The shaft has an elongated section extending between the ledges and recessed from the bonding surfaces, with the shaft section defining an inner part of a cavity communicating with the inflation lumen intermediate the ledges. The catheter has an annular sleeve of elastic material having a thickness approximately equal to the distance between the bonding surfaces and the outer shaft surface adjacent the ledges, with the sleeve having a length approximately equal to the distance between remote ends of the ledges, and with opposed ends of the sleeve being bonded to the bonding surfaces circumferentially around the ledges.
