This mdr was generated under protocol (b)(4), as a result of warning letter (b)(4).A product sample was received for evaluation.Visual and functional testing were performed.No problems or issues were identified during this device history record review.One decontaminated unit pack was received for investigation.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 observed that it was not even possible to inflate cuff because it leaked badly.Cuff tear was visually confirmed.Due to fact that cuff leak was detected by customer during pre-use check it was the most probable this defect occurred during manufacturing or packaging of this device.Currently there was an non-conformance report (ncr) which is focused on reduction of possibility of cuff tear during manufacturing process.Replacement of gauges and equipment with sharp edges by blunt versions, warning in manufacturing procedure, quality alert, working with gloves and better organization on affected workplace.No trend of confirmed customer complaints in relation with this issue was identified.Occurrence of this defect was very rare.
