Abstract:
1. An inflatable medical balloon which is mounted on a catheter, and has a determined preinflation length, restricted longitudinal and radial characteristics, a circumference and a longitudinal axis, composed of a micro-composite material comprising a polymer matrix component with a polymer fibril component distributed in the polymer matrix component, the polymer fibril component having micro-fibers oriented substantially parallel or diagonally to the longitudinal axis of the balloon, the polymer fibril component composed of one or more members selected from the group consisting of rigid-rod thermoplastic, semi-rigid rod thermoplastic, liquid crystal polymer, which are stronger than the matrix material and have bulk elongation between 50% and 150%, which is less than the matrix material and the fibril component and the matrix component operatively adhere to one another.
