Gary, The Baclofen pump is a device about the size of a hockey puck. It is surgically inserted under the skin of the stomach or side. There is a catheter leading from the pump, around to the back, and inserted directly into the spine. The pump is programmed to administer a certain amount of medication, every so often. All of the programming is done by putting a small device on the outside of those pump, over the skin, which is connected to a programmer which looks like a large PDA. It is all done by touch screen. The medicine in the pump has to be replaced every six months. This is done by inserting a needle into the pump and withdrawing the medication, and replacing it with fresh medicine. Because the medicine goes directly into the spine, and not throughout the whole body, it uses a much smaller dose and the side effects are at a minimal. I hope this helps you to understand the pump a little more. Feel free to ask any other questions.
