A balloon of a balloon catheter must be able to withstand fatigue to itscomponentrycaused by multiple cycles of repeat motions, such as deployment from a lumenof the catheter,expanding the balloon, collapsing the balloon, and withdrawal of the ballooninto the lumen. Thecatheter balloon may include plurality of electrode substrates, each includinga plurality of tails.A reinforcement component, which may be a portion of another balloon, may bedisposed over atleast some of the plurality of tails and attached to the membrane. Where tailsare provided on theproximal and distal ends of the balloon, two reinforcement mechanisms may beused.
