Device evaluated by manufacturer: returned product consisted of the rotawire drive.The wire body, proximal end, and spring tip were visually and microscopically examined.Inspection of the device found that the spring tip was kinked and stretched.Tissue was identified on the wire body, but the exact nature of the tissue was unable to be determined.Functional testing consisted of using a test rotablator device, as the device used in the procedure was not returned.During functional testing, the returned rotawire was able to be inserted through the annulus of the burr and advanced through the advancer before being removed with no resistance or issues.Product analysis confirmed the reported interaction with vessel tissue, as tissue was identified on the device upon receipt.The reported vessel perforation could not be confirmed as clinical circumstances could not be replicated.
