Claim:
1. A medical balloon having a working length and comprising a balloon wall defining a chamber, wherein at least a portion of the balloon wall comprises a material that is longitudinally compressed; wherein the medical balloon is configured to be inflated to a pressure of at least 4 atm and is semi-compliant to non-compliant when inflated to a pressure of at least 4 atm; wherein the longitudinally compressed material allows the balloon wall to be bent to an orientation imparting at least 20% total strain to the balloon wall, and when the medical balloon is inflated to a pressure of at least 4 atm and not subjected to a bending force, the medical balloon will assume an essentially straight configuration, and further when the medical balloon is inflated to a pressure of at least 4 atm and is subjected to a bending force of 20% total strain, the medical balloon, along a portion of the working length, defines an inner arc and an outer arc and a portion of balloon wall extending along the inner arc undergoes at least 5% compressive strain.
