Manufacturer Narrative

Analysis of the reported device is in progress.A supplemental report will be submitted when the device analysis is completed.(b)(4).

Event Description

The stealth orbital atherectomy device (oad) sheath became stuck in the iliac bifurcation, and the driveshaft became stretched.The iliac bifurcation had a narrow diameter.Additional access was obtained on the opposite side to push the device back, and the oad was able to be removed.No fractures occurred, and the procedure time was extended by almost an hour.

Manufacturer Narrative

The device was received at csi for analysis.There was no crown or driveshaft damage or abnormality that appeared to have contributed to the device becoming stuck.Visual examination revealed multiple areas of damage to the driveshaft, sheath and guidewire that likely occurred during attempts to remove the stuck device.Further examination of the driveshaft revealed filar deformation.The driveshaft had been destructively cut with the wire engaged.The driveshaft damage was destructively removed to allow for functional testing, and the device functioned as intended.The distal end of the guide wire appeared to have been pulled to failure with the spring tip not having been returned.Scanning electron microscopy analysis revealed the fracture face to exhibit damage due to stretching and tensile forces.Per additional details reported to csi, this guide wire fracture occurred outside the patient.At the conclusion of the failure analysis investigation, the reported events were partially confirmed.Although the root cause of the stuck device is undetermined, the device damage appears to be the result of attempts at removing the stuck device from the introducer sheath.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).
