Vittamed out of Carlisle, MA received European CE Mark approval for its non-invasive intracranial pressure meter and non-invasive cerebrovascular autoregulation monitor. The Vittamed 205 intracranial pressure monitor works by applying pressure to the tissue surrounding the eye using a special pressure cuff. A Doppler ultrasound transducer placed over the eye measures blood flow through the intracranial and extracranial parts of the ophthalmic artery. The blood flow through the extracranial segment changes as the pressure is applied to the eye, while the intracranial segment responds to the intracranial pressure. Applying pressure to the eye until the blood flow matches in the two segments of the ophthalmic artery results in equal pressure in both parts and a readout is produced by the system. This technique does not require calibration for each patient and the company claims there’s little to no discomfort during the procedure.
