Claim:
1. An implantable electrolytic pump comprising: a drug chamber for containing a liquid to be administered; a cannula in fluid communication with the chamber; an electrolysis chamber comprising first and second electrodes; circuitry configured for applying a voltage between the first and second electrodes to facilitate electrolysis of a material in the electrolysis chamber to thereby produce a gas and force the liquid to flow from the drug chamber to the cannula; and a catalyst in the electrolysis chamber for catalyzing recombination of the produced gas to form the material, thereby reversing the electrolysis; wherein the circuitry is further configured to apply a small trickle charge to the first and second electrodes to prevent reversing the electrolysis and hold the pump in place.
