Abstract
A balloon of a balloon catheter must be able to withstand fatigue to its componentry caused by multiple cycles of repeat motions, such as deployment from a lumen of the catheter, expanding the balloon, collapsing the balloon, and withdrawal of the balloon into the lumen. The catheter balloon may include plurality of electrode substrates, each including a plurality of tails. A reinforcement component, which may be a portion of another balloon, may be disposed over at least some of the plurality of tails and attached to the membrane. Where tails are provided on the proximal and distal ends of the balloon, two reinforcement mechanisms may be used.
