FDA has cleared a Cerebrotech Medical Systems 510(k) for the Cerebrotech Visor, previously known as the CMS-5000 Intracranial Fluids Monitor. The clearance includes a broad indication for use as an aid in assessing fluid volume differences between the cerebral hemispheres in patients undergoing neurologic assessment. The company says it is continuing clinical studies to further validate the device for identifying specific brain pathologies including stroke, trauma, swelling and others.

The Visor detects changes and distribution of cerebral fluids using its proprietary technology called Volumetric Impedance Phase-shift Spectroscopy. “Many neurologic conditions create a difference in fluid volumes between the brain's right and left hemispheres,” the company says. the device detects that fluid asymmetry as a change in the ratio of bioimpedance measurements on each of the two sides.
