1. A catheter balloon, comprising:
a membrane including a proximal end and a distal end;
ten substrates disposed about the membrane, each of the ten substrates including an outer surface, an inner surface, and a respective tail terminating at a respective distal tip disposed proximal to the distal end of the membrane and spaced from the distal end of the membrane;
ten contact electrodes disposed on the outer surface of each of the ten substrates, such that a single contact electrode is disposed on a respective substrate and such that a distal end of each single contact electrode is disposed closer to the proximal end of the membrane than the respective distal tip of the respective substrate;
an adhesive disposed between the inner surface of each of the ten substrates and the membrane; and
a reinforcement disposed atop each respective distal tip and an adjacent portion of the membrane that is disposed distal of the respective distal tip, the reinforcement not being disposed atop any portion of the ten contact electrodes, such that a thickness of the catheter balloon as measured from an inner surface of the membrane, through a respective distal tip, and to an outer surface of the reinforcement is about 0.0075 inches.
