Abstract

A surgical method of implanting an implantable drainage apparatus. The method comprising the steps of cutting the skin of a patient, inserting the implantable drainage apparatus into the body of the patient, the implantable drainage apparatus comprising a drainage device, an energy source adapted to supply energy to the drainage device, a connecting tube connected to the drainage device, a bellows adapted to generate a suction and a motor connected to the bellows, being adapted to compress the bellows to move fluid out of the bellows and at the same time pre-tension the bellows, placing the drainage device at a placement area in the patient'"'"'s body, placing the connecting tube at a treatment area in the patient'"'"'s body.

Claims

1. A surgical method of implanting an implantable drainage apparatus comprising:

cutting the skin of a patient,

inserting the implantable drainage apparatus into the body of the patient, the implantable drainage apparatus comprising a drainage device, an energy source adapted to supply energy to the drainage device, a connecting tube connected to the drainage device, a bellows adapted to generate a suction and a motor connected to the bellows, the motor configured to compress the bellows to move fluid out of the bellows and at the same time pre-tension the bellows,

placing the drainage device at a placement area in the patient'"'"'s body,

placing the connecting tube at a treatment area in the patient'"'"'s body.

2. The surgical method according to claim 1, further comprising dissecting in at least one of the treatment area and the placement area.

3. The surgical method according to claim 1, wherein the surgical method is a laparoscopic method further comprising:

inserting a needle like tube into the abdomen of the patient'"'"'s body,

using the tube 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 at least one dissecting tool through a trocar and dissecting at least two areas of the patient.

4. The surgical method according to claim 1, further comprising sucking body fluid from the treatment area to the drainage device, through the connecting tube.

5. The surgical method according to claim 1, wherein the implantable drainage apparatus further comprises a second tube connected to the drainage apparatus, and wherein the surgical method further comprises placing the second tube at a delivery area of the patient.

6. The surgical method according to claim 5, further comprising delivering body fluid from the drainage device to the delivery area, through second tube.

7. The surgical method according to claim 5, wherein placing the second tube at a delivery area of the patient comprises placing the second tube such that it leads to the urine bladder.

8. The surgical method according to claim 5, wherein placing the second tube at a delivery area of the patient comprises placing the second tube such that it leads to the abdomen.

9. The surgical method according to claim 1, wherein placing the drainage device at a placement area in the patient'"'"'s body comprises placing the drainage device in the abdomen of the patient.

10. The surgical method according to claim 1, wherein placing the connecting tube at a treatment area in the patient'"'"'s body comprises placing the connecting tube at the renal part of the kidney area.

11. The surgical method according to claim 1, wherein placing the connecting tube at a treatment area in the patient'"'"'s body comprises placing the connecting tube at an area of the brain.

12. The surgical method according to claim 1, wherein placing the connecting tube at a treatment area in the patient'"'"'s body comprises placing the connecting tube at an area of the lymphatic system.

13. The surgical method according to claim 1, wherein placing the connecting tube at a treatment area in the patient'"'"'s body comprises placing the connecting tube at an area of the thorax.

14. The surgical method according to claim 1, wherein placing the connecting tube at a treatment area in the patient'"'"'s body comprises placing the connecting tube at an area of the abdomen.

15. The surgical method according to claim 1, further comprising implanting a sensor connected to the drainage apparatus, the sensor being adapted to sense at least one of a physical parameter of the patient and a functional parameter of the drainage apparatus.

16. The surgical method according to claim 15, wherein implanting a sensor comprises implanting a pressure sensor.

17. The surgical method according to claim 1, further comprising supplying energy to the drainage device from the energy source.

18. The surgical method according to claim 1, further comprising operating the motor for pre-tensioning the bellows.

19. The surgical method according to claim 1, wherein inserting the implantable drainage apparatus into the body of the patient comprises implanting an implantable drainage apparatus comprising an energy transforming device.

20. The surgical method according to claim 1, wherein inserting the implantable drainage apparatus into the body of the patient comprises implanting an implantable drainage apparatus comprising a bellows comprising a spring adapted to pre-tension the bellows.
