Abstract:
1. A non-compliant medical balloon, where the non-compliant medical balloon may be changed from a deflated state having a folded configuration to an inflated state having a smooth, unfolded configuration by increasing pressure within the balloon, comprising: an inner wall formed of a flexible but substantially inelastic polymer material defining two spaced-apart cone portions and a barrel portion disposed therebetween; an adhesive layer applied directly to the outer surface of the inner wall; a woven fabric layer including at least one substantially inelastic fabric fiber interwoven with a second fabric fiber in a single fabric layer, wherein said first fabric fiber and said second fabric fiber define angles where they cross one another; wherein the balloon can change between a deflated state having a folded configuration with balloon folds on the outer surface to an inflated state having an unfolded configuration with a substantially smooth outer surface by increasing the pressure within the inner wall; and wherein the fibers of the woven fabric layer are affixed to the inner wall by the adhesive layer such that the angles between the first fabric fiber and the second fabric fiber remains substantially unchanged when the balloon changes from the deflated state to the inflated state.
