The CVR Carotid Stenotic Scan (CSS)

The Carotid Stenotic Scan (CSS) is a diagnostic tool designed to detect and measure carotid narrowing 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 groundbreaking 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)?

CVR has withdrawn its January 2019 De Novo submission for the CSS from the FDA and is expecting to resubmit at a later date.

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.

Features & Benefits

Game Changing Technology

The CSS is a truly unique device, unlike anything currently available. In a market that is starved for innovation, CVR is providing a device which is able to benefit Patients, Payers, and Providers.


The CSS is 100% non-invasive and does not require the use of harmful dyes.


Unlike other arterial health analysis modalities, the CSS does not use harmful radiation to obtain a result. The CVR device uses only sound wave analysis to detect the presence of arterial stenosis.

Cost Effective

With a target price point of less than $55,000, the CSS costs a fraction of the price of other devices used to determine arterial health. This price point, combined with an aggressive financing program, will allow for immediate ROI by the health care provider and rapid market penetration.


The CSS acts as a cost efficient gatekeeper for health care providers. Currently there is no viable way for doctors to manage arterial health without the use of expensive testing options. With the CSS in use, the clinician is able to prescribe further care for only those patients in true need, thus eliminating expensive and unnecessary testing.

Easy to Use

No specialized training is required to operate the CSS. Unlike other modalities which require costly human resource obligations, the CVR device will show results which accurately define the level of carotid narrowing.

Time Saving

With the ability to be placed in the Primary Care Providers office and eliminate unnecessary exams the CSS saves a significant amount of time and resources on the patient’s behalf.

Hassle Free

CVR Medical has made every effort to make the CSS both efficient and hassle free for all end users. With a simple log in screen, easy to order disposables, and wireless technologies eliminating troublesome wiring, the CSS will simplify an already complicated provider setting.
