Abstract: Systems, devices, and methods for automatic control of surgical site temperature during an endoscopic procedure are disclosed. An exemplary endoscopic surgical system comprises an endoscopic surgical device controllably coupled to a medical instrument to deliver energy to a surgical site during a procedure, an imaging sensor to generate images or video frames of at least a portion of the surgical site during the procedure, and a controller circuit to analyze the generated images or video frames to determine whether a degree of heat built up in a first target at the surgical site exceeds a predetermined threshold. Based on such determination, the controller circuit can determine whether to adjust at least one operating parameter associated with the endoscopic surgical system to achieve or maintain a treatment effect of a different second target at the surgical site while avoid damaging the first target during the procedure.

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: An elevator for an endoscope comprises a first end secured to the endoscope, a second end movable by an actuator, a flexible portion positioned between the first and second ends that is rotatable when the second end is moved by the actuator, and a guide portion extending between the flexible portion and the second end to receive an endotherapy instrument extending from the endoscope, the guide portion comprising a chute to guide the endotherapy instrument leaving the endoscope. A method of forming an elevator comprises forming from a planar sheet of material an elongate body comprising a length between first and second ends, a width, and a thickness, forming a guide body in the elongate body, bending the elongate body such that first and second lengths of the elongate body oppose each other to form an interior space, and bending the guide body to extend into the interior space.

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: Systems, devices, and methods for identifying a target during an endoscopic procedure are disclosed. An endoscopic target identification system includes an endoscope having an endoscopic illumination source, an optical fiber insertable through a working channel of the endoscope and coupled to a non-endoscopic illumination source different from the endoscopic illumination source, and a controller. The controller can send a control signal to the non-endoscopic illumination source to emit a diagnostic beam through the optical fiber when the at least one endoscopic illumination source changes from a first mode to a second mode. The second mode has a lower amount of illumination than the first mode. The controller can determine a composition of a target based on the diagnostic beam incident on the target and light from the diagnostic beam being reflected from the target.

Abstract: A laser can be controlled based on different tissue compositions, such as in real time. After a first time period, a first composition of a in vivo target site can be identified. Based on the first composition, a plurality of lasers can be controlled to emit light at a first wavelength where controlling includes activating a first combination of the plurality of lasers. After a second time period, a second composition of the in vivo target site different from the first composition can be identified. Based on the second composition, a plurality of lasers can be controlled to emit light at a second wavelength, such as can include activating a second combination of the plurality of lasers. The first combination of the plurality of lasers can be different from the second combination of the plurality of lasers.
