First Claim
Patent Images
1. An implantable fluid management system for draining fluid to a bladder of a mammal comprising:
- a tube member having a first end, a second end, and a length which defines a lumen therethrough;
a pump fluidly coupled to the first tube member; and
an integrated mechanism in fluid communication with the tube, wherein the mechanism is configured to ensure uni-directional flow;
wherein the mechanism comprises a passive ball-valve mechanism.

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.
