A device for detecting stenosis comprising disposable components to ensure function and sanitary conditions, said device having a disposable sensing pad, a disposable piezo assembly, and a disposable sensing pod; wherein the entire device can be disposed of after a predetermined number of uses to ensure accuracy of results and of sanitary conditions.

Disposable sensing elements comprising a piezoelectric unit

A method for measuring sound from vortices in the carotid artery comprising: a first and second quality control provisions, wherein the quality control compares detected sounds to pre-determined sounds, and upon confirmation of the quality control procedures, detecting sounds generated by the heart and sounds from vortices in the carotid artery for at least 30 seconds. A method for determining stenosis of the carotid artery in a human patient consisting of a first step of placing a sensing device comprising an array and three sensing elements onto the patient, wherein a first sensing element is placed near the heart and the two remaining sensing elements are placed adjacent to the carotid arteries; the sensing elements then measure sounds from each of the three sensing elements, resulting in sound from three channels. The sound is measured in analog and modified to digital format and then each of the three channels are analyzed before a power spectral density analysis is performed. The power spectral density graph reveals peaks that are not due to noise, that are then analyzed to provide for a calculation of percent stenosis or complete occlusion of the carotid artery.

Method for detecting blockage in a fluid flow vessel

A method for measuring sound from vortices in the carotid artery comprising: first and second quality control provisions, wherein the quality control compares detected sounds to pre-determined sounds, and upon confirmation of the quality control procedures, detecting sounds generated by the heart and sounds from vortices in the carotid artery for at least 30 seconds.

Non-invasive method for measuring sound frequencies created by vortices in a carotid artery

A method for determining proper placement of a sensor pod on a patient comprising: performing a first quality control procedure on a detection device, wherein said detection device comprises a base unit, at least two sensor pods, a computer system implementing appropriate software, and a display; wherein the first quality control procedure generates a tone from a speaker embedded within said base unit and wherein each of said sensor pods measures and compares the measured sound to a predetermined measurement in real-time; wherein a sensor pod is determined to have met quality control if said sound is within 10% of the predicted measurements; performing a second quality control procedure on said sensor pods, wherein said sensor pods measure sounds on a patient; wherein the system, once engage, detects sounds from the sensor pods and compares the detected sounds in real-time to a predicted sound based on the fluid flow vessel; and wherein said method provides for an audio or visual alarm when said sensor pod is not detecting the predicted sounds, indicating an improper location for the sensor pod.
