Abstract
A flexible support for a thin electrically conductive electrode has an edge around its major surfaces. One or more circumferential frames on the support capture the edge of the electrode. An under cut on the frame holds the edge. A membrane is integral with the one or more frames to extend and be coextensive with each. The membrane is thin to allow expansion in deference to each frame. The support is a flexible polymer one with a percent of elongation in the range of 500% to 1500%. The one or more frames and the membrane form a balloon with interior and exterior surfaces with an inflation port therethrough. The under cut on each frame is disposed to substantially enclose the edge on the exterior surface. The membrane expands upon inflation of the balloon. Each frame has a window opening to a recess peripherally surrounded by the under cut and a wall therein to abut the edge. The window opening is shaped as the major surface of the electrode while sized slightly smaller to define the under cut. The flexible polymer is an elastomeric material with a high dielectric with a temperature resistance of at 0 least 100 degrees centigrade. Adhesive bonds one major surface in the frame. The m…
