The reported customized tracheostomy tube was returned for investigation.The sample was received without its original packaging.During investigation, two potential lots were found for the returned device, ss002128 and ss00217.A device history review was performed on the two possible lots, no manufacturing non-conformities were found.Additionally, based upon a review of the device history files, it was found that the cuff functioned properly prior to shipment.During functional testing, the device cuff was inflated with 12cc of air; however, the cuff did not inflate.Upon examination, it was observed that a section of the adhesive on the distal tip was missing in an area where there should be a smooth bead of adhesive around the entire circumference of the shaft tip.The defect observed in the bond between the cuff band and the shaft at the distal tip of the shaft resulted in a leak.Investigation was unable to determine the root cause of the missing adhesive; however, no evidence was found to suggest a manufacturing defect.Mfr# clarification: new registration number 3012307300 (b)(4) has been received, however, this initial mdr was filed under the prior registration number 2183502 (b)(4).
