This device referenced in this report has not been returned to olympus keymed for evaluation.A leakage test was carried out and positive leak was confirmed from the biopsy channel.Further investigation found the leaking area to be located at the connection between the biopsy channel and the channel mount.Fluid ingress and severe corrosion were present internally within the control section.The biopsy channel was confirmed to be damaged and leaking and has resulted in fluid entry within the instrument control section.The fluid ingress has subsequently caused severe corrosion to the biopsy port and surrounding areas.Based on the above observations, the substance found to be leaking from the instrument channel is attributed to the fluid that has entered the instrument through the leak, has subsequently discolored through corrosion and mixing with internal lubricants, and then has leaked back out of the instrument.The manufacturing history was reviewed, with no irregularities related to this problem noted.The instrument was sold (b)(6) 2012 and has no repair history with olympus service.
