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 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: A reverse retropulsion device can include a lithotripter, a collection passage, and an energy directing device. The lithotripter can be configured to deliver energy to tissue located at a tissue forming region. The collection passage can be positionable at or near the body lumen. The energy directing device can be positionable near the lithotripter and the collection passage. The energy directing device can be configured to propel the tissue toward the collection passage.

Abstract: A lithotripsy system can include a lithotripsy device and controller circuitry. The device for acoustic calculi fracture can include an acoustic treatment probe for providing acoustic energy along the probe to treat one or more calculi and an evacuation pathway extending at least partially via the prob, for removing at least a portion of the one or more calculi via the evacuation pathway. The controller circuitry, coupled to the lithotripsy device, can be configured to receive an indication of clogging of the evacuation pathway and at least one of initiate or adjust a anti-clogging mode for changing at least one characteristic of evacuation via the evacuation pathway in response to the received indication of clogging.

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: A multiple-modality ablation probe can include a tube configured to transmit mechanical modality energy from a first end to an obstruction in contact with a second end. A first optical transmission media can extend along the tube to transmit laser modality energy from a laser energy source to the obstruction. A connector assembly can be mechanically coupled with the first end of the tube and with the first end of the first optical transmission media. The connector assembly can be configured for user-attachment and detachment of the tube and the first optical transmission media with a mechanical energy source coupling and a laser energy source coupling, respectively.
