Implantable fluid management system for the removal of excess fluid

1. An implantable fluid management system comprising:

an implantable pump comprising an inlet, an outlet, an electromechanical motor and an integrated controller;

a first tube coupled between a peritoneal cavity and the inlet;

a second tube coupled between the outlet and a second body cavity;

a first sensor disposed in fluid communication with at least one of the first and second tubes and operatively coupled to the integrated controller; and

a second sensor disposed in fluid communication with at least one of the first and second tubes and operatively coupled to the integrated controller,

wherein the integrated controller is programmed to activate the electromechanical motor to pump fluid from the peritoneal cavity to the second body cavity when the first sensor detects a first fluid parameter in the peritoneal cavity or the second body cavity higher or lower than a first predetermined threshold, and

wherein the integrated controller is programmed to activate the electromechanical motor to pump fluid when the second sensor detects a second fluid parameter in the peritoneal cavity or the second body cavity higher or lower than a second predetermined threshold.

2. The system of claim 1 , further comprising an external control module configured to be periodically coupled to the implantable pump to transfer energy to the implantable pump.

3. The system of claim 2 , wherein the external control module comprises a driveshaft and a magnet holding arm, the driveshaft transferring power to the magnet holding arm.

4. The system of claim 2 , wherein the external control module transfers data with the implantable pump.

5. The system of claim 1 , wherein the integrated controller is programmed to activate the electromechanical motor to pump fluid at predetermined intervals.

6. The system of claim 1 , wherein the second body cavity comprises a bladder, a stomach, a small intestine, or a large intestine,

wherein the second tube is coupled between the outlet and the bladder, the stomach, the small intestine, or the large intestine, and

wherein the integrated controller is programmed to activate the electromechanical motor to pump fluid from the peritoneal cavity to the bladder, the stomach, the small intestine, or the large intestine.

7. The system of claim 1 , wherein the implantable pump further comprises a housing made of a biocompatible material.

8. The system of claim 7 , wherein the housing comprises anchors selected from the group consisting of barbed insertion pins, a screw threading defined on an outside surface of the implantable pump, staples, sutures, adhesive compounds, a porous solid promoting interstitial cell growth, one or more pins designed to be inserted into the abdominal wall, and combinations thereof.

9. The system of claim 7 , wherein the housing comprises a material promoting fibrotic ingrowth into the housing, and

wherein one or more anti-infective coatings are provided on the housing.

10. The system of claim 1 ,

wherein the first fluid parameter detected by the first sensor is fluid pressure or fluid flow, and the second fluid parameter detected by the second sensor is fluid pressure or fluid flow.

11. The system of claim 1 , wherein the implantable pump and integrated controller are configured to be remotely activated.

12. The system of claim 1 , wherein the implantable pump further comprises a battery.

13. A method of removing fluid from a peritoneal cavity, the method comprising:

detecting, with a first sensor, a first fluid parameter in the peritoneal cavity or a second body cavity higher or lower than a first predetermined threshold;

detecting, with a second sensor, a second fluid parameter in the peritoneal cavity or the second body cavity higher or lower than a second predetermined threshold; and

activating an implantable pump to pump fluid from the peritoneal cavity through a first tube coupled between the peritoneal cavity and an inlet of the pump, through a second tube coupled between the second body cavity and an outlet of the pump, and into the second body cavity,

wherein the activating comprises activating the pump to pump fluid from the peritoneal cavity to the second body cavity responsive to detecting the first fluid parameter higher or lower than the first predetermined threshold, and

wherein the activating further comprises activating the pump to pump fluid from the peritoneal cavity to the second body cavity responsive to the second sensor detecting the second fluid parameter in the peritoneal cavity or the second body cavity higher or lower than the second predetermined threshold.

14. The method of claim 13 , further comprising periodically coupling the pump to an external control module to transfer energy to the pump.

15. The method of claim 13 , further comprising activating the pump to pump fluid from the peritoneal cavity to the second body cavity at predetermined intervals.

16. The method of claim 13 , wherein the second body cavity comprises a bladder, a stomach, a small intestine, or a large intestine, and

wherein the second tube is coupled between the outlet of the pump and the bladder, the stomach, the small intestine, or the large intestine, and

wherein the activating comprises activating the pump to pump fluid from the peritoneal cavity to the bladder, the stomach, the small intestine, or the large intestine.

17. The method of claim 13 , wherein the first fluid parameter detected by the first sensor is fluid pressure or fluid flow, and the second fluid parameter detected by the second sensor is fluid pressure or fluid flow.

18. The method of claim 13 , wherein activating the pump comprises remotely activating the pump.

19. The method of claim 13 , further comprising periodically coupling the pump to an external control module to transfer data therebetween.

20. The method of claim 13 , wherein the pump further comprises a battery.
