The reported oad was received for analysis.Adhered biological material was observed on the crown of the oad.Examination of the area of adhered material did not reveal any damage.The morphology and root cause of the biological material was unknown.No damage to the driveshaft or crown that could have contributed to the perforation was observed.A guide wire was passed through the area of adhered material with no resistance.The oad spun at all speeds and functioned as intended.The data logs of the oad showed that a motor stall occurred.At the conclusion of the device analysis, the reported event of a perforation was unable to be conclusively confirmed.The log report of an oad stall may have been related to the event of the oad slowing down, however, this was unable to be conclusively confirmed.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.(b)(4).

During a procedure with a stealth peripheral orbital atherectomy device (oad), a perforation occurred.The 100% occluded, heavily calcified lesion was located along the entire length of the posterior tibial artery (pt) and was treated on medium speed with the oad.The oad started to lose power and perforation occurred.The perforation was treated with balloon tamponade, and the procedure was delayed by greater than thirty (30) minutes.Pain medications were administered to the patient, a blood pressure cuff was applied.The patient was stable following the procedure.
