The improvement is wherein the cannula has a larger outer cross-section and the duct has a larger inner cross-section starting from the proximal end portion and continuing to a position along the cannula then have the cannula and duct starting at the distal end portion and continuing to the position. The position is located distally from the hub. A reinforcing tube is provided having an outer surface matingly held within the duct and an inner passageway, the tube extending from the proximal end portion distally beyond the hub towards the position. That portion of the cannula which is reinforced by the reinforcing tube is prevented from kinking and/or deforming.
