What exactly is a mediport?

An implanted venous access port, also known as a mediport, is a device placed under the skin to deliver chemotherapy treatments. The port is a small container that is normally placed in the upper chest. The port container is attached to a catheter (tube) that enters a large vein (blood vessel). The port is made of plastic or metal with a self-sealing cover over the top. Surgery to install the port only requires local anesthesia and takes about an hour.
