Manufacturer Narrative

The device was returned to omsc.Omsc investigated the device and confirmed the following: the reported phenomenon that a large part of the ultrasonic image was not displayed was not reproduced.The ultrasound image was displayed properly.There was a hole in the distal end of transparent sheath section, causing an ultrasonic propagation fluid leak.There were black spots on the ultrasonic transducer.Since there was a hole in the distal end of transparent sheath section, there is possibility that air bubbles have temporarily entered the ultrasonic transducer.Omsc concluded that the ultrasound image may have been abnormal because the ultrasound could not be transmitted normally due to the intrusion of air bubbles onto the ultrasonic transducer.The perforation of the distal end of transparent sheath section may have been caused by an external force applied to the distal end due to the following causes; with the ultrasonic probe driven, the ultrasonic probe was pushed and pulled vigorously from the endoscope.With the endoscope bent, the ultrasonic probe was pushed and pulled vigorously from the endoscope.There is possibility that an external force was applied to the distal end of transparent sheath section, which caused the ultrasonic transducer to be impacted and damaged, resulting in black spots on the ultrasonic transducer.However, omsc concluded that the ultrasonic transducer was not failed because the ultrasound image was displayed properly.Device history record (dhr) review indicates that the product was manufactured and tested in accordance with all applicable procedures and met all final product release criteria.If additional information becomes available, this report will be supplemented.
