Abstract: A reservoir and method for manufacturing a method may be provided, the reservoir may include a first side piece, a second side piece, an inner fold piece and a reservoir fitting. The first side piece may be sealed to the second side piece with a top seal and a first side seal and a second side seal. The inner fold piece may be sealed to the first side piece and the second side piece through the first side seal, the second side seal, and a bottom seal. The top seal may include a fitting opening and the reservoir fitting may be fit into the fitting opening. The reservoir may contain a volume sensing system. The reservoir may be designed to shape and form to be optimized anatomically so as is to empty and fill reliably without any concern for neighboring organ impingement or compression.

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.
