Abstract: Techniques for estimating composition of a biological sample during an ablation procedure are provided. In an example, a composition detector system can include a probe, an illumination source, and a spectrometer. In an example, the probe can extend through a working channel of a viewing scope and can convey mechanical, acoustical, or ultrasonic energy to tissue of a patient to ablate the tissue at a distal end of the probe. A portion of the tissue may be illuminated at the distal end of the probe or as the portion is being evacuated and collected for disposal by the illumination source. The illumination can generate response illumination that can be received by the spectrometer. The spectrometer can 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.
