Is Certas valve MRI compatible?
Testing shows that the valve mechanism is resistant to unintended changes in the setting in a 3 Tesla MRI. However, the clinician should confirm the valve setting after a magnetic resonance imaging (MRI) procedure.
Are programmable shunts MRI safe?
If the shunt is known not to be a programmable shunt, then 1.5T and 3T MRI may safely proceed. If it is established that a shunt is a programmable device, then follow the instructions outlined in the instructions for use for that particular device.
What is a Codman Certas valve?
The CODMAN CERTAS® Plus Programmable Valve is an implantable device that provides constant intraventricular pressure and drainage of CSF for the management of hydrocephalus. The CODMAN CERTAS® Tool Kit allows the noninvasive reading or adjustment of the valve setting.
What is a Certas valve?
The CERTAS Plus Programmable Valve allows a surgeon to non-invasively change the opening pressure to one of eight performance settings, which range from 1 (low pressure) to 7 (high pressure), plus performance setting 8, which is a “Virtual Off.” This programmability may negate the need for revision surgery to alter the …
What is a Codman shunt?
The Codman Hakim Programmable Valve offers the ability to optimize the opening pressure of a shunt system before and after implantation. a shunted patient’s condition will often change over the course of their treatment making pres- sure changes necessary.
What is a programmable VP shunt?
A programmable shunt has an adjustable valve which prevents the fluid from moving in the wrong direction and only lets fluid drain when the pressure is too high.
Can I have an MRI if I have a VP shunt?
Some types of programmable VP shunts aren’t affected by MRI scans. Ask your neurosurgeon or nurse practitioner (NP) if your shunt will need to be reprogrammed after MRI scans. You don’t need to take any precautions if you’re having a computed tomography (CT) scan or x-ray.
Are all VP shunts MRI safe?
All currently produced programmable shunt systems including anti-siphon devices are considered MR Conditional up to 3.0T. In addition to exposure to MRI fields, patients are warned that devices such as cellphones and headphones be kept at least 5 cm (2″) from the valve mechanism.
What is Siphonguard?
SIPHONGUARD® is the only dual pathway anti-siphon and flow-control device in which both pathways function in concert. During normal flow, both the primary and secondary pathways are open. When excessive flow is detected, the primary pathway closes and flow is diverted to the high resistance secondary pathway.
What is a Codman?
: a ship used in fishing for cod.
Can you have an MRI with a VP shunt?
Can I have an MRI with a VP shunt?
When was the Codman Certas programmable Valve approved?
The Codman Certas™ programmable valve was approved for clinical use in both Europe and the US in 2011. The Certas™ is an adjustable shunt with 7 pressure settings that range, according to the manufacturer, from 36 to 238 mm H 2 O.
Is the Codman Hakim programmable valve MR conditional?
The CODMAN HAKIM Programmable Valve (CSF shunt valve, Codman, a Johnson & Johnson Company, Raynham, MA) is “MR Conditional” according to ASTM F 2503. The valve demonstrates no known hazards when an MRI is performed under the following conditions: · MRI can be performed at any time after implantation
What are the pressure settings on the Certas valve?
The Certas™ is an adjustable shunt with 7 pressure settings that range, according to the manufacturer, from 36 to 238 mm H 2 O. An interesting feature of the shunt is an eighth setting with a very high opening pressure (>400 mm H 2 O), that is described as “Virtual Off”.
Is the Codman Certas Management System ( TMS ) safe?
Magnetic Resonance Imaging (MRI) Information The CODMAN CERTAS Therapy Management System (TMS) is considered “MR Unsafe” in accordance with the American Society for Testing and Materials (ASTM) Standard F2503-05. Do not use the TMS in the MR suite.
