Device evaluation: the device was returned for investigation.One decontaminated sample (b)(4) 8mm deht blu suctionaid sub-assy was returned for investigation without its original packaging.Under visual inspection we noticed tear in cuff.During manufacturing process the devices are 100% inflation tested, which includes inflating each device cuff and leaving for a 12 hour period.Reductions in pressure over this time are considered a failure and the device would be rejected.The inflation test was repeated on the received sample.It was found that it is not even possible to inflate cuff as it leaks so badly.History of internal ncrs showed that there was raised internal nonconformity report ncr1826 due to cuff tear which was found after inflation test.Corrective actions have been taken including initiation of quality alert, training of whole production during production town hall meeting, replacement of gauges and equipment with sharp edges by blunt versions, warning in manufacturing procedure and establishing better organization on affected workplace.No trend of confirmed complaints in relation with this issue was identified, cuff tear prior use is reported rarely, by implementation of actions from ncr1826 we reduced likelihood of such failure.The customer stated problem was duplicated.The cause of the reported problem was traced to the manufacturing process.A review of the device history records shows there were no observations recorded during manufacture to suggest an issue of this nature would occur with this lot of product.
