Abstract
The present invention provides an improved vascular access port comprising a port base with a metallic dish insert molded (or bonded) into the bottom of the reservoir. In one embodiment, a single reservoir is provided. In another embodiment, plural reservoirs are provided. The metallic bottom of the reservoir provides a hard surface that will resist abrasion and puncture by the access needles used to infuse medication or withdraw blood. Additionally, the single and dual ports can include exit ports that are intended to better anatomically fit into the subcutaneous areas around muscle tissue.
