1. An implantable electrode device, comprising: a) a carrier extending along a first carrier length from a proximal carrier portion to a distal carrier portion having a distal carrier end; b) a first electrical subsystem, comprising: i) at least one electrode site; ii) an electrode substrate supporting the at least one electrode site, wherein at least a portion of the electrode substrate supporting the at least one electrode site is woven with the carrier so that the at least one electrode site has an exposed surface facing outwardly from the electrode substrate opposite the carrier; and iii) an electrical connector extending from the at least one electrode site to a proximal connector portion adjacent to the proximal carrier portion; and c) wherein the carrier is of a bioresorbable material that is absorbable into body tissue after implantation of the electrode device comprising the carrier and the first electrical subsystem, thereby leaving the at least one electrode site facing outwardly toward the body tissue from the supporting electrode substrate.
