Title:
DETECTION OF STENOSIS IN A PROSTHESIS USING BREAK FREQUENCY
Document Type and Number:
WIPO Patent Application WO/2016/144812
Kind Code:
A8
Abstract:
A method for detecting a stenosis in a prosthesis includes providing a tubular prosthesis having a sensor coupled to the prosthesis and implanting the tubular prosthesis in a native fluid conduit. The sensor senses the stenosis and captures data that characterizes the stenosis. A spectral analysis of the data may then be performed in order to provide a frequency spectrum of the data. The frequency spectrum may be examined in order to identify a break frequency value in the frequency spectrum. The break frequency may then be translated into a percentage of stenosis in the tubular prosthesis.
