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 mediport is a small reservoir covered with a rubber or silicone disk which is placed into a small pocket on the patientsâ upper chest or arm. A thin catheter is attached to this reservoir and tunnels under the skin entering a vein and continuing centrally into a larger vein in the chest. mediport is a small reservoir covered with a rubber or silicone disk which is placed into a small pocket on the patientsâ upper chest or arm.
