Towards an Implantable Pulsed Mode Electrolytic Drug Delivery System

This work presents a prototype of an implantable drug delivery system that delivers pulsed doses of a low solubility drug by pulling bodily fluid into a reservoir with the drug in solid form, allowing the drug to dissolve to its maximum co ncentration, and then ejecting the drug laced fluid back into the tissue. The cyclical actuation of the drug delivery sy stem is performed using an electrolytic pump. By periodical pulsed pumping a stable and constant drug release can be acco mplished, so that the effect of the delivered drug is controllable.
