Valve system and method with multi-directional pumping

摘要

An implantable valve system and method of using same, including a housing with a resilient membrane defining a reservoir in fluid communication with at least two ports, and at least a first set of opposing sealing features disposed on upper and lower surfaces within the housing. The membrane is capable of being depressed by a human finger to bring the sealing features together to substantially restrict fluid from passing through at least one of one of the ports, and is capable of being depressed additionally by a rolling motion of the finger to drive fluid through the other of the ports.

1. An implantable valve system comprising:
a housing with a single dome-shaped resilient membrane defining a reservoir in fluid communication with at least two ports and having a longitudinal axis; at least a first set of opposing sealing features disposed on upper and lower surfaces within the housing, the opposing sealing features being disposed in the center region of the reservoir; the single dome-shaped membrane capable of being depressed by a human finger to bring the sealing features together to substantially restrict fluid from passing through at least one of one of the ports and to divide the reservoir into a first pumping chamber and a second pumping chamber; the single dome-shaped membrane further capable of being depressed additionally by a rolling motion of the finger to drive fluid through the other of the ports; and wherein one of the sealing features includes a detent and the other of the sealing features includes a recess to matingly receive the detent.
