The CVR Carotid Stenotic Scan (CSS)

The Carotid Stenotic Scan (CSS) is a screening tool designed to detect and measure carotid arterial stenosis or occlusion for the purpose of identifying patients at risk for Ischemic Stroke.  The CSS provides a synergistic tool which complements other stroke screening technology such as Duplex Doppler ultrasound (DUS), magnetic resonance angiography (MRA), and computed tomography angiography (CTA). CVR’s screening device is non-emissive, non-invasive, does not require a certified technician, can be conducted in a few minutes, and has a per scan price point that is significantly advantageous as an initial screening tool when compared to the resource requirement associated with other technologies.

At what stage of development is the Carotid Stenotic Scan (CSS)?

Currently CVR is entering the Clinical phase of the development process.  The final market version of the CSS is being assembled and prepped for Pivotal Trials, which will then be submitted for FDA 510(k) clearance.

The Technology

CVR’s technology makes a connection between fluid flow and sub-sonic frequencies in order to determine the presence of arterial disease/blockage. The technology, in its present configuration, detects and analyzes the low frequency vibrations that radiate passively from the carotid arteries.  Blood flowing through the carotid arteries produces wave patterns which are shaped and altered by the presence of any irregularities on the inner walls of those arteries.  The wave patterns are captured and mathematically analyzed through CVR’s patented algorithms which generate an accurate percentage range of stenosis (including 100% stenosis, or complete occlusion). This analysis is then followed by immediate interpretation with details concerning the inner surface of the carotid arteries against which there is blood flow.
