The catheter has a proximal end, a distal end, and a distal end portion. The catheter also has an elastic sleeve on the distal end portion of the catheter and having opposed ends. The sleeve is bonded to the distal end portion in spaced circumferential zones adjacent the opposed ends of the sleeve and along longitudinal lines at least a substantial distance between the zones on opposed sides of the distal end portion. The catheter has an inflation opening beneath the sleeve communicating with the inflation lumen, and at least one drainage eye proximal the sleeve and communicating with the drainage lumen.
