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: A reverse retropulsion device can include a lithotripter, a collection passage, and an energy directing device. The lithotripter can be configured to deliver energy to tissue located at a tissue forming region. The collection passage can be positionable at or near the body lumen. The energy directing device can be positionable near the lithotripter and the collection passage. The energy directing device can be configured to propel the tissue toward the collection passage.

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: 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.

Abstract: A multifiber assembly and methods of using the same in an endoscopic procedure for transmitting illumination light to, and a response signal reflected from, a target is disclosed. An exemplary device comprises a proximal end, and distal end, and a transition section between the proximal and distal ends. The proximal end includes a first connector to be connected to a light source and a second connector configured to be connected to a spectrometer. The distal end includes a shaft including at least two first optical fibers to transmit light and at least one second optical fiber to transmit a spectroscopic signal. The transition section can couple the first connector to the at least two first optical fibers, and to couple the second connector to the at least one second optical fiber.

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: 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: 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.
