Abstract

An expandable electrode pad having a flexible and stretchable base member that may be either expanded or compressed to provide proper positioning for a plurality of electrode distal contacts. Portions of the base member may have perforations that allow one or more sections of the base member to be separated and positioned a greater, non-stretchable distance away from the remaining strip of distal contacts. Additionally, the circuit body may comprise a distal cut zone that provides for freedom of movement of the plurality of distal contacts and a proximal perforated zone that eliminates lead wire entanglements while also allowing for the tearing of perforations between adjacent conductive circuits when a greater reach is required for the proper placement of a distal contact.

Claims
