A targeted drug delivery system delivers pain medication directly to the fluid around the spinal cord, in an area called the intrathecal space.
The system includes a drug pump that is connected to a thin, flexible tube called a catheter. Both the pump and the catheter are fully implanted under the skin.
Because the pump releases medication directly to the pain receptors near the spine instead of going through your circulatory system, pain relief can be achieved with a small fraction of the oral medication dose.
The pump is a round metal device about the size of a hockey puck that is surgically implanted beneath the skin of your abdomen.
