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.
The intrathecal pump is a small device that is surgically implanted under the skin. This device has a tiny battery-powered pump that is programmable and refillable. The nurse refills the pump every 1-3 months using a syringe and needle. The pump is connected to an intrathecal catheter that delivers tiny concentrated amounts of pain medicine to the spinal fluid. How is the intrathecal pump implanted? Before the permanent device is implanted, the pain management specialist will have you take an epidural trial.
