Abstract

An electrode support structure has spline elements radiating from a center hub in a circumferentially spaced relationship. The spline elements include terminal ends spaced from the hub which are joined to a base member to form a three dimensional structure for supporting electrodes. The center hub lies essentially within the envelope of the spline elements to present a surface free of projections that can poke into and cause tissue trauma during use.
