A catheter comprising, a first distal shaft section having a first distal drainage lumen extending therethrough, and a first inflation lumen extending through a wall of the first shaft section. The catheter has an elastic sleeve bonded to a distal portion of the first shaft section in circumferential zones defining a cavity beneath the sleeve communicating with the first inflation lumen. The catheter has a proximal portion comprising a second proximal shaft section having a second drainage lumen extending therethrough, a hollow connector defining a continuation of the second drainage lumen, a side arm having a valve, and a second inflation lumen extending through the side arm from the valve and through the second shaft section to a distal end of the proximal portion. The catheter has a device for locking the first shaft section to the proximal portion while establishing communication between the first and second drainage lumens and between the first and second inflation lumens.
