Additional Manufacturer Narrative
The device was returned to olympus for inspection.The device evaluation found the c-cover was burned, and the air/water tube and air/water cylinder had white foreign materials.Based on the results of the investigation, the probable cause of the burned c-cover was a high-energy treatment device was used without ensuring a sufficient distance from the tip.The root cause of the white foreign material could not be identified.Based on the results of the investigation, it is likely the following led to the malfunction: the use of products that contain silicone can cause deposits of white foreign material.Silicone is for example included in simethicone, a defoaming agent, lubricants and so on.If the customer used them, there was risk that foreign material remained in the channel even if the reprocessing was conducted in accordance with the instructions for use (ifu).Simethicone and petroleum/oil/silicone-based lubricants are non-water soluble and thus not recommended for use by olympus.The event can be detected/prevented by following the instructions for use which state: ¿nothing other than sterile water should be used for air/water feeding.No additives should be put into the sterile water.Non-sterile water may cause patient cross-contamination and/or infection.¿ should additional relevant information become available, a supplemental report will be submitted.Olympus will continue to monitor the field performance of this device.This mdr was submitted during the system outage from july 22, 2026, to july 27, 2026, which may result in a delay of receipt of all of the acknowledgements.
