1. A therapeutic agent delivery system comprising:
- a housing retaining a semipermeable membrane and together with the membrane defining a donor chamber adapted to hold the therapeutic agent, the membrane being made of a material that is substantially impermeable to the therapeutic agent in an ionic form;
an anode and a cathode exposed within the donor chamber such that an electromotive force between the anode and the cathode will alter the electrical charge of the therapeutic agent to permit the agent to pass through the membrane.
