How does a Medtronic Strata valve work?
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.
How does a programmable VP shunt work?
A VP shunt is a device that’s placed in your body during a surgery. The shunt takes the CSF out of your brain and moves it into your abdomen (belly), where it’s absorbed by your body. This lowers the pressure and swelling in your brain. A one-way valve and reservoir that controls the flow of CSF.
Are non programmable shunts MRI safe?
If the shunt is known not to be a programmable shunt, then 1.5T and 3T MRI may safely proceed.
How do they adjust a shunt at the brain?
Medtronic Neurosurgery makes devices called shunts to treat this condition, which use an implanted, adjustable valve to drain the excess CSF. Their Strata® valves contain a small magnetic rotor that can be rotated by an external magnet to adjust the appropriate CSF pressure for a patient.
How do I check my shunt settings?
The only sure way to know if an adjustable shunt valve setting has changed is to have the pressure setting checked by a physician with an X-ray or specialized magnetic tool known as a shunt checker. Only a qualified physician should check your shunt valve setting.
What can’t you do with a shunt?
However, people with LP shunts should avoid any activity which involves twisting at the waist, as this can dislodge the shunt.
- Martial arts. Any activity that involves being grabbed around the neck is not advised, as the shunt tubing in the neck can crack.
- Rugby.
- Gymnastics and dance.
- Water sports.
- Golf.
- Other activities.
How much does a shunt revision cost?
Shunt Supply Costs
| Cost | Programmable | Fixed |

| Shunt replacement | $3206 (2906–3578) | $1601 (1435–2186) |

| Total cost per patient | $3438 (2938–3876) | $1504 (753–1584) |
What is a non programmable shunt?
The amount of CSF your VP shunt drains depends on its pressure setting. With a nonprogrammable VP shunt, your neurosurgeon will choose the pressure setting before the shunt is placed. The setting can’t be changed after the nonprogrammable VP shunt is in place.
What are strata adjustable pressure valves used for?
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.
What is a strata valve in a shunt?
Overview. 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.
What is a Medtronic strata valve?
The Strata ® Valve from Medtronic is part of a Ventricular shunt system used to treat the symptoms of hydrocephalus . It is an adjustable flow-control valve. The Strata valve has 5 settings or P/L, ranging from 0.5 to 2.5.
What is the P/L of a strata valve?
The Strata valve has 5 settings or P/L, ranging from 0.5 to 2.5. Each performance level corresponds to a range of opening pressures and flow rates; generally, a lower performance level corresponds to a lower opening pressure. The range of opening pressures is between 15 and 170 mm H2O.
