1. A dialysis catheter assembly comprising:
- a hub;
a first and a second extension tube each coupled to the hub;
an elongated main body having a proximal end and a distal end, the proximal end of the elongated main body coupled to the hub, the elongated main body defining a first and a second longitudinal lumen and at least one side-port, the first and second longitudinal lumens in fluid communication with respective first and second extension tubes, and the at least one side port in fluid communication with at least one of the first and second longitudinal lumens; and
a balloon disposed on the elongated main body proximal to and adjacent the at least one side-port when the balloon is in an uninflated state, wherein the balloon is inflatable in a distal direction to extend at least partially over the at least one side-port so that the balloon is at least partially coextensive with the at least one side-port when the balloon in an inflated state.

Abstract
A catheter assembly includes an elongated main body defining two or more longitudinal lumens including distally positioned openings. One or more side-ports are defined in the main body communicating with at least one of the two or more longitudinal lumens. The catheter assembly also includes an inflatable balloon disposed around a portion of the main body. The inflatable balloon includes a distal end disposed substantially adjacent to a proximal side of one or more side-ports. The inflatable balloon in the inflated state is adapted to extend at partially over the one or more side-ports.
