Age at time of event: 18 years or older.(b)(4).The device was returned for analysis.Returned product consisted of the rotablator rotalink plus device.The advancer unit and burr unit were received together with the wireclip torquer in the wireclip torquer docking port.The advancer, coil, sheath, handshake connections, burr, and annulus were microscopically and visually examined.Microscopic examination of the device revealed that the annulus was damaged and not rounded which is consistent with damage seen with the use of a rotawire.The wireclip torquer was removed from the docking port and was clipped back in with no issues.Functional testing was performed by connecting the advancer to the rotablator control console system.The rotablator system was able to reach optimum speed with no issues and the burr catheter spun/moved with no issues and the brake worked properly.Product analysis confirmed that there was no issue with the device.The investigation conclusion is not confirmed - returned as there was no evidence of either the alleged issue(s) or any defect which could have contributed to the event.(b)(4).
