    Abstract: The present disclosure is related to field of Fiber Feedback (FFB) technology, and provides a method and system for estimating the 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 disclosure enables accurate estimation of distance between a fiber end and the target. The present disclosure also provides a robust distance estimation technique which is compatible with different types of targets.

    Abstract: An optical fiber assembly includes an optical fiber with a bulbous portion at a first end of the optical fiber and an optical tip attachment surrounding a segment of the optical fiber proximate the bulbous portion. The optical tip attachment is configured to bend the segment of the optical fiber. The optical fiber tip attachment is configured to maintain an air gap between a cylindrical surface of the segment and an inner surface of the optical fiber tip attachment.

    Abstract: An optical fiber is disclosed which includes a protective outer jacket. The outer protective jacket is grooved to include one or more peripheral grooves formed into the jacket. In operation of a laser device, laser energy passes through the optical fiber to the distal tip of the optical fiber. As the distal tip erodes, the outer protective jacket also erodes in a controlled fashion such that portions of the outer jacket flake off as the fiber tip erodes to the position of the peripheral grooves formed in the outer jacket rather than in a random fashion.

    Abstract: A method of treating a mobile target tissue with a laser beam includes: providing a laser device for generating a laser beam and providing an optical fiber having a delivery end for guiding the laser beam to the target tissue; a controller causes the laser device to generate one or more laser pulses substantially along the same longitudinal axis. The controller causes the laser device to provide one or more laser pulses. The one or more pulses are selected to allow a vapor bubble formed by the one or more pulse to expand an amount sufficient to displace a substantial portion of the liquid medium from the space between the delivery end of the fiber and the target tissue. The one or more pulses are delivered to the target tissue through the vapor bubble after the vapor bubble has reached its maximum extent and has begun to collapse to reduce retropulsion of the mobile target tissue.

    Abstract: The disclosure provides a laser generator comprising several laser sources where each laser source is arranged to generate a series of laser pulses offset in time from the other series of laser pulses generated by the other laser sources. The offset series of pulses are combined to provide a composite series of laser pulses with a higher frequency than each of the series of pulses have individually. Further, the present disclosure provides that the pulses of the composite series of laser pulses are non-equidistant from each other.

    Abstract: The present disclosure provides a method and system for estimating the distance between an optical fiber end and a target. Treatments which use laser and optic fiber technology require high amounts of accuracy to ensure that the laser is aimed at the right target (stone, tissue, tumor etc.), to achieve the clinical objective of tissue ablation, coagulation, stone fragmentation, dusting and the like. Accordingly, it is important to know the distance between the target and end of the optical fiber (distal end) where the laser light is emitted, since the laser treatment parameters, such as energy, pulse width, laser power modulation, and/or repetition rate, are often determined based on the distance between the tip of the optical fiber to the target.
