There is disclosed a system and method for allowing use within a body of devices having material not known for its biocompatibility with the body. In one embodiment, a magnetically controlled solenoid/valve is used where portions of the valve are directly in contact with compositions that are to be delivered to a target site. Advantage is taken of an existing solenoid/valve having chromium alloy parts by coating the portions of the valve that contact the deliverable composition with a known biocompatible material having good wear resistance. In one embodiment, titanium nitride (TiN) is used as the coating material.
