Abstract
A catheter balloon includes a membrane having a proximal end and a distal end. A plurality of substrates are bonded about the membrane. The ability of a bond's ability to withstand repeated stresses during use may be improved by using a reinforcement or a stress relief, while also minimizing the overall thickness of the balloon proximate to its distal end. The reinforcement may comprise a portion of an unassembled membrane. Alternatively, the reinforcement may comprise an adhesive-margin tip. The stress relief may be a serpentine portion of a distal tail of a substrate.
