Manufacturer Narrative

The reported oad was received at csi for analysis. A visual examination identified adhered biological material on the driveshaft distal to the crown. The adhered material prevented a guide wire from passing through the area and the driveshaft was cut proximal to the biological material. The guide wire was able to pass through the remaining device without encountering resistance. The oad was powered on and off multiple times with no issues observed. At the conclusion of the device analysis investigation, the report that the device became stuck in the vessel and a vessel perforation occurred could not be confirmed through analysis. It is possible that the adhered material observed on the driveshaft may have been related to the stuck in vessel and perforation events, however this could not be confirmed. Examination did not reveal any damage that would have contributed to the accumulation. The morphology and exact root cause of the accumulation is unknown. 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. Csi id: (b)(4).

Event Description

Orbital atherectomy was selected for treatment of the left anterior tibial (at) and tibioperoneal trunk (tpt) arteries. The proximal at was 70% stenosed and the mid to distal segment was a straight chronic total occlusion (cto). The tpt was 90% stenosed, with the peroneal artery providing collaterals to the posterior tibial artery. Some difficulty was encountered crossing the at lesions and the cto, but there were no unusual turns or bends of the wire and imaging revealed that the microcatheter was intraluminal. Proximal to distal treatment to the at with the diamondback peripheral orbital atherectomy device (oad) was performed. Treatment was continued to the cto on low speed, with some overlapping treatment. Medium speed was selected, the oad sounded as though it had stalled, and the device had become stuck in the vessel. The oad was pulled back through the lesion, and during removal wire access was lost. The oad and wire were both removed and imaging of the cto revealed a vessel perforation. Attempts to re-cross the cto with a catheter and non-csi wire were unsuccessful. Percutaneous transluminal angioplasty was performed to the proximal portion of the at and tpt, following which a residual perforation remained. The leg was wrapped with an elastic bandage to provide external compression. Following the procedure, the patient remained hemodynamically stable and the patient's lower extremity remained warm with a pulse and no signs of swelling.
