Abstract: A single-use or reusable cap or an objective head to a scope can be used for integrating a laser fiber within the objective head but outside a working channel of the scope. The endoscope maintains an attached or embedded permanent laser fiber to ablate particulates that are suctioned into the endoscope assembly via a suction conduit. With such integration, there is no need to manipulate the laser fiber into a working channel; rather, a practitioner, e.g., physician, can move the medical device, including the laser fiber, as an entire unit into the patient toward the target stone and allow for suction of the stone through a working channel without blocking of the working channel by the laser fiber.

Abstract: Systems, devices, and methods for identifying a target in vivo are disclosed. A target identification system for use in electrosurgery includes a probe, an optical splitter, and a spectroscopy system. The probe includes an optical pathway to pass a first optical signal to an anatomical target and at least a portion of a second optical signal from the anatomical target. The optical splitter includes a first port to direct the first optical signal to the optical pathway and to receive the at least a portion of the second optical signal from the optical pathway, a second port to receive the first optical signal, and a parabolic reflector to redirect the portion of the second optical signal. The spectroscopy system can identify a characteristic of the anatomical target based on the redirected at least a portion of the second optical signal.

Abstract: A composition of a biological sample, such as tissue of a patient, can be estimated during an ablation procedure. A composition detector system can include a probe, an illumination source, and a spectrometer. A distal end of a probe can convey mechanical, acoustical, or ultrasonic energy to the tissue to ablate the tissue. The probe can extend through a working channel of a viewing scope. An illumination source can illuminate a portion of the tissue at the distal end of the probe or as the portion is being evacuated and collected for disposal. The illumination can generate response illumination from the portion of the tissue. The spectrometer can receive the response illumination, analyze the response illumination, and provide an estimate of the composition of the portion of tissue.

Abstract: An endoscope can comprise a proximal section, an insertion section extending longitudinally from the proximal section and comprising an elongate tubular body disposed along an insertion section longitudinal axis and a lumen extending through the elongate tubular body, and a distal section extending from the insertion section and comprising an elevator portion comprising an elevator configured to position and orient one or more endotherapy tools extending from the lumen, and a camera module comprising an illumination unit and an imaging unit. The camera module can be positioned longitudinally spaced apart from the elevator portion in an in-line configuration, such that the insertion tube longitudinal axis passes through the elevator portion and the camera module. The camera module can be user-detachable from the elevator portion. The camera module can be cleaned and sanitized for reuse and the insertion section can be disposable.

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 and methods for controlling an energy output setting of a lithotripsy device during a lithotripsy procedure are provided. The system includes a laser or other lithotripsy device configured for facilitating the lithotripsy procedure, an irrigation system configured for supplying an irrigant such as saline to a surgical site, and a temperature sensor configured to provide temperature data associated with the irrigant. The system can modulate the energy output setting of the lithotripsy device based on an estimated temperature that is determined based at least in part on the temperature data and one or more other factors such as a current energy output setting or a flow rate of the irrigant.

Abstract: Techniques for identifying composition of an anatomical target using a series of different colored light sources are provided. In an example, a method can include emitting light from multiple illumination sources, receiving an illumination response from an anatomical target at an optical sensor, providing an image representative of the anatomical target, and providing spectral intensity information of the illumination response in addition to the image. Each illumination source can emit light having a range of frequencies centered about a different frequency than each other illumination source.
