How do you adjust a Certas valve?
The setting of the CERTAS Plus Programmable Valve is changed through the use of an externally applied magnetic field. Applying a specific magnetic field to the adjustable valve mechanism will permit the cam to turn slightly, increasing or decreasing the tension on the spring, and changing the setting of the valve.
What is a Codman Certas valve?
Codman Certas Programmable Valves are single-use implantable devices, designed to drain excess cerebrospinal fluid from the brain and carry it to other parts of the body for the treatment of hydrocephalus (also known as ‘water on the brain’). The valves can be programmed to eight different settings.
Is Certas valve MRI compatible?
This device is safe for patients undergoing MRI procedures.
What is a Codman shunt?
The Codman Hakim Programmable Shunt is an innovative system that gives neurosurgeons the ability to tailor the valve opening pressure to the unique needs of each individual within a range of 18 pressure settings. Hakim is a registered trademark of Hakim USA, LLC and is used under license by Codman & Shurtleff, Inc..
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 strata valve?
Strata® adjustable pressure valves are part of a shunt system used to treat the symptoms of hydrocephalus. A shunt redirects excess cerebrospinal fluid in the brain to another part of the body, allowing the brain’s enlarged ventricles to return to a more normal size.
Can you get an MRI with a shunt?
Your shunt should be reprogrammed within 4 hours after your MRI. 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.
Are all 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.
Where is a VP shunt placed?
The long catheter is placed under your skin, behind your ear, down your neck, and into your abdomen. As the VP shunt drains extra CSF and lessens the pressure in your brain, it may ease some of your symptoms. Some symptoms will stop right after the VP shunt is inserted.
What are the symptoms of VP shunt Overdrainage?
Over-drainage: When the shunt allows cerebral fluid to drain from the brain’s ventricles more quickly than it is produced, the ventricles can collapse, tearing blood vessels and causing bleeding in the brain or blood clot, marked by severe headache, nausea, vomiting, seizure and other symptoms.
When to use the Codman Certas Valve kit?
The CODMAN CERTAS®Tool Kit allows the noninvasive reading or adjustment of the valve setting. CONTRAINDICATIONS These devices are contraindicated in patients receiving anticoagulants or known to have a bleeding diathesis.
What do you need to know about Codman Certas?
CODMAN®CERTAS™TOOL KIT Versatility Allows for a non-invasive reading to assist in monitoring monitoring and adjusting valve pressure 2 Locator Tool options to choose from for optimal alignment with the valve Indicator Tool provides rapid reading of valve setting Lightweight design and portable carrying case CODMAN®SIPHONGUARD® DEVICE
What kind of MRI is needed for Codman valve?
• 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. • Read MRI Information before performing an MRI procedure on a patient implanted with the valve.
How is the setting of the valve determined?
The film must be taken in relation to the valve and not the patient’s anatomy. Reading the valve setting: The valve setting is determined by the Setting Indicator , relative to the Right Hand Side X-ray Marker . Procedure Guide X-RAY OVERLAY TOOL QUICK REFERENCE GUIDE
