intrathecal baclofen pump
Implantable device that delivers baclofen medication directly into the cerebrospinal fluid to manage severe spasticity in spinal cord injury patients.
Full Definition
An intrathecal baclofen pump is a surgically implanted programmable device designed to deliver precise doses of baclofen medication directly into the intrathecal space surrounding the spinal cord. This targeted drug delivery system is primarily used for managing severe spasticity in patients with spinal cord injuries, multiple sclerosis, or other neurological conditions where oral medications prove inadequate. The system consists of a titanium pump reservoir implanted in the abdominal wall and a catheter that delivers medication to the cerebrospinal fluid. Regular refills and programming adjustments are required, and potential complications include catheter malfunction, infection, or drug withdrawal syndrome. Editors should note that this represents a distinct treatment modality from external baclofen therapy and requires specialized neurosurgical expertise.
Usage
Usage note: Commonly abbreviated as ITB pump in clinical contexts; maintain consistency in terminology throughout documents.
