Manufacturer Narrative

(b)(4).The reported oad was received for analysis with the guide wire utilized during the procedure engaged in the device.A visual analysis found adhered biological material on the driveshaft and crown of the oad and on the guide wire spring tip.The morphology and root cause of the biological material is unknown.The guide wire was removed from the oad with significant resistance, and the wire was unable to be reloaded into the oad following removal.At the conclusion of the device analysis investigation, the report that the device became stuck on the guide wire was confirmed.Although the exact root cause of the issue was unable to be determined, it is hypothesized that the device became stuck on the guide wire due to the accumulated biological material.The root cause of the reported dissection was unable to be confirmed through analysis of the returned device.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 and the device met material, assembly, and quality control requirements prior to distribution.Csi id (b)(4).

Event Description

During a peripheral atherectomy procedure using a csi diamondback orbital atherectomy device (oad), a dissection occurred.The target lesions were located in the superficial femoral artery (sfa) and mid to distal posterior tibial (pt) artery.The lesion in the sfa was treated with the oad on low and medium speeds.The device was advanced to the pt and the second lesion was treated with one pass of the oad on low speed.When the device was retracted, it appeared to be stuck to the guide wire.Angiography was performed and no flow in the distal pt was noted.A catheter was inserted and three doses of nitroglycerin were administered.A prolonged balloon inflation with 2.5 and 3.0mm balloons was also performed.Angiography showed a flow limiting dissection in the pt.A stent was placed across a portion of the dissection and balloon angioplasty was again performed.Following this intervention the dissection was resolved and there was no limit to flow.The patient was in stable condition following the procedure and at a follow up one week post-procedure.
