Abstract: A method of identifying an illumination light source in a surgical system comprises steps of receiving a signal from a target after the target is illuminated by the illumination light source, performing spectroscopic analysis of the received signal, and based at least in part on the spectroscopic analysis, determining a characteristic of the illumination light source. A method of treating a target comprises receiving a signal from the target after the target is illuminated by an illumination light source, performing spectroscopic analysis of the received signal, based at least in part on the spectroscopic analysis, determining a first characteristic of the illumination light source and a second characteristic of the target, and based at least in part on the determined characteristics of the illumination light source and the target, operating a surgical system to treat the target.

Abstract: Systems, devices, and methods for delivering laser energy to a target in an endoscopic procedure are disclosed. An exemplary method comprises providing a first laser pulse train and a different second laser pulse train emitting from a distal end of an endoscope and incident on a target. The first laser pulse train has a first laser energy level, and the second laser pulse train has a second laser energy level higher than the first laser energy level. In an example, the first laser pulse train is used to form cracks on a surface of a calculi structure, and the second laser pulse train causes fragmentation of the calculi structure after the cracks are formed.

Abstract: Systems, devices, and methods for automatic control of laser treatment of target structure in a body of a subject based on acoustic feedback in response to delivery of laser energy to the target are disclosed. An exemplary laser energy delivery system comprises a laser system to direct laser energy at a body target, and a controller circuit to receive an acoustic signal in response to delivery of laser energy to the target, and to measure acoustic properties from the acoustic signal. The control circuit may generate control signals for controlling the laser system to adjust laser energy output, or for controlling an actuator to adjust a position of a laser fiber distal end relative to the target to achieve a desired therapeutic effect.

Abstract: Systems, devices, and methods for determining a distance between a distal end of an endoscope and a target during an endoscopic procedure are disclosed. A surgical laser feedback control system comprises a feedback analyzer and a controller. The feedback analyzer can receive at least two reflected signals from a target in response to electromagnetic radiation directed at the target. The at least two reflected signals correspond to respective different distances between a distal end of a device of a surgical laser system and the target. The feedback analyzer can determine a distance between the distal end of the device of the surgical laser system and the target based on the at least two reflected signals. The controller can generate a control signal to the surgical laser system to perform a predetermined operation based on the determined distance.

Abstract: A lithotripsy or other medical laser treatment system can include a lateral actuator to laterally displace a distal portion of a laser fiber, such as can be scanned or otherwise controlled to generate a spatial or spatiotemporal sub-targeting pattern without requiring laterally moving an endoscope carrying the laser fiber in a longitudinal passage such as a working channel. A targeted stone can be selectively weakened along the pattern, such as using lower energy pulses, before being fragmented, such as by a higher energy shock pulse.

Abstract: A probe of a target identification system can be extended via a first lumen of a viewing instrument, such as for illuminating an area beyond a distal end of the viewing instrument via an optical path of the viewing instrument. An optical response to the illumination of the area can be received via an optical path of the probe and can be split from other optical signals of the optical path. The optical response information can be used to identify characteristics of a target and to adjust parameters of a working instrument such as a working instrument contemporaneously using the probe.

Abstract: Systems, devices, and methods for identifying a target in a body using a spectroscopic feedback from the target are disclosed. An exemplary surgical feedback control system comprises a feedback analyzer configured to receive a reflected signal from a target in response to electromagnetic radiation directed at a target, and a controller in operative communication with the feedback analyzer. The controller can generate a control signal to a surgical system to perform a predetermined operation based upon the received reflected signal, including determining a composition of the target, or programming a laser setting to direct laser energy to the target.

Abstract: Various aspects of methods, systems, and use cases may be used to deploy a light source to a targeted organ location via a working channel of an endoscope, such as in a manner that leaves the working channel free for use by another instrument and that can avoid requiring an additional channel, beyond the working channel, for illumination of a target region.

Abstract: A method for determining a characteristic of material at a target is provided. A target is illuminated with a pulsed light source. A fluorescence signal from the target when the pulsed light source is an “off” state is then sensed. Based on analysis of the fluorescence signal, a characteristic of material at the target is identified. A device can then be controlled based on the identified characteristic of the material at the target.
