Abstract
A non-compliant medical balloon may be changed from a deflated state to an inflated state by increasing pressure within the balloon. The non-compliant medical balloon is composed of a woven fabric layer composed of at least two woven fabric fibers forming an angle. The angle remains substantially unchanged when the balloon changes from a deflated state to an inflated state.
Claims20
A non-compliant medical balloon comprising:
- a base layer;
- a first fabric layer comprising a plurality of substantially inelastic fibers, said first fabric layer being a woven fabric layer;
- a second fabric layer comprising at least one substantially inelastic fiber, said second fabric layer distinct from the first fabric layer;
- and
- at least one adhesive layer for maintaining the first fabric layer or the second fabric layer in place;
- wherein the balloon includes at least one fold in a deflated configuration, and wherein said at least one fold is not present in an inflated configuration.
A non-compliant medical balloon having a folded configuration and an inflated configuration, the balloon comprising:
- a base balloon;
- a first fabric layer comprising a plurality of substantially inelastic first fibers, said first layer adhesively attached to the base balloon;
- a second fabric layer comprising a plurality of substantially inelastic second fibers, distinct from the first fabric layer;
- and
- an outer polymeric coating.
A method of forming a non-compliant balloon comprising:
- providing a base layer comprising a substantially inelastic polymer;
- covering the base layer with a first fabric layer comprising a plurality of substantially inelastic first fibers;
- providing a second fabric layer comprising at least one second fiber;
- and
- applying an outer polymeric coating.
