    Abstract: 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.

    Abstract: A semi-compliant fiber-reinforced medical balloon having a folded wall thickness of from about 0.0010 to about 0.0060 inches and a rated burst pressure of at least 15 atmospheres and exhibiting compliance in the radial direction of from 0.5% expansion per atmosphere to rated burst pressure of the balloon includes a base balloon formed from a semi-elastic polymer about 1.0% expansion per atmosphere when pressurized from a fully inflated diameter to the material having an elongation to break of from about 10% to about 20%, a fiber layer is disposed over the base balloon with fibers having an elongation to break of from about 10% to about 20% and an outer layer formed from a semi-elastic polymer material having an elongation to break of from about 10% to about 20% disposed over the fiber layer.

    Abstract: A non-compliant fiber-reinforced medical balloon comprises a first fiber layer and a second fiber layer embedded in a continuous matrix of thermally-weldable polymer material defining a barrel wall, cone walls and neck walls. The fibers of the first fiber layer have a pattern of different lengths and are divisible into a first group and a second group based on length. The length of the fibers of the second group varies progressively in accordance to their proximity to the fibers of the first group; the fibers of the second group closest to the fibers of the first group being longer than the fibers of the second group further from the fibers of the first group. The fiber of the second fiber layer winds circumferentially around the longitudinal axis of the balloon substantially over the entire length of the balloon.

    Abstract: A rapid exchange balloon dilation catheter includes a catheter shaft with a proximal tubular member defining a proximal inflation/deflation lumen for conveying fluids therethrough with a distal portion of the bore of proximal tubular member filled with a fluid-impervious barrier, a distal body extending from the fluid-impervious barrier to the distal end of the shaft, a plurality of distal tubular members defining distal inflation/deflation lumens in fluid communication with the proximal inflation/deflation lumen and extending through the fluid-impervious barrier and the distal body to the distal end of the shaft distal portion, a guidewire tubular member having a bore extending from a side aperture formed in the distal body through the distal body alongside the distal tubular members in a multi-lumen arrangement, and a plurality of stiffening members extending from within the fluid-impervious barrier into the distal body to a point within the shaft distal portion.
