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.

Internal secondary calculus fragmentation mechanism

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.

Real-time composition analysis techniques for ultrasonic ablation

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.

Lithotripsy system having a drill and lateral emitter

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.
