Abstract: A multiple lumen vascular access port including a base, first and second lumens in the base, first and second catheters in communication with the first and second lumens, respectively, a boss in contiguous relationship to the first lumen to permit its identification by feel, metal tubes in the catheters proximate the lumens to prevent leakable puncture of the catheters in the event of penetration of the catheters by a needle, and a tube leading to the second lumen being recessed within a metal portion of the first lumen to prevent access thereto by a needle which might puncture it. The vascular access port can contain more than two lumens.
