FDA Product Code JXG: Shunt, Central Nervous System And Components

Hydrocephalus is managed with shunt systems that divert excess cerebrospinal fluid. FDA product code JXG covers central nervous system shunts and their components.

These implanted systems typically consist of a ventricular catheter, a valve mechanism, and a distal catheter that diverts excess cerebrospinal fluid from the ventricles to the peritoneal cavity, pleura, or atrium. Programmable valves allow non-invasive adjustment of drainage pressure.

JXG devices are Class II medical devices, regulated under 21 CFR 882.5550 and reviewed by the FDA Neurology panel.

Leading manufacturers include Codman & Shurtleff, Inc., Holter-Hausner Intl. and Medtronic Neurosurgery.
