Detection of stenosis in a prosthesis using break frequency

A system for detecting a stenosis in a prosthesis in a patient's body, said system comprising:

• a tubular prosthesis;
• a sensor coupled to the tubular prosthesis, wherein the sensor is configured to detect and capture data related to a characteristic of the stenosis;
• and
• a transmitter operatively coupled with the sensor, the transmitter configured to transmit the data to a location external to the patient's body.

A method for detecting a stenosis in a prosthesis, said method comprising:

• providing a tubular prosthesis having a sensor coupled thereto;
• sensing the stenosis with the sensor and collecting data with the sensor, wherein the data characterizes the stenosis;
• performing a spectral analysis of the data to provide a frequency spectrum of the data;
• examining the frequency spectrum;
• identifying a break frequency value in the frequency spectrum;
• and
• translating the break frequency into a percentage of stenosis in the tubular prosthesis.
