Other text: this remediation mdr was generated under protocol (b)(4), as a result of warning letter cms#(b)(4).No problem or issues were identified during the device history record review.A sample was received for evaluation.A decontaminated sample was received in plastic bag without its original packaging.During manufacturing process, the devices are 100 percent 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 after 12 hours cuff is significantly deflated.Source of leak was identified under water.Root cause was found to be there was air leaking from connection of inflation line and pilot balloon.The instruction for use states each cuff shall be also tested by customer prior use.Due to fact that cuff leak was observed after placement it is the most probable that reported failure occurred during tracheostomy procedure or during use., corrected data: d1, d2 (common device name) and d4.
