Baclofen Pump Surgery Baclofen is a medication commonly used to
decrease spasticity — tight or stiff muscles that may interfere
with voluntary muscle movements — related to multiple sclerosis,
spinal cord injuries, or other neurological diseases. Baclofen
can be taken orally as a pill or delivered directly into an area
of the spine called the intrathecal space. The intrathecal
baclofen pump system delivers the drug directly into the spinal
fluid. The system consists of a catheter (a small, flexible
tube) and a pump. The pump — a round metal disc, about one inch
thick and three inches in diameter — is surgically placed under
the skin of the abdomen near the waistline. Patients with
spasticity who are not responsive to or experience negative side
effects may be candidates for this procedure.
