Abstract: A system for analyzing a reflected signal during a laser procedure can include a surgical scope. A first light source emitter can be configurable to emit a first signal having a first (e.g., a non-visible) spectrum. A second light source emitter can be configurable to emit a second signal having a second spectrum (e.g., a visible or infrared (IR) spectrum). Each of the first or the second light source emitters can be coupled to or included within the surgical scope. The system can include an optical sensor configurable to detect and analyze a third signal returned from the surface of an object in response to the emitted second signal. The returned third signal can be analyzed to determine whether a reflected absolute or relative intensity or an absolute or relative spectral signature meets at least one criterion, thereby triggering at least one of: warning a user or adjusting the first signal.

Abstract: A modular endoscope system comprises an exoskeleton, a camera unit couplable to the exoskeleton, a therapeutic unit couplable to the exoskeleton, a steering unit couplable to the exoskeleton, and a control unit couplable to the exoskeleton. A method for building a modular endoscope comprises determining camera and therapeutic capabilities of the endoscope, selecting an exoskeleton for the endoscope, attaching a camera unit and therapeutic unit, if such capabilities are determined, to the selected exoskeleton to satisfy the determined capabilities, and attaching a control unit to the exoskeleton to control any camera unit and therapeutic unit attached to the exoskeleton. A method of processing modular endoscope components for performing a surgical procedure comprises identifying a patient to receive a treatment, selecting components of the endoscope to perform the treatment, treating the patient with the endoscope, and deconstructing the components of the endoscope into reusable and disposable components.

Abstract: Systems and methods of in situ unclogging a working channel in a medical device during a procedure are disclosed. An exemplary unclogging system comprises a flow sensor to sense a flow rate through a working channel, and a control module to detect a channel state indicating a presence or absence of clogging based on the flow rate. In the presence of channel clogging, the control module can control one or more of an irrigation source or a suction source to provide respectively irrigation fluid or suction pressure to unclog the obstructed channel. The control module can adjust one or more of an irrigation flow rate or a suction flow rate through the working channel to maintain a desired pressure of the anatomical environment at the anatomical site, or to maintain a desired flow condition in the working channel, during the procedure.

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: Systems, devices, and methods for determining advancement of a surgical laser fiber in an endoscope and providing interlocking feedback for the surgical laser are disclosed. An exemplary method includes directing light from a distal end of an endoscope to a target, optically detecting an amount of the light reflected from the target, transmitting the optically detected amount of light through a laser fiber extending through a working channel of the endoscope, determining, based on the optically detected amount of light, a position of a distal end of the laser fiber relative to the distal end of the endoscope, and generating a control signal to the surgical laser system to adjust laser emission through the laser fiber.

Abstract: An endoscope can include an elongated endoscope body. An optical fiber can extend along the endoscope body. The optical fiber can direct therapeutic light and illumination light longitudinally along the optical fiber to a distal portion of the endoscope body. The therapeutic light and the illumination light can have different wavelengths. A wavelength-sensitive light separator, disposed at a distal portion of the optical fiber, can direct the illumination light to exit the optical fiber laterally through a lateral side of the optical fiber at the distal portion of the optical fiber and permit the therapeutic light to exit the optical fiber longitudinally through a distal end of the optical fiber. Examples of suitable wavelength-sensitive light separators can include one or more fiber Bragg gratings that can be obliquely angled, or a diffraction grating disposed on a lateral edge of a length of coreless fiber.

Abstract: Systems, devices, and methods for identifying different structure types with distinct composition in vivo and adjusting surgical laser output accordingly in a medical procedure are disclosed. An exemplary laser treatment system comprises a laser system configured to generate a laser beam for delivery to a target in a body, and a controller circuit configured to receive a signal reflected from the target in response to electromagnetic radiation produced by a light source, and generate one or more spectroscopic properties from the reflected signal. The controller circuit can identify the target as one of a plurality of structure types, such as tissue types or calculi types with respective compositions, using the one or more spectroscopic properties. The laser system can be controlled to operate in an operating mode based on the target identification.
