Abstract

The present application provides a subcutaneously implantable device for removing fluid from a first location in a body of a patient. The device includes a fluid controller having a fluid inlet and a fluid outlet. The fluid controller is continually operable between a first and second cycle, wherein in the first cycle the fluid controller draws fluid in through the fluid inlet and in the second cycle the fluid controller expels a first portion of the fluid out through the fluid inlet and a second portion of the fluid out through the fluid outlet.

Claims

1. An implantable device for removing fluid from a first location in a body of a patient comprising:

a first catheter including a first end positionable within the first location in the body of the patient and a second end;

a second catheter including a first end and a second end;

a reservoir in fluid communication with the second end of the first catheter and the first end of the second catheter;

a one way valve interposed between the reservoir and the first end of the second catheter; and

a pump connected to the reservoir and operable between a first and second cycle, wherein in the first cycle the fluid is drawn in through the first catheter into the reservoir and in the second cycle a first portion of the fluid is forced out of the reservoir through the first catheter into the first location and a second portion of the fluid is forced out of the reservoir through the one-way valve and the second catheter.

2. An implantable device as set forth in claim 1 further comprising a power source connected to the pump.

3. An implantable device as set forth in claim 2 wherein the power source is a battery.

4. An implantable device as set forth in claim 2 further comprising a switch interposed between the pump and the power source.

5. An implantable device as set forth in claim 4 wherein the switch comprises a manual override for operation of the pump.

6. An implantable device as set forth in claim 4 further comprising an actuation means connected to the switch.

7. An implantable device as set forth in claim 6 wherein the actuation means includes a sensor.

8. An implantable device as set forth in claim 1 further comprising a filter interposed between the reservoir and the first catheter.

9. An implantable device as set forth in claim 1 wherein the one way valve prevent fluid from entering or exiting the reservoir in the first cycle.

10. An implantable device as set forth in claim 1 wherein the second end of the second catheter is positioned in a second body portion.

11. A subcutaneously implantable device for removing fluid from a first location in a body of a patient comprising a fluid controller including a fluid inlet and a fluid outlet and having first and second operation cycles, wherein during the first operation cycle the fluid controller draws fluid in through the fluid inlet and during the second cycle the fluid controller expels a first portion of the fluid out through the fluid inlet and a second portion of the fluid out through the fluid outlet.

12. A subcutaneously implantable device as set forth in claim 11 further comprising a one-way valve connected to the fluid outlet, wherein the one way valve prevents fluid from entering or exiting the fluid controller through the fluid outlet in the first cycle.

13. A subcutaneously implantable device as set forth in claim 12 wherein the fluid controller further comprises:

a reservoir in fluid communication with the fluid inlet and the fluid outlet; and

a pump connected to the reservoir and operable between the first and second cycles.

14. A subcutaneously implantable device as set forth in claim 13 further comprising:

a power source; and

an switching means connecting the power source and the pump.

15. A subcutaneously implantable device as set forth in claim 14 wherein the switch means includes a manual override for operation of the pump.

16. A subcutaneously implantable device as set forth in claim 14 wherein the switching means comprises;

a sensor; and

a switch operably connected to the sensor.

17. A method of draining a fluid from a first location in a body of a patient comprising:

positioning a shunt system in fluid communication with the first location in the body of the patient;

draining the fluid from the first location in the body of the patient into the shunt system; and

expelling the fluid from the shunting system, wherein a first portion of the fluid is expelled from the shunt system into the first location in the body of the patient and a second portion of the fluid is expelled from the shunt system to a second location different from the first location.

18. A method as set forth in claim 17, wherein draining the fluid from the first location in the body of the patient into the shunt system comprises operating the shunt system to drawn fluid into the shunt system through a first catheter positioned in the first location in the body of the patient.

19. A method as set forth in claim 18, wherein expelling the fluid from the shunting system comprises operating the shunt system to expel the first portion of the fluid through the first catheter into the first location in the body of the patient and to expel the second portion of the fluid through a second catheter into the second location.

20. A method as set forth in claim 19, further comprising preventing fluid from entering or exiting the shunt system through the second catheter when the shunt system is operated to draw the fluid from the first location in the body of the patient.
