Claim Text:
1. A system for generating and sensing electrical energy to and from tissue within a mammalian body comprising: (a) an electrical generator configured to produce and sense electrical energy to and from said tissue; (b) a lead coupled to said generator configured to be insertable in proximity to said tissue, said lead having a lead axis line; (c) at least one expandable electrode coupled to said lead, said expandable electrode being radially displaceable with respect to said lead axis line defining a longitudinal direction for contiguous contact with a wall of said tissue, said expandable electrode including at least two arcuate arm members extending transverse said longitudinal direction from opposing lateral sides of said lead and having overlapping sections prior to said radial expansion of said at least one electrode, said arm members disposed in a singular plane each with respect to the other; and (d) a balloon catheter for insert within an opening formed by said at least one electrode having an arcuate contour forming said opening whereby said balloon catheter contacts an inner periphery of said at least one electrode and radially displaces said at least one electrode upon inflation of a balloon formed on said balloon catheter.
