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 first pressure sensor disposed in fluid communication with the first tube and operatively coupled to the controller;
a second tube coupled between the outlet and a bladder; and
a second pressure sensor disposed in fluid communication with the second tube 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 bladder responsive to the first pressure sensor detecting a fluid parameter in the pleura exceeding a first predetermined threshold and the second sensor detecting a fluid parameter in the bladder 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 pleura, the method comprising:
-
subcutaneously implanting a pump, a first tube, a first pressure sensor, a second tube, and a second pressure sensor such that the first tube is coupled between the pleura and an inlet of the pump, the first pressure sensor is disposed in fluid communication with the first tube, the second tube is coupled between a bladder and an outlet of the pump, and the second pressure sensor is disposed in fluid communication with the second tube; activating the pump to pump fluid from the pleura to the bladder responsive to the first pressure sensor detecting a fluid parameter in the pleura exceeding a first predetermined threshold and the second sensor detecting a fluid parameter in the bladder lower than a second predetermined threshold. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
