How does a mediport work? A port consists of a reservoir compartment (the portal) that has a silicone bubble for needle insertion (the septum), with an attached plastic tube (the catheter). The device is surgically inserted under the skin in the upper chest or in the arm and appears as a bump under the skin.
A port is the size of a nickel or a quarter. It can be circular, oblong, or triangle shaped. It is usually placed about an inch below the center of your right collarbone. The port usually raises your skin about Â½ inch above normal. You will most likely be able to feel it through your skin (Figure 2).
