Event Description

During a peripheral atherectomy procedure using a csi orbital atherectomy device (oad), a device issue occurred.The target lesion was 75% stenosed and located in the anterior tibial artery.During treatment of the lesion with the oad, the device emitted a strange noise and seemed to stop spinning.The device was turned off, moved backward, and restarted, however the same issue occurred.Fluid was noted to be leaking from the front of the device, and blood was noted to flow back through the catheter.The nose cone of the device was noted to be loose.When the device was removed, it was found to be stuck on the guide wire.The oad and wire were removed together, the lesion was re-wired and the procedure was completed with balloon angioplasty.The patient was discharged the day following the procedure and no adverse consequences were reported.

Manufacturer Narrative

The reported oad was returned for analysis with the guide wire utilized during the procedure.The guide wire spring tip was noted to be damaged but intact.No other damage was observed to the oad or guide wire.The oad driveshaft was found to be fused to the guide wire core as a result of adhered biological material.The cause of the adhered biological mateirial is unknown.Analysis of the oad found that the nose cone glue plug had not been secured with adhesive during the manufacturing process, resulting in the glue plug detaching from the nose cone assembly.At the conclusion of the device analysis investigation, the report that the device became stuck on the guide wire and the nose cone being loose were confirmed.The reports of unusual noise and the device ceasing to spin were unable to be 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).
