Implantable fluid management system for the removal of excess fluid
First Claim
Patent Images
1. A method of draining a fluid from a patient'"'"'s peritoneal cavity to the patient'"'"'s bladder, the method comprising:
- implanting within the patient'"'"'s peritoneal cavity an apparatus comprising an electromechanical pump, a battery and a programmable controller coupled to the electromechanical pump and the battery, the electromechanical pump including an inlet and an outlet;
establishing fluid communication between the peritoneal cavity and the inlet with a first tube and between the outlet and the bladder with a second tube; and
periodically activating the electromechanical pump, responsive to the programmable controller, in an oscillating or pulsatile manner to jar proteinaceous buildup free from within the pump and the first and second tubes to prevent clogging.

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. An apparatus for draining a fluid from a patient'"'"'s peritoneal cavity to the patient'"'"'s bladder, the apparatus comprising:
-
a housing configured for subcutaneous implantation; an electromechanical pump disposed within the housing, the pump having an inlet and an outlet; a first tube having a first end configured to be disposed within the peritoneal cavity and a second end coupled to the inlet; a second tube having a first end coupled to the outlet and a second end configured to be coupled to the bladder; a battery disposed within the housing; and a controller disposed within the housing, the controller coupled to the electromechanical pump and the battery, the controller programmed to periodically activate the electromechanical pump in an oscillating or pulsatile manner to jar proteinaceous buildup free from within the electromechanical pump and the first and second tubes to prevent clogging. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
