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 purpose of this study is to provide a single reference for the identification of programmable shunt valves and the Ajnr.org A common concern with shunt function is the over- or underdrainage resulting from the mismatch of opening pressure of the valve to the needs of the patient. 7 To address this issue of mismatch without the need for reoperation, programmable valves that allow clinicians to change the setting of the opening pressure were designed. Syringoperitoneal shunting with a programmable shunt valve was safe and effective for clinical control of syringomyelia associated with extensive SAA. Long-term follow-up is mandatory to monitor for shunt dysfunction and mechanical trouble.

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. We have never noticed any malfunction in correlation to MRI scans up to 1.5 Tesla yet.

Affiliation 1 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. We have never noticed any malfunction in correlation to MRI scans up to 1.5 Tesla yet. There is possibility to identify the opening pressure type of the valve in X-ray (low, medium, high pressure types of valves).
