The oad and guide wire were received for analysis.The oad driveshaft was cut and was stretched and deformed at the cut.The distal driveshaft, including the crown, was not returned.No additional damage was observed on the oad.The device data logs revealed numerous motor stall that occurred.The stall events did not recur during device analysis.The oad was tested, spun on all speeds, and functioned as intended.At the conclusion of the device analysis, the report of the oad becoming stuck in the vessel was unable to be conclusively confirmed.It was possible that the stalls that occurred in the device log could be attributed to the device being stuck in the vessel; however, the root cause of the stall events could not be determined.The device history record for this oad lot number has been reviewed.No issues or discrepancies were noted during this review that would have contributed to the reported event.The device met material, assembly, and quality control requirements.3004742232-2020-00225 is related to the guide wire used during this procedure.Csi id# (b)(4).

A stealth peripheral orbital atherectomy device (oad) was selected for treatment of a lesion in the proximal anterior tibial (at) artery.The lesion was long and 100% occluded.The oad became stuck and attempts were performed to loosen it, including cutting the oad.However, the attempts were unsuccessful.The patient was transferred to surgery to remove the oad.All portions of the oad were removed during surgery, and as of (b)(6) 2020, the patient status post-surgery was fine.
