Abstract

A bidirectional electroosmotic pump may be provided. The bidirectional electroosmotic pump may be made of materials that are biocompatible and non-ferrous. The bidirectional electroosmotic pump may be part of an implantable medical device for the purpose of medicine delivery. The bidirectional electroosmotic pump may contain a working fluid and may facilitate the delivery of a separate payload fluid. In an exemplary embodiment, the bidirectional pump may contain bellows which may allow the pump to deliver the payload fluid through a series of valves and/or catheters. In another embodiment the bidirectional electroosmotic pump may contain a pump sensing mechanism to monitor the state of the pump.
