Patent ID: 8313601

Claim:
A method of making non-compliant fiber-reinforced medical balloon that may be inflated and deflated, and when inflated exhibits minimal 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 method comprising: a) coating a mandrel with a solution including a thermally weldable polymer to begin a balloon layup by one of spraying, dipping or brushing the solution onto the mandrel; b) affixing a patterned sock sheet over the coated mandrel; c) winding hoop fibers over the sock sheet; d) wrapping one of a film or tape of a thermally weldable polymer material over the sock sheet and hoop fibers; and e) heating the layup to weld the thermally weldable materials together to encapsulate the fibers of the sock sheet and hoop fibers in a continuous matrix of the thermally weldable material.
