1. A medical balloon having a longitudinal axis, the medical balloon comprising:
a balloon wall comprising a semi-compliant to non-compliant balloon comprising a polymeric material, the polymeric material being anisotropic and oriented such that the balloon wall has a longitudinal stiffness that is less than a radial stiffness;
a nominal diameter of between about 9 mm to about 12 mm, a nominal pressure at or below 6 atm and a working pressure range that spaces the nominal inflation pressure to a rated burst pressure, where the balloon exhibits while in a curved configuration requiring 16% total strain, less than a 3N increase mean straightening force when inflated across the working pressure range and wherein the medical balloon exhibits less than a 10N mean straightening force when inflated at the rated burst pressure, while in a curved configuration requiring 16% total strain.
