Abstract: A system to deliver energy to treat a mobile calculus, the system can include a drill and a lateral energy emitter. The drill can be configured to drill a recess into the mobile calculus or a passage through the mobile calculus. The lateral energy emitter can be configured to be advanced into the recess or the passage and to transmit the energy internal to the mobile calculus to fragment the mobile calculus. In some examples, the system can include a deployable capture portion to constrain a stone relative to the capture portion.

Abstract: An endoscope may include an expandable and collapsible working channel, a flexible endoscope body, and an optical sensor located at a distal tip of the endoscope body. The optical sensor can provide a distal field of view from the distal tip. In the collapsed configuration, the working channel can be collapsed such that a channel wall is in a first position relative to the endoscope body and the working channel defines a first cross-sectional area. In the expanded configuration, the channel wall is displaced relative to the first position and the working channel defines a second cross-sectional area that is larger than the first cross-sectional area.

Abstract: A laser lithotripsy system to deliver laser energy from one or more laser sources to a stone (e.g., mobile calculus), the system including a capture portion, a first laser node and a second laser node. The capture portion configured to be movable from a stored state to a deployed state. In the deployed state, the capture portion is configured to at least partially surround the stone. The first laser node and the second laser node are coupled to the capture portion and are configured to deliver the laser energy to the stone, and the first laser node is spaced apart from the second laser node.

Abstract: A multi-channel endoscope can include a control section and an insertion end. The endoscope can include a user control mechanism. The control section can include at least one working channel and a channel within the control section. The working channel can accommodate at least one medical instrument which can fracture a target object into fragments. A catheter, such as a fluidic catheter, can extend from and retract to an originating proximal position at the insertion end of the endoscope. A vacuum pressure source or an irrigation source can be coupled to a proximal end of the channel. The user control mechanism can control the position of the catheter with respect to the endoscope and can be used to operate the vacuum pressure source or irrigation source.

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: The present disclosure includes a calculi fracture device having an acoustic transducer for transferring acoustic energy via a primary fragmentation probe to fracture a calculi mass into calculi fragments, an evacuation tube connecting the probe to a pressure source, and a secondary fragmentation device located in an evacuation pathway extending along the fragmentation probe and the evacuation tube to further break up the calculi fragments to inhibit clogging at a more proximal location in the evacuation pathway. A method of inhibiting clogging of a calculi fracture device can include receiving, from a primary fragmentation device, fragments of a calculi mass along a passage of a evacuation pathway of the calculi fracture device and further breaking up the calculi fragments along the passage of the evacuation pathway at a location that is more proximal to a primary fragmentation location.
