One used tracheostomy tube was returned for evaluation.Visual inspection found the device to be in a used condition.During functional testing, a syringe was used to inflate the device cuff with 7 cc of air; the cuff inflated and deflated very quickly.The cuff was then re-inflated with 7 cc of air and the entire device was submerged in water.Bubbles (indicating a leak) were observed escaping from the cuff of the device.The cuff was found to have cut/scratches in two different areas.A review of the device history records showed no non-conformities in the manufacturing process.Additionally, manufacturing performs a 100% inspection on all devices prior to being packaged.Therefore, the cuff is believed to have become damaged during device use.No evidence was found to suggest the reported event was caused from an intrinsic product problem.Additional information included in follow-up report: device return date (05/09/2016).Device evaluation completed (07/19/2016).
