What is a 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?

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.

What is Codman Hakim shunt?

Description. The Codman® HAKIM® Programmable Valve Lumbo-Peritoneal (L-P) is a single-use implantable device that provides constant intraventricular pressure and drainage of cerebrospinal fluid (CSF) for the management of hydrocephalus.

What is the Hakim valve?

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 VP shunt for hydrocephalus?

A ventriculoperitoneal (VP) shunt is a cerebral shunt that drains excess cerebrospinal fluid (CSF) when there is an obstruction in the normal outflow or there is a decreased absorption of the fluid. Cerebral shunts are used to treat hydrocephalus.

Are brain shunts MRI safe?

NHS GGC MRI safety policy for patients with shunts is as follows. 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.

Are non programmable shunts MRI safe?

How long can you live with a VP shunt?

The average lifespan of an infant’s shunt is two years. Adults and children over the age of 2 may not need a shunt replacement for eight or more years.

Can you get an MRI brain with a VP shunt?

Depending on the model of your programmable VP shunt, the magnet in the MRI scanner may change your shunt’s pressure setting. After your MRI, your shunt’s pressure setting will need to be checked, reprogrammed, or both. You may need to have x-rays to help see if the pressure setting has changed.

What are brain shunts made of?

A shunt usually consists of two catheters and a one-way valve. The valve regulates the amount, flow direction, and pressure of cerebrospinal fluid out of the brain’s ventricles.
