(b)(4).A device history record (dhr) review was performed and there were no issues found that could relate to the reported complaint.The sample was returned for evaluation.A visual exam was performed and it was observed that the device was discolored.It was also noticed that there were some jagged edges (symptoms of cracks due to force) on the broken connector.The jagged edges where the connector split appeared to be ruptured by force.Based on the investigation performed, the reported complaint was confirmed.The type of detergent used, concentration of detergent, and autoclaving settings were unknown.A non-compatible detergent or concentrated detergent, or high autoclave temperature, could have adversely impacted the sturdiness of the connector when external forces were applied.In addition, if the lma proseal is sterilized together with lubricated medical instruments, the lubricant will accelerate deterioration of the connector.
