(b)(4).Catalog# corrected to 004550003.The complaint description states that the green sheath covering the tip of the fiber optic tube on the laryngoscope blade slid off during intubation.To further evaluate, the sample was visually inspected for flaws.The blade arrived with a total of three breakages in the optic tube that caused the blade to disassemble into six parts.One of the breaks was near the green sheath, as described in the complaint.Rather than just the green sheath sliding off of the fiber optic tube, it was determined that a break on the fiber optic tube, approximately 6mm inside of the green sheath, caused a piece of the fiber optic tube to break off with the green sheath still covering it.The other two breaks were on the plastic base, however, these two breaks were not mentioned in the complaint description, and may or may not have occurred at the customer site.A comparison analysis was then performed to compare the complaint sample to an identical, brand new product to determine if there were any inconsistencies.No dimensional deviations were observed.Based on the investigation performed, the complaint was confirmed.It was determined that the complaint was a result of a break in the fiber optic tube within the green sheath.The blade could have been subjected to external forces beyond the design and essential performance requirements of the device, resulting in breaks in the fiber optic material.The two breaks at the plastic base were not mentioned in the complaint description.Therefore, it is suspected that these two breaks occurred during shipment of the complaint sample from the customer to teleflex (b)(4).The root cause of failure was likely damage that occurred during transportation from the manufacturer to the consumer.A conclusion code could not be found.
