Abstract: The present disclosure describes a device and method for detecting distributed pressures along a medical device. The device includes an optical fiber that is helically wound around the flexible shaft of the medical device. Responsive to microbends caused by the application of a pressure to the optical fiber, attenuation occurs as light propagates down the optical fiber. The device detects the light attenuation and calculates the pressure exerted on the device. Accordingly, a physician can ensure pressure induced by the medical device does not surpass clinically safe levels.
