Abstract: System and techniques for target identification system are described herein. In an example, a system can include a medical instrument for ablating a target and a mechanism for removing the ablated target from an anatomic site into an evacuation path. The evacuation path can include a measurement chamber. The system can also include a turbulence-generation system that can generate turbulence in the measurement chamber. The system can also include a target-identification system that can determine a characteristic of at least a portion of the ablated target in the measurement chamber.

Abstract: A clotting agent delivery system comprises a frame, a passageway extending along the frame, a discharge opening connected to the passageway, a clotting agent reservoir fluidly connected to the passageway to hold a clotting agent substance, a valve in the passageway to control flow of the substance through the passageway, and an actuator to allow propellent to flow into the passageway, wherein the valve and clotting agent reservoir cooperate to provide clotting agent substance to the discharge opening at constant pressure using the propellant. A method for delivering a clotting agent comprises inserting a delivery catheter into an anatomic area, coupling a clotting agent delivery system to the delivery catheter, the clotting agent delivery system having a reservoir of a clotting agent, operating a valve to release propellant for propelling the clotting agent, and conveying the propellant and the clotting agent to the delivery catheter at a constant pressure.

Abstract: An optical fiber having a distal end extending from a distal end of an endoscope can direct light to and from a target. An interferometer can receive first light pulses from a first frequency comb having a first repetition rate, form reference arm light pulses and measurement arm light pulses from the first light pulses, direct the measurement arm light pulses to and from the target via the optical fiber to form return light pulses, and interfere the return light pulses with the reference arm light pulses to form interferometer output pulses. A beamsplitter can interfere the interferometer output pulses with second light pulses from a second frequency comb having a second repetition rate to form system output pulses. Processor circuitry can determine, from a time duration between consecutive system output pulses, a spacing between the optical fiber and the target, and can take an action in response.

Abstract: A method of treating a calculi mass can include using an ultrasonic probe to produce acoustic energy and fragment the mass. The method can include varying the frequency at which fragmentation occurs to treat the mass with a resonant frequency. The ultrasonic probe can have a distal tip for contact with the mass, where the tip has a morphology for concentrating stress on the mass. The ultrasonic probe can have two or more ultrasonic horns to allow for higher voltage and power levels.

Abstract: A lithotripsy device can comprise a handpiece, a lithotripsy probe extending from the handpiece, an energization source configured to deliver an energy to a distal end of the lithotripsy probe, a suction passage extending from the distal end of the probe and through the handpiece, and a capture device comprising a container comprising a storage space, an entry port configured to couple to the handpiece at the suction passage, and an exit port, and a capture element connected to the container and configured to facilitate capture of stone fragments within the storage space. A method can comprise fragmenting stones with a lithotripsy device, drawing a vacuum through the lithotripsy device to pull stone fragments and waste fluid therethrough, pulling the vacuum through a stone capture device connected to the lithotripsy device, depositing stone fragments within the stone capture device using a capture element, and drawing the vacuum through the device.

Abstract: A laser tissue ablation system can include an optical fiber, with a distal end being extendible from an endoscope body of an endoscope. The optical fiber can deliver therapeutic laser light from the distal end of the optical fiber toward a target site, and receive return light into the distal end of the optical fiber. The laser tissue ablation system can include a sensor that can spectrally measure the return light. The laser tissue ablation system can include processor circuitry that can form a first determination, from the spectral measurement of the return light, whether flashing event light is present in the return light. The flashing event light can be generated when a flashing event occurs at the distal end of the optical fiber. The processor circuitry can generate, in response to the first determination, a flashing event data signal that indicates whether the flashing event has occurred.

Abstract: An endoscope comprises an elongate shaft extending along an axis from a proximal end portion to a distal end portion, a video imaging device located in the distal end portion, the video imaging device including a field of view, and an optical imaging systems, e.g., an optical coherence tomography (OCT) imaging system, configured to emit light outside of the field of view. A method of imaging anatomy using an endoscope comprises inserting the endoscope into anatomy of a patient, the endoscope comprising an elongate body with a central axis, obtaining imaging with a video imaging device that includes a field of view, emitting light from a distal end portion of the endoscope outside of the field of view, obtaining reflected light from the emitted light in the multiple radial directions, and generating optical images, e.g., optical coherence tomography imaging, of the anatomy from the reflected light.

Abstract: A laser lithotripsy guide system for guiding a laser fiber during a lithotripsy procedure may include a guide which may include a proximal end portion and a distal end portion. The guide may define a guide bore to receive a laser fiber therethrough. The guide may include at least one prong on the distal end portion. The guide system may also include a mounting assembly which may be securable to the laser fiber. The mounting assembly may be releasably insertable into the proximal end portion of the guide to releasably secure the mounting assembly to the guide.

Abstract: A medical device can include an elongate outer member and an elongate inner member in the elongate outer member. The elongate outer member defines a first lumen and includes a lateral suction port that is in fluid communication with the first lumen. The elongate inner member is rotatable relative to the elongate outer member and defines a second lumen. The second lumen includes an opening at a distal end of the elongate inner member to allow passage of fluid into the second lumen. The elongate inner member has a first lateral passage where the first lateral passage is rotatable into partial alignment with the lateral suction port to provide or control suction or other fluid communication between the lateral suction port and the second lumen. The medical device also has an electrode at a distal end of the inner member.
