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 may also be called a BardPortÂ®, a MediportÂ®, a PowerPortÂ®, or a Port-A-CathÂ®. There are many different ports available (Figure 1). Your doctor will choose the one that is best for you and your treatments. A port is like an artificial vein. There are many reasons to have a port placed. Some people have veins that are difficult to start an intravenous (IV) for medicine or draw blood from for tests. Some people need to receive chemotherapy continuously for several days. Sometimes, chemotherapy must be given in a vein larger than the ones in your arms.
