Prior to sending the perforator to the supplier for evaluation, the perforator including the cutting edges was evaluated under high magnification (40x).There were no obvious anomalies noted on the cutting edges.The edges did not appear to be rolled, gouged or distorted.The label was torn, therefore; the lot number could not be confirmed.Root cause for the reported problem (perforator was blunt) was not verified.All evaluation tests and inspections had acceptable results.The perforator met functional test method acceptance requirements; proper engagement and disengagement was achieved with every drilled hole, there was no erratic and poor cutting action.A review of the device history records was not confirmed.The lot number is unknown; a section of eto label with lot# is torn away, and the lot# was not reported by the affiliate.Trends will be monitored for this and similar complaints.At the present time this complaint is considered closed.
