No device history records review was conducted since there was no reported lot # and ship history lot review was not performed since item # is unknown.The recent angiodynamics complaint report was reviewed for the insertion kits product family and the failure mode "guidewire fractured." no adverse trend was identified.As no sample was returned, no device evaluation is possible and the relationship between the device and the reported event is unable to be determined.While it is possible that the end user damaged the guidewire by pulling it back against a needle cannula, this cannot be confirmed.The directions for use (dfu) packaged with the mini stick max contains the following cautions: "do not withdraw guidewire through metal needles: guidewire may shear or unravel.If any obstruction is met, then do not attempt to remove guidewires over the needle or other metal instrument.Obstruction might occur during insertion and lead to tangled coiled part of the wire then difficulty to remove it through tip of the sheath." and "warnings: do not rotate the guidewire if significant resistance is felt".(b)(4).
