Manufacturer Narrative

Follow up report# 001 ref natus complaint# (b)(4).The customer was requested to return the defective unit.The customer responded that hospital policy regarding medical device adverse events is to investigate the device internally and then will decide whether it needs to be returned to the vendor.Case (b)(4) was set up to send a loaner unit (sn (b)(6)) and for the return of the defective unit.The customer emailed and ask for the reason for the failure.Service responded and said they do not know the root cause of the failure, and that the "the self-check verifies that the dab is correctly calibrated and ready to measure all three channels of eeg as well as the impedance for each of the p3, c3, p4 and c4 electrodes." they also requested for the customer to return the system after their internal investigation.There are no capa's related to this issue.This complaint does not identify a deficiency in the product design and therefore a capa is not required.Per qms-004442, complaint histories are reviewed routinely per quality system requirements and any complaint trends are assessed and documented as part of these reviews.A device history record review is not applicable because, prior to the reported issue the device was in service for 2 or more years and a manufacturing defect is very unlikely.Further investigation to be carried out.
