Effect of 3-tesla magnetic resonance imaging on various pressure programmable shunt valves. The 2010 AJNR article by Lollis et al. 1 provides radiographic features (with reference images) of the settings of five common valves (Codman Hakim Programmable Valve, Medtronic Strata, Sophysa Sophy SM8, Sophysa Polaris SPV, and Aesculap Miethke proGAV). The Omni-Shunt System is a non-programmable differential pressure valve.

This is an example of a Sophysa Polaris SPV programmable VP shunt valve. I, … Programmable CSF Shunt Valve. A magnetically programmable CSF shunt valve (Codman Certas Programmable Valve, Codman, a Johnson & Johnson Company), which is in regulatory review, was evaluated in a 3-T MRI environment ().This device is used to regulate intraventricular pressure by means of a ball-and-cone mechanism under the control of a calibrated flat spring and can be noninvasively … According to the AJNR 2010 article by Lollis et al, the Codman Hakim valve is set at 60 mm water (which is the same as the pre MRI setting). Case Discussion This is an example of a Codman Hakim valve. The CODMAN HAKIM Programmable Valve (CSF shunt valve, Codman, a Johnson & Johnson Company, Raynham, MA) includes a valve mechanism that incorporates a flat 316L stainless steel spring in which the calibration is accomplished by a combination between a pillar and a … 2010-07-01 The programmable CSF shunt valve has become an important tool in hydrocephalus treatment, particularly in the NPH population and in pediatric patients with complex hydrocephalus. The Codman Hakim valve is a ventricular shunt valve which can be programmed to open at various CSF fluid pressure. As with previous ventricular shunts, this valve is surgically implanted over the skull near the burr hole for the catheter.

Shunt valves can be set at a fixed opening and closing pressure or can be externally programmed using magnetic tools.16 This is useful for the patient whose CSF drainage needs will change over time. AJNR Am J Neuroradiol.
