RUPTURE-RESISTANT COMPLIANT RADIOPAQUE CATHETER BALLOON AND METHODS FOR USE OF SAME IN AN INTRAVASCULAR SURGICAL PROCEDURE

摘要

The present invention provides a compliant balloon for use with a catheter having an inner compliant inner layer defining a cylindrical lumen encased by a fiber layer including non-braided inelastic fibers imparting integrity to the balloon wall. The balloon further includes radiopaque material which may be disposed over substantially the entire length of the balloon as a coating or by incorporation within the fiber layer or an outer coating layer. The balloon is expandable from a folded deflated state to an inflated state by increasing pressure within the balloon and can be used with saline as the sole inflation medium to allow rapid deflation as compared to use of a balloon with a contrast medium.

主权项

1. A radiopaque balloon for use with an intraluminal catheter, comprising:
(a) an inflation layer, consisting of a compliant polymeric cylinder having a central region ending in opposing conical regions, said cylinder defining an outer surface and an inner lumen for retention of inflation fluid; (b) a fiber layer, consisting of at least two layers of inelastic, braided or non-braided fibers disposed around the length of the inflation layer; (c) at least one coating layer, consisting of at least one adhesive disposed to affix the fiber layer to the inflation layer, wherein at least one adhesive penetrates the fiber layer to form the at least one coating layer; and, (d) a radiopaque material disposed over substantially the entire length of the outer surface of the inflation layer.
