The subject device was not returned to omsc for evaluation but was returned to (b)(4).Omsc reviewed the manufacturing history (dhr) of the subject device and confirmed no irregularity.The exact cause of the reported event could not be conclusively determined.However, based upon the information from (b)(4), there was the possibility that the reported phenomenon was attributed to occurring scratch at the distal end sheath due to some external force applied to the distal part by the user handling.Some external force might be swiftly insertion/withdrawing of the subject device from the endoscope with angulation and/or driving the probe.If additional information is received, this report will be supplemented.
