Implantable fluid management system for the removal of excess fluid
First Claim
Patent Images
1. An implantable fluid management system comprising:
- an implantable pump having an inlet, an outlet, an electromechanical motor and an integrated controller, the implantable pump configured to be implanted subcutaneously;
a first tube coupled between a pleura and the inlet;
a second tube coupled between the outlet and an abdomen; and
a sensor disposed in fluid communication with at least one of the first and second tubes and operatively coupled to the controller,wherein the integrated controller is programmed to activate the electromechanical motor to pump fluid from the pleura to the abdomen at predetermined intervals when the sensor detects a fluid parameter in the pleura higher 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 pleura, the method comprising:
-
subcutaneously implanting a pump, a first tube, a second tube, and a sensor such that the first tube is coupled between the pleura and an inlet of the pump, the second tube is coupled between an abdomen and an outlet of the pump, and the sensor is disposed in fluid communication with at least one of the first and second tubes; and activating the pump to pump fluid from the pleura to the abdomen at predetermined intervals responsive to the sensor detecting a fluid parameter in the pleura higher than a predetermined threshold. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
