Abstract
An improved intravenous catheter/heparin lock combination having a tip, a body, an IV port and a movable hollow plug; the exterior of the plug having a self-sealing membrane through which needles may be inserted.

A method of using the combination wherein the plug may be positioned to control fluid flow through the port and medications may be administered by needle through the plug independently of fluid flow through the port.
