperature of said cooling surface is controlled by the internal control unit.

5. The system according to claim 2, comprising a sensor sensing a physical parameter of the patient or a functional parameter of the device, wherein the internal control unit controls said cooling surface in response to said sensor.

6. The system according to claim 5, wherein said sensor is sensing the blood pressure.

7. The system according to claim 1, wherein said hypertension treatment device is adapted to be placed on the pulmonary artery to reduce high blood pressure in the pulmonary region.

8. The system according to claim 2, comprising a power supply and an electronic circuitry adapted to power the cooling surface.

9. The system according to claim 8, wherein said power supply is a rechargeable power supply.

10. The system according to claim 8, wherein the cooling surface comprising an electronic element further creating heat on a second surface.

11. The system according to claim 10, wherein the electronic element is a peltier element.

12. The system according to claim 10, comprising a water cooling system adapted to transport away heat from the second surface.

13. The system according to claim 9, comprising a wireless energy transmitter for wireless charging of the power supply from outside the patients body.

17. The method according to claim 12, wherein the blood vessel is a blood vessel leading from the right heart chamber to the lung of the patient, wherein the hypertension treatment device is treating a high blood pressure in this pulmonary vascular system.

14. A method for controlling hypertension in a human or mammal vascular system, the method comprising the steps of:

inserting a needle like tube into the abdomen of the patients body,

using the tube like needle like to fill the abdomen with gas thereby expanding the abdominal cavity,

placing at least two laparoscopic trocars in the patient'"'"'s body,

inserting a camera through one of the trocars into the abdomen,

inserting a dissecting tool through any of the trocar and dissecting an area of at least one portion of a blood vessel of the patient,

placing a hypertension treatment device comprising a cooling surface, attached in relation to the blood vessel, and

cooling a wall portion of the blood vessel to cause contraction of the wall portion to create a constriction of the blood vessel, to further influence a blood pressure difference before and after the constriction of the blood vessel.

15. The method according to claim 14, wherein the blood vessel is a arterial blood vessel leading from the abdominal aorta to an organ of the patient, wherein the hypertension treatment device is treating a high blood pressure in this vascular system.

16. A method for controlling hypertension locally in a human or mammal patients vascular system, the method comprising the steps of:

inserting a needle like a tube into the thorax of the patients body,

using the tube like needle to fill the thorax with gas thereby expanding the thoracal cavity,

placing at least two laparoscopic trocars in the patient'"'"'s body,

inserting a camera through one of the trocars into the thorax,

inserting a dissecting tool through any of the trocar and dissecting an area of at least one portion of a blood vessel,

placing a hypertension treatment device comprising a cooling surface attached in relation to the blood vessel and

cooling a wall portion of the blood vessel to cause contraction of the wall portion to create a constriction of the blood vessel, to further influence a blood

pressure difference before and after the constriction of the blood vessel.

18. A method for controlling hypertension locally in a human or mammal patients vascular system, the method comprising the steps of:

cutting the patients skin,

dissecting the area of a blood vessel,

placing a hypertension treatment device comprising a cooling surface attached in relation to the blood vessel and

cooling a wall portion of the blood vessel to cause contraction of the wall portion to create a constriction of the blood vessel, to create a blood pressure

difference before and after the constriction of the blood vessel.

19. A system for treating a patient with hypotension, comprising a hypotension treatment device adapted to have at least one surface of the device attached to the blood flow passageway, wherein said surface comprising a heating surface able to heat said passageway to dilate said passageway thereby increasing the blood pressure distal to said dilated blood flow passageway.

20. The system according to claim 19, comprising a control device for controlling the temperature of said heating surface.
