  • Patent number: 10405918
    Abstract: A surgical instrument includes a reusable component and a limited-use component releasably engagable with the reusable component. The limited-use component is configured for one or more uses and includes a clocking mechanism configured to count each engagement of the reusable component and the limited-use component to one another. The clocking mechanism is incrementally transitionable upon each successive count from one or more uses state, wherein the clocking mechanism permits both mechanical engagement and electrical coupling of the reusable component and the limited-use component to one another, to a spent state, wherein the clocking mechanism inhibits both mechanical engagement and electrical coupling of the limited-use component and the reusable component to one another.

  • Patent number: 10405921
    Abstract: Devices and methods for cooling microwave antennas are disclosed herein. The cooling systems can be used with various types of microwave antennas. One variation generally comprises a handle portion with an elongate outer jacket extending from the handle portion. A microwave antenna is positioned within the handle and outer jacket such that cooling fluid pumped into the handle comes into contact directly along a portion of the length, or a majority of the length, or the entire length of the antenna to allow for direct convective cooling. Other variations include cooling sheaths which form defined cooling channels around a portion of the antenna. Yet another variation includes passively-cooled systems which utilize expandable balloons to urge tissue away from the surface of the microwave antenna as well as cooling sheaths which are cooled through endothermic chemical reactions. Furthermore, the microwave antennas themselves can have cooling lumens integrated directly therethrough.
