(b)(4).Device returned condition was noted as: visible dents on surfaces of the gripper indicating previous effective use; abrasion visible on 3.0mm holes of handle and pivot plate which were elongated; threads damaged; and handle showed signs of wear by noted dents and scuffs.Review of device history records review found no anomalies.Guide wire grippers were dimensionally analyzed and met print specification, including hardness testing.Due to damage on the teeth, the gripper was noted to be unable to lock at fully stretched condition.This device is used for treatment.The damage on the locking teeth may have contributed to the gripping condition.Probable cause of elongation of the hole feature is likely wear due to normal use and teeth damage might be due to wear and tear or excessive force applied on locking nut but this cannot be confirmed with available information.The gripper has a potential field age of approximately 1.5 years with an unknown number of uses.Device has reached the end of its useful life.This mdr was identified during an internal retrospective review to meet reporting requirements and therefore is being filed retrospectively.
