Cook Vacuum Pump for IVF – risk of electric shock or burn to operator

Manufactured by Cook Medical – risk of electric shock or burn, and failure of the device to operate during IVF procedures because of non-compliant mains wiring.


  • Identify the affected devices as stated in device details and, in the manufacturer’s, Field Safety Notice (FSN).
  • Ensure that all users receive the manufacturer’s FSN and that they understand the problem.
  • Ensure a residual current device (RCD), which is marked stating its compliance with BS 7071, is fitted to the mains electricity supply to mitigate the risk of a hazardous situation. RCDs are also known as a ground fault circuit interrupter (GFCI), ground fault interrupter (GFI), or an appliance leakage current interrupter (ALCI).
  • If you do not have access to an RCD (or equivalent) do not use the vacuum pump until the mains wiring for the unit has been replaced by the manufacturer.
  • If an adverse event occurs relating to this issue please report this to the MHRA via Yellow Card or the relevant devolved administrations (Scotland, Wales and Northern Ireland).
