  • Patent number: 11957370
    Abstract: Conventional vasectomy techniques suffer from a number of disadvantages and potential complications, including, for example, a substantial risk for the development of hematomas, swelling, and post-surgical pain, a potential for spontaneous regeneration and undesired resumption of fertility, a need for a highly skilled surgical professional, as well as a long recovery period, accompanied by severe limitations on post-surgical activity. The present invention overcomes the disadvantages and deficiencies of the prior art by providing vasectomy instruments, kits, and methods that allow for a rapid, reliable, less invasive male sterilization procedure that may be readily, reliably and successfully performed by minimally skilled personnel around the world in a variety of medical settings.

  • Patent number: 11896389
    Abstract: A paralysis monitoring system can be utilized during various medical procedures. Generally, the system is used during procedures involving anesthesia, when general paralysis is necessary, e.g., during surgery that requires cutting through or mobilizing muscle tissue. The paralysis monitoring system stimulates a nerve with low voltage signals and can provide for continuous monitoring and recording of the evoked muscle activity throughout and after a procedure. By monitoring a quantitative response of the muscle activity to nerve stimulation, an anesthesiologist may adjust subsequent doses of a paralytic agent to achieve a desired level of paralysis.

    Abstract: A method and device for controlling a treatment procedure includes a treatment tool, an energy source, and a controller. The controller controls the energy source such that in a first treatment phase, power fed into the material to be treated is controlled with an increasing course. An impedance detector determines the impedance course and/or the present impedance of the material to be treated, and recognizes the achievement of an impedance minimum. A timer is started upon recognition of an impedance minimum, and upon recognition of a further impedance minimum within the specific time interval, the timer is reset. If no new impedance minimum is detected within the specific time interval and the time interval expires, the controller switches the power control to constant power or to a power course with an altered gradient. Upon fulfilling a specific criterion, there is a switchover from power control to voltage control.

  • Patent number: 11497551
    Abstract: A tissue resecting device includes an outer sleeve having an axial bore extending along a longitudinal axis from a proximal end to a distal end and opening to an outer window near the distal end. An inner sleeve is rotatably received in the axial bore of the outer sleeve and has an axial channel adapted for communication with a negative pressure source. A distal housing is attached to a distal end of the inner sleeve and has an annular dielectric portion and a circumferentially adjacent annular metal portion having an inner window with circumferentially spaced-apart sharp cutting edges that opens to the axial channel. An active electrode is carried by the annular dielectric portion, and the inner window is circumferentially spaced-part from the active electrode so that the inner window and the active electrode rotate alternately into alignment with the outer window as the inner sleeve is rotated within the outer sleeve.
