Conductive expandable electrode body and method of manufacturing the same

摘要

A balloon body of an electrode assembly includes an elastomeric non-conductive body expandable to a wide variety of working diameters to accommodate a wide variety of anatomical structures. The elastomeric non-conductive body has a circumferential region and an interior adapted to receive an electrically conductive fluid medium for expanding the elastomeric non-conductive body and transmitting electrical current therethough. A plurality of holes are located in the circumferential region of the elastomeric non-conductive body and a conductive elastomeric material covers the holes and forms one or more conductive regions adapted to transmit electrical current received from the electrically conductive fluid medium through the plurality of holes to adjacent body tissue.
