1. An electrophysiology probe comprising:
a tubular member extending along a longitudinal axis from a first end to a second end;
a first expandable membrane having an outer surface and an inner surface disposed about the longitudinal axis, the first expandable membrane having a first expandable membrane portion being coupled to the second end of the tubular member and a second expandable membrane portion spaced apart from the first expandable membrane portion along the longitudinal axis, the first expandable membrane configured to be expanded from a compressed shape to a balloon shaped member;
a plurality of electrodes disposed on the outer surface of the first expandable membrane;
one or more wires connected to each of the plurality of electrodes, each of the one or more wires extending from the tubular member to a respective electrode of the plurality of electrodes;
a second expandable membrane that encapsulates the one or more wires between the second expandable membrane and the first expandable membrane so that the one or more wires are constrained between the first and second expandable membranes with the plurality of electrodes exposed to an external ambient environment; and
a third expandable membrane disposed proximate the first expandable membrane portion so that the third expandable membrane encircles a portion of the first expandable membrane about the longitudinal axis,
wherein the third expandable membrane encapsulates a portion of a substrate for each of the plurality of electrodes between the first expandable membrane and the third expandable membrane, and
wherein the third expandable membrane is spaced apart from the second expandable membrane along the longitudinal axis.
