Implantable fluid management system for the removal of excess fluid
First Claim
Patent Images
1. An implantable fluid management system comprising:
- an implantable pump comprising a gear pump and an integrated controller, the gear pump having an inlet and an outlet;
a first tube coupled between a peritoneal cavity and the inlet;
a second tube coupled between the outlet and a second body cavity; and
a 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 gear pump to pump fluid from the peritoneal cavity to the second body cavity when the sensor detects a fluid parameter in the peritoneal cavity or the second body cavity higher or lower than a 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 sensor, a fluid parameter in the peritoneal cavity or a second body cavity higher or lower than a predetermined threshold; and activating an implantable pump comprising a gear pump and an integrated controller to pump fluid from the peritoneal cavity through a first tube coupled between the peritoneal cavity and an inlet of the gear pump, through a second tube coupled between the second body cavity and an outlet of the gear pump, and into the second body cavity, wherein activating the implantable pump comprises activating the implantable pump to pump fluid from the peritoneal cavity to the second body cavity responsive to detecting the fluid parameter higher or lower than the predetermined threshold. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
