  • Patent number: 11980350
    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.

  • Publication number: 20240023796
    Abstract: Systems, devices, and methods for delivering laser energy directed toward target tissue using a spectroscopic feedback. An exemplary laser feedback control system comprises a feedback analyzer to receive a signal from a target tissue using a spectroscopic sensor, and a laser controller to determine whether the received signal generally equals a first preset. If the received signal meets the first preset, the laser controller can send a control signal to a laser system to change from a first state to a second state of the first laser system. The laser system can deliver laser energy via an optical fiber towards the target tissue.

  • Publication number: 20230363777
    Abstract: The medical system includes a basket treatment tool a processor. The processor determines, one or more of: a first determination, based on a transmissive image including the biliary duct, of whether a size of a gallstone allows the basket treatment tool to remove the gallstone from the papillary orifice, or a second determination, based on a resistance when the basket treatment tool is pulled, of whether the resistance allows the basket treatment tool to remove the gallstone from the papillary orifice; and controls the basket treatment tool to remove the gallstone from the papillary orifice when one or more of the first determination or the second determination determines that the gallstone is removable from the papillary orifice.

  • Publication number: 20210045811
    Abstract: A medical laser apparatus, including: an energy guide; a first energy source configured to generate energy for treating a target tissue through the energy guide; a second energy source configured to emit first and second aiming beams to a target tissue through the energy guide, the second aiming beam having at least one characteristic different from the first aiming beam; and a controller comprising hardware, the controller being configured to: receive a signal indicating an illumination mode from at least two illumination modes used by an endoscope to illuminate the target tissue; and control the second energy source to output the first or second aiming beam based on the indicated illumination mode.

  • Publication number: 20210038307
    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.
