Patent ID: 7599737

Claim:
A medical device for electrical stimulation of neural tissue and controlled drug delivery comprising: an implantable drug delivery module which comprises a substrate having a plurality of reservoirs, a release system contained in each of the reservoirs, wherein the release system comprises at least one drug, a plurality of discrete reservoir caps, each being in register with an opening of one of the reservoirs, separating the release system from an environment outside of the reservoirs, and means for disintegrating one or more of the reservoir caps by electrothermal ablation to release the at least one drug from one or more of the reservoirs; a neural electrical stimulator which comprises a signal generator, and at least one stimulation electrode for operable engagement with a neural tissue of a patient, wherein the at least one stimulation electrode is connected to the signal generator; and at least one microcontroller for controlling operational interaction of the drug delivery module and the neural electrical stimulator.
