An adapter for use on a suction lumen of a catheter is disclosed. The adapter is capable of extending the suction capabilities of the catheter to a point distal to a suction port in the catheter. The adapter is at least partially inserted into the catheter. The adapter contains a plug and a duct. The duct has an inlet and an outlet. The duct effectively extends the reach of a suction source and the plug is adapted to seal the catheter between the adapter and the distal end.
