Non-compliant medical balloon having braided or knitted reinforcement

摘要

A non-compliant medical balloon comprises a base balloon including a pair of spaced-apart, generally conical end sections and a generally cylindrical center section connected therebetween. A braided fabric sleeve surrounds at least a portion of the base balloon, wherein the sleeve is formed of at least three substantially inelastic fibers intertwined in such a way that no two of the three fibers are twisted exclusively around one another. The sleeve is permanently affixed to the outer surface of the base balloon so as to prevent excessive expansion of the base balloon when the base balloon is internally pressurized.

1. A non-compliant medical balloon comprising:
a base balloon having a longitudinal axis, said balloon including a first section with a first diameter and a second section with a second diameter; and a reinforcement layer comprising a plurality of braided fibers, wherein the braided fibers form a braid angle with respect to one another, and wherein the braid angle at a first location of the reinforcement layer is less than the braid angle at a second location of the reinforcement layer; wherein there is substantially no change in the braid angles when the balloon changes from a deflated state to an inflated state.
