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.
Noninvasive pressure setting adjustment may reduce the need for revision surgeries.
Optional Delta™ chamber allows pressure in the brain to be maintained within a certain range, regardless of body position.
AccessiblReservoir dome allows your doctor to sample cerebrospinal fluid and test shunt function.
Contoured reservoir base mimics the curvature of the skull, providing a better fit.
No X-ray Verification
Easy-to-use hand tools allow for verification of pressure setting without the need of an x-ray.
The valve is placed behind the ear or near the top of the head. It’s attached to a ventricular catheter on one side, and a distal catheter on the other.
The device is not shown actual size. Other sizes may be available.
Height 0.63" (1.6 cm)
Width 1.85" (4.7 cm)
Depth 0.28" (0.7 cm)

Caution: FDA (USA) law restricts this device to sale by or on the order of a physician. Refer to product package insert for instructions, warnings, precautions and complications.
Since the Strata valve includes a magnet, special precautions must be observed around magnetic sources such as some audio headphones. Common environmental levels of electromagnetic radiation generated by security scanners, metal detectors, microwave ovens, high voltage lines, computers, and transformers will not affect the valve.
If a device is known to contain a magnet, keep it away from the immediate valve location i.e., the skin next to the valve. For patients undergoing an MRI procedure, it will be necessary for the doctor to check the valve pressure setting afterwards and readjust it if necessary.
