During inspection and testing, the probe was leaking ultrasonic medium due to perforation of the distal end sheath.The internal blade was found to work properly.There were no other damages observed such as kinks in the insertion section sheath.A review of the device history record found no deviations that could have caused or contributed to the reported issue.The device met all specifications at the time of shipment.Based on the results of the legal manufacturer's investigation, it is likely the image was not displayed due to ultrasonic medium leaking from the perforation at the distal end sheath.This likely resulted in air bubbles being mixed in and the ultrasonic picture not being created properly.After the air bubbles were removed, the ultrasonic picture was created properly.However, the root cause of the perforation could not be determined.The device's instruction manual provides the following cautions regarding proper usage of the device: "freeze the image whenever you are not actively viewing the ¿live¿ ultrasound image.When the equipment is in the freeze mode, no ultrasonic waves are emitted into the patient.Never push or pull the ultrasonic probe with excessive force or withdraw it into the bending section of the endoscope during probe rotation (real-time mode).Manipulate the ultrasonic probe slowly and carefully when the endoscope is sharply angled or the forceps elevator is raised.Forcefully pushing or pulling the ultrasonic probe may damage it.Do not attempt probe rotation while the ultrasonic probe is advanced abruptly.This could result in image flow and impeded or cause irregular rotation." olympus will continue to monitor field performance for this device.Investigation activities have been opened to manage the actions related to this report and any required mdr reporting.
