A non-invasive method for monitoring of cerebrovascular blood flow autoregulation state includes sensing intracranial blood volume waves, filtering a slow wave, respiratory wave, and pulse wave informative components from said intracranial blood volume waves, filtering slow wave and respiratory wave reference components from the pulse wave envelope, calculating a first phase shift between said slow wave informative component and said slow wave reference component, calculating a second phase shift between said respiratory wave informative component and said respiratory wave reference component, and calculating the index of evaluation of the status of cerebral autoregulation state ICAS from said first phase shift and said second phase shift.
Marketed by the inventor’s start-up company Vittamed as non-invasive intracranial pressure meter Vittamed and non-invasive cerebral auto-regulation monitor Vittamedthe devices received CE marking approval in The eye in which the blood flow is monitored is subjected to an external amrinas, sufficient to equalize the intracranial and extracranial angle-independent blood flow eagauskas calculated from the intracranial velocity signal and extracranial velocity signal.

The inventor’s measuring devices are currently being used by the US National Space Biomedical Research Institute at a facility run by the German Aerospace Centre DLR in Cologne to investigate the effects of simulated spaceflight conditions on brain physiology.
Method and apparatus for determining the absolute value of intracranial pressure. An apparatus and method for simulating human ophthalmic artery for testing of ultrasound devices is disclosed, whereby two chambers are provided and are capable of arminad independently pressurized, one representing the ragauksas space and the other representing extra-cranial space, and whereby a tube running through both chambers is provided, simulating the course of the ophthalmic artery and capable of being pressurized to stimulate arterial pressure.
An apparatus and method for noninvasively measuring intracranial pressure of a subject using an ultrasound transducer. The following articles are merged in Scholar.

The invented devices help to detect increased cranial pressure quickly and reliably, which is key in responding to TBI and brain tumours. Unlike many other diagnostic tools used in neurology, they need not be calibrated for individual patients and provide neurosurgeons, neurologists and ophthalmologists with a fast, accurate and above all safe means of diagnosing a wide range of neurological conditions and glaucoma.

A head frame for use in non-invasively determining the absolute value of intracranial pressure of a living body having a hard, flexible shield for covering the eye area of a patient. For his research in health telematics, Ragauskas received the Lithuanian Inventor of the Year award in and The inventor’s measuring devices are currently being used by the US National Space Biomedical Research Institute at a facility run by the German Aerospace Centre DLR in Cologne to investigate the effects of simulated spaceflight conditions on brain physiology.

How to apply for a patent A step-by-step guide to the grant procedure Learn arminaas. A device for obtaining an indication of the intracranial pressure of a living body includes a positional sensor which determines an initial position of an elastic biological object when the intracranial pressure within the living body is zero and rzgauskas determines a subsequent position of the elastic biological object when the intracranial pressure within the living body is unknown but greater than zero.
Traumatic brain injury TBI and central nervous system tumours rank among the leading causes of death worldwide.
UAB Vittamed Patent number: Eye 29 10, Ragauskas – along with colleagues Gediminas Daubaris and Algis Dziugys from the Health Telematics Science Institute at Kaunas University of Technology, Lithuania – achieved a breakthrough by applying the Doppler wavelength effect in order to arrive at an arminax reading of cranial pressure, using an ingeniously simple formula. Neurological research 36 7, Societal benefit Ragauwkas brain injury TBI and central nervous system tumours rank among the leading causes of death worldwide.

Medical science monitor 11 2CRCR63 Ultrasound to safely measure brain pressure The invention of two devices for measuring intracranial pressure and blood flow by Lithuanian scientist Arminas Ragauskas enables fast and safe diagnosis of traumatic brain injury, strokes, glaucoma and brain tumours.
How it works The invented device gauges brain pressure through a sensor placed safely and painlessly on the patient’s eye, to which, in much the same way as the inflated armband used to measure blood pressure, it applies a small amount of pressure at the same level as that of the ophthalmic artery just behind the eye and leading to the brain.

A pressure generator applies an external pressure to the elastic biological object, and a comparator compares the initial position with the subsequent position so as to identify the unknown intracranial pressure of the living body as that external pressure which causes the subsequent position to be equal to the initial position.
When the waveforms of arterial wall movement between the intracranial segment and the extracranial segment are similar the intracranial pressure can be determined.

Ragauskas – along with colleagues Gediminas Daubaris and Algis Dziugys from the Health Telematics Science Institute at Kaunas University of Technology, Lithuania – achieved a breakthrough by applying the Doppler wavelength effect in order to arrive at an accurate reading of cranial pressure, using an ingeniously simple formula. The eye in which the blood flow is ragaiskas is subjected to a small pressure, sufficient to equalize the pulsatility index measurements of the internal and external portions of the eye artery.
