  • Publication number: 20230389988
    Abstract: Techniques and a laser system for modulating laser pulses are provided.

  • Publication number: 20230355306
    Abstract: The present disclosure provides a method and system for estimating the temperature of a working environment. Treatments that use laser and optical fiber technology may cause an undesirable increase in the temperature of a working environment. To that end, a laser source to generate light beams sensitive to a change in temperature can be generated and the temperature determined based on a distance between a distal end of the optical fiber and a target and the generated temperature sensitive light beam.

  • Publication number: 20230314277
    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.

  • Publication number: 20230277244
    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.

  • Patent number: 11419679
    Abstract: Apparatus for the treatment of a target tissue with a laser beam in which the target tissue is immersed in a liquid medium within a body lumen. The laser device is configured to provide one or more laser pulses which are configured by a controller to have an energy sufficient to form one or more vapor bubbles in the liquid medium at the distal delivery end of the fiber. The one or more pulses are configured by the controller to: first, cause a vapor bubble to be formed distally of the distal end portion of the endoscope and around the distal delivery end of the optical fiber; second, cause a second bubble to be formed distally of the first bubble; and, third, inflate the second bubble as the first bubble has begun to collapse to expand an amount sufficient to displace a substantial portion of the liquid medium from the space between the distal delivery end of the fiber and the target tissue.

  • Patent number: 10263384
    Abstract: A single loop hardware-based system for producing laser pulses in a microsecond scale operational mode includes a GUI to enable a user to select the operational mode of the system; a laser source for producing one or more laser beam pulses, the laser source being a diode laser pump source module; a DSP which enables and disables a hardware-based FPGA. The FPGA controls the diode pump source module. When a user selects one or more microsecond scale laser sub-pulses on the GUI, the DSP transmits to the FPGA the sub-pulse energy level and the sub-pulse on-time selected by the user on the GUI. A photodetector operatively connected to the hardware-based system measures the power of the laser pulse beam that was transmitted to the photodetector and, in a feedback mode, transmits a feedback signal of that power measurement to the FPGA. The FPGA compares the power of the laser beam measured by the photodetector to the power of the laser beam selected by the user on the GUI.
