Abstract: Apparatuses and systems for applying electrical stimulation to a site on a patient. In one embodiment, an implantable electrode assembly includes an electrode array carried by a flexible support member. The electrode array can include a first plurality of electrodes spaced apart from a second plurality of electrodes. The first plurality of electrodes can be connected to a first lead line, and the second plurality of electrodes can be similarly connected to a second lead line. The first and second lead lines can be housed in a cable extending away from the support member. A distal end of the cable can include a connector for coupling the lead lines to an implantable pulse generator or other stimulus unit. In operation, the stimulus unit can bias the first plurality of electrodes at a first potential and the second plurality of electrodes at a second potential to generate an electric field proximate to a stimulation site.
