Codman Announces New MRI-Resistant Hydrocephalus Valve

The Seventh Meeting of the International Society for Hydrocephalus and CSF Disorders  sees J&J’s, Codman Neuro company announcing a new MRI-resistant programmable valve with eight different pressure settings, including a ‘virtual off’ setting, for the treatment of hydrocephalus.


Hydrocephalus is estimated to affect more than one million children and adults in the United States. It is characterized by an excessive accumulation of cerebrospinal fluid (CSF) that causes the ventricles of the brain to enlarge and the pressure inside the head to increase, which can lead to a range of harmful effects including damage to brain tissue and impairments in cognitive and motor function.

The most common treatment for hydrocephalus is the surgical implantation of a valve or shunt, a flexible tube placed into the brain to divert excess CSF from the head to the abdomen. With the new CODMAN CERTAS® Plus Programmable Valve, neurosurgeons are able to pre-operatively choose from eight low-to-high pressure settings to control the rate of drainage of CSF from the brain. The valve pressure can be read and adjusted non-invasively or even turned ‘virtually off’ (valve pressure consistently above 400 mmH20) any time after implantation using the CODMAN CERTAS Tool Kit, which employs magnetic force to change settings.

The CODMAN CERTAS Plus Programmable Valve is resistant to unintended changes in the valve setting in a 3 Tesla magnetic resonance imaging (MRI) system and may be integrated with Codman Neuro’s BACTISEAL® Antimicrobial Catheter and/or SIPHONGUARD® Anti-Siphon Device, depending on surgeon preference.
