Abstract:
1. A semi-compliant fiber-reinforced medical balloon that may be inflated and deflated, and when inflated exhibits a moderate change in radial distension across a predetermined range of internal pressures, the balloon having a generally cylindrical barrel wall disposed between tapered cone walls and cylindrical neck walls extending therefrom along a longitudinal axis, the balloon comprising: a base balloon formed from a semi-elastic polymer material having an elongation to break of from about 10% to about 20%, the base balloon defining the cylindrical barrel wall, tapered cone walls and cylindrical neck walls; a first fiber layer disposed over the base balloon, the fibers of the fiber layer having an elongation to break of from about 10% to about 20%; an outer layer formed from a semi-elastic polymer material having an elongation to break of from about 10% to about 20%; and wherein the semi-compliant fiber-reinforced balloon has a rated burst pressure of at least 15 atmospheres and exhibits a compliance in the radial direction of from 0.5% expansion per atmosphere to about 1.0% expansion per atmosphere when pressurized from a fully inflated diameter to the rated burst pressure of the balloon.
