The present invention relates to Fiber Feedback (FFB) technology, and provides a method and system for estimating distance between a fiber end and a target. The method includes illuminating, by a Light Emitting, Transmitting and Detecting (LETD) system, the target with laser light of different wavelengths having low and high-water absorption coefficients, using different laser light sources, as well as receiving a returned signal corresponding to the incident laser light of different wavelengths, and detecting the returned signal to measure intensity values of the returned signal of a specific wavelength. Using the measured intensity values, a processing unit may estimate distance between the fiber end and the target. The present invention enables accurate estimation of distance between a fiber end and a target, and also provides a robust distance estimation technique which is compatible with different types of targets.

A surgical instrument including a housing, a shaft, and end effector, and a sensor. The shaft extends distally from the housing. The end effector is disposed at a distal end of the shaft and includes first and second jaw members that are moveable relative between first and second configurations. The first and second jaw members are spaced relative to one another in the first configuration and are closer to one another for approximating tissue in the second configuration. A gap distance is defined between the first and second jaw members. The sensor is positioned within the housing and operable to determine the size of the gap distance. The first and second jaw members configured to be electrical activated to treat tissue between the first and second jaw members when the size of the gap distance is within an acceptable range.

The present disclosure provides, according to some embodiments, methods and systems for selectively reducing, blocking or inhibiting at least part of the neural activity in an organ of a subject. In preferred embodiments, the method and system are used for selectively blocking at least part of the neural activity in a duodenum of a subject in need thereof. According to some embodiments, the selective blocking occurs through use of laser radiation. According to some embodiments, the selective blocking comprises causing damage to at least part of sensory nerves located within a target area while maintaining functional activity of tissue surrounding the sensory nerves. According to some embodiments, the sensory nerves include neurons configured to transmit signals triggered by food passing through the duodenum, such as, but not limited to, neurohormonal signals.
