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 lever latching system comprising: a housing; a lever having a latch pin fixedly mounted to the lever, the lever being movably mounted to the housing so that the latch pin moves in an arc; and a latch plate movably mounted to the housing for linear movement with respect to the housing, the latch plate comprising a labyrinth for receiving the latch pin.

Abstract: A uterine manipulator including an elongate shaft having a distal portion configured to be inserted into a uterus through a lumen of a cervix, and a return electrode coupled to the elongate shaft. The return electrode is configured to be electrically coupled to an electrosurgical generator.

Abstract: An endoscopic medical apparatus can include an endoscope tip extender such as can be configured to extend longitudinally axially from a distal portion of an endoscope in a tapered arrangement. The tip extender can define a bore such as extending longitudinally axially within the tip extender. The tip extender can include a material that can be at least one of softer or more flexible than a material of the distal portion of the endoscope.

Abstract: A colpotomy device having a tissue treatment assembly for performing a hysterectomy is provided. The tissue treatment assembly comprises an elongated body defining a longitudinal axis and an end effector coupled to a distal portion of the elongated body. The end effector can be offset from and rotatable about the longitudinal axis. The tissue treatment assembly also has an axial first electrical contact coupled to the end effector, where the axial first electrical contact is affixed to and rotatable with the end effector. Moreover, the tissue treatment assembly includes a circumferential second electrical contact that can be arranged to contact the axial first electrical contact throughout a rotation of the end effector about the longitudinal axis.
