An inflatable medical balloon having a determined pre-inflation length, restricted longitudinal or radial expansion characteristics, a circumference and a longitudinal axis comprising:
�� a matrix material, said matrix material characterized as being semi-compliant;
�� and having a plurality of cores therethrough, said cores being evenly distributed about the circumference of the balloon and being composed of one or more materials which are characterized as being stronger than the matrix material and having a bulk elongation less than the matrix material when the one or more materials are oriented in the direction of the longitudinal axis, and the matrix material and the core material operatively adhering to one another.
