Patent number: 8715229Abstract: 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.Type: GrantFiled: March 28, 2011Date of Patent: May 6, 2014Assignee: Bard Peripheral Vascular, Inc.Inventors: William F. Davies, Jr., Lanny R. Pepper, Kelli L. Hayes
