Frequently Asked Questions

  • What do the LED indicator lights' colors mean?
  • What size vessels can be coagulated with the Sonicision™ system?
    The Sonicision™ cordless ultrasonic dissection device can be used to coagulate isolated vessels up to 5 mm in diameter.
  • What action should be taken to remedy a red device indicator light upon assembly?
    • Remove and re-attach battery pack
    • Re-torque generator
    • Replace battery pack
    • Replace generator
    • Replace cordless ultrasonic dissector
  • How do I know when the battery and generator have reached 100 uses?
    Both components have internal counters and display different lights when they have reached maximum use life - 100 uses. A flashing red LED indicator on the battery charger and a flashing purple LED indicator on the generator indicate end of useful life for the components. The battery and generator were designed to provide optimal performance throughout their lifespan.
  • How long does it take to recharge a battery?
    A depleted battery typically takes approximately two hours to fully recharge.
  • How long does a battery last during a case?
    The actual amount of capacity for energy activations depends on many factors including; idle duration, shelf life, and use profile, however our research indicates that one fully-charged Sonicision™ battery should satisfy the majority of procedures when ultrasonic energy is typically used. It is always wise to have a second battery on-hand and available for all cases.
  • What would cause the battery's safety valve to release pressure? Is the battery rendered useless at this point?
    • A scenario that would possibly cause the safety valve to release pressure is placing the battery in the autoclave.
    • If the safety valve has been released the battery is no longer usable.
  • How long can a battery sit on a shelf before needing a recharge?
    To maintain optimal performance the battery pack should be used as soon as possible after completing charge. However, the battery should be submitted for recharging and sterilization after 30 days of continuous time on the shelf without use
  • What happens if the battery and generator are autoclaved?
    The materials used to house the battery and generator are not designed to withstand the high temperatures experienced in an autoclave system. Exposing the battery and generator to autoclave temperatures will cause the external material to deform, damage the battery cells, and render the components unusable.
  • If the battery is colder than 50°F, how long will it take to charge?
    Batteries that are colder than 50°F will charge at roughly 10% of the normal charge rate until that battery temperature exceeds 50°F at which time it will return to the normal charging rate.
  • How long after a battery is initially purchased and received should it receive its first charge?
    Battery packs are shipped from Medtronic to the customer with a low charge and in a "deep sleep" state. To avoid damage and ensure the battery pack remains functional, the battery pack should be charged upon initial receipt by the customer.
  • What is the typical time that should be anticipated for the battery and generator components to be processed through the central sterile department?
    Based on the processes outlined in our user's guide and feedback from central processing managers, we anticipate the cleaning, charging and sterilization steps will take several hours to complete. In hospitals with on-site central sterile capabilities products may be available for reuse as soon as these steps are completed. For hospitals that contract their central sterile services offsite this may lead to a turn-around time of up to several days. You are encouraged to confirm the specifics of this process with each Sonicision target hospital.
  • How long does it take to clean, sterilize, and charge a Sonicision™ system?
    The average time frame is about four hours.
  • Why does the device "time out" during activation of energy?
    The device will "time out" (stop delivery of energy to tissue) after approximately 20 seconds of continuous activation. This safety feature provides protection against prolonged unintentional activations. When a "time out" occurs during intended use the operator should simply release and re-engage the dual-mode energy activation button.
  • Approximately how many activations remain once the yellow LED indicator light is displayed?
    The yellow LED indicator signals a battery has less than 20% remaining capacity. It is recommended to replace the battery as soon as possible.
  • How long can a battery stay alive once connected to the dissector?
    The Sonicision™ dissector draws minimal power from the battery when connected but no activated. The battery's life is primarily determined by number of activations.
