Abstract:
1. A catheter, comprising: an inflatable balloon assembly having an outer cylindrical sheath and an inner cylindrical sheath intermittently sealed to one another at predefined sections to provide an inflation region, where the inner cylindrical sheath defines a lumen that passes through the inflatable balloon assembly, and where the outer cylindrical sheath defines apertures that connect the inflation region to a containment pocket defined by the outer cylindrical sheath; a cone section defined by an end portion of the outer cylindrical sheath and the inner cylindrical sheath, where the end portions of the outer and inner cylindrical sheaths define both an inflation lumen in fluid tight communication with the inflation region of the inflatable balloon assembly and a cutout that connects with the lumen that passes through the inflatable balloon assembly; an inner balloon waist that extends from the end portion of the inner cylindrical sheath to couple to an inner shaft of the catheter; and an outer balloon waist that extends from the end portion of the outer cylindrical sheath to couple to an outer shaft of the catheter; where the inner balloon waist and inner shaft and the outer balloon waist and the outer shaft define an elongate lumen in fluid tight communication with the inflation lumen through which an inflation medium can flow to inflate the inflation region and pass through the apertures from the inflation region into the containment pocket.
