1. A device for providing electrical stimulation to various target sites, the device comprising:
- a housing including a guide positioned in the housing and continuing at least a portion of the length of the housing;
at least one conductor positioned within the housing and continuing through at least a portion of the length of the housing; and
a plurality of addressable stimulation units secured within the housing, wherein each stimulation unit comprises;
a hermetically sealed integrated circuit electrically coupled to the conductor for receiving power and secured to the guide; and
a plurality of electrodes each electrically isolated from the other and each electrically coupled to the circuit, such that the integrated circuit can control the supply of power to each electrode independent of other electrodes,wherein the lead is placed near the various target sites such that each stimulation unit is positioned at one target site and electrical stimulation of each target site is controlled by the integrated circuit of the stimulation unit located proximal to that specific target site.
