  • Publication number: 20240123225
    Abstract: In some examples, a system includes processing circuitry configured to receive a first set of information, the first set of information comprising information of actual therapy delivered to a patient over a plurality of instances of therapy delivery. The processing circuitry may determine, based upon the first set of information, a therapy usage pattern. The processing circuitry may determine a modification to a programmed therapy schedule based on the therapy usage pattern. The processing circuitry may generate for output the modification to the programmed therapy schedule.

  • Patent number: 7237708
    Abstract: An apparatus and system are disclosed for indicating relative positions of elements in a surgical apparatus. The indicating elements can include electrical circuitry that provides means for activating visual, audible or tactile indicators, thereby alerting the user that an event has occured with respect to the instrument.

  • Patent number: 5792150
    Abstract: An apparatus is provided for applying surgical clips which includes provisions for applying a partially closed clip to ducts or shunts during a surgical procedure. The apparatus includes a ratchet mechanism for permitting incremental closure of a pair of jaw members. A slide member is associated with the ratchet mechanism to prevent a movable handle from opening during a closing stroke until the closing stroke is completed.

  • Patent number: 5755726
    Abstract: An apparatus is provided for applying surgical clips which includes provisions for applying a partially closed clip to ducts or shunts during a surgical procedure such as cholecystectomy procedures. The apparatus includes means for effecting a partial closing stroke of the handle mechanism to correspond to a partial closure of the jaw members, and permits a partial opening stroke to release the partially closed clip in the jaw mechanism. Other features of the invention include means for preventing over advancement of a clip to the jaw mechanism, means for cradling the clip as it is advanced from the clip supply to the jaw mechanism, means for preventing splaying of the jaws in the event of a clip-over-clip application, and a novel rotation collar. The instrument of the present invention provides the surgeon with visual, audible, and tactile indication of the positioning of the jaw members to effect the application of a partially closed clip.

  • Patent number: 5241289
    Abstract: An industrial rated molded case circuit breaker fitted with an exhaust arc gas manifold arranged over ventilation slots of the circuit breaker and disposed at a line end thereof to redirect the arc exhaust gases exiting the ventilation slots. The exhaust arc gas manifold is fixedly attached to the circuit breaker to prevent an electric fault from occurring between the different phases of a multi-phase electric power distribution system connected to the line end of the circuit breaker. An electric fault is further prevented between the exiting arc gases and the line terminals attached to the circuit breaker thereof.

  • Patent number: 5113312
    Abstract: A combination panelboard-switchboard housing accepts plug-on connection with a plurality of electric switch-circuit breaker modules. Circuit breakers can also be directly connected onto the bus bars in a plug-on connection with minor modification. The bus bars are "edge-mounted" such that the minor dimension of the bus bars is perpendicular to the bottom of the housing to receive the modules as well as the circuit breakers, per se. Electrical insulation shields are arranged over those bus bars that are not connected with the circuit breakers or modules to prevent inadvertent contact with the bus bars when energized. The tabs extending from the edge of the insulation shields are keyed to accommodate for the different widths of the modules when the insulation shields are flush-mounted against one side of the modules.
