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, andwherein 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.

Abstract
An implantable fluid management device, designed to drain excess fluid from a variety of locations in a living host into a second location within the host, such as the bladder of that host. The device may be used to treat ascites, chronic pericardial effusions, normopressure hydrocephalus, hydrocephalus, pulmonary edema, or any fluid collection within the body of a human, or a non-human mammal.

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. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
