A shaft and a connector with a side arm which when assembled comprise a catheter. The connector has an inflation lumen in its side arm and an axial bore through the body of the connector, the inflation lumen and the bore being in fluid communication. The bore has three annular channels therein. Two of the channels are arranged to receive adhesive through the wall of the connector, and the third channel is intermediate the other two is in fluid communication with the inflation lumen of the side arm. The shaft has a drainage lumen and an inflation lumen therein. A pair of openings to the inflation lumens, are disposed in the shaft, corresponding to two of the channels in the connector. Adhesive injected into the outer channels bonds the shaft to the connector and seals the proximalmost orifice of the inflation lumen in the shaft. The other opening provides fluid communication between the inflation lumen of the shaft and the inflation lumen of the side arm.
