(b)(4).Device evaluated by manufacturer: the device was returned for analysis.Returned product consisted of a rotablator rotalink plus device with the rotawire for the related complaint.Microscopic examination of the device revealed that the annulus was damaged, not rounded and flared.The annulus was blocked due to the damage.The damage to the annulus is consistent with damage caused by the rotating burr coming into contact with the guidewire during use.The rotawire used in the procedure was returned for product analysis, so functional testing was completed with this rotawire.Even though the rotawire was received fractured, it could still be used for functional testing by attempting to insert the proximal end of the wire into the annulus.The wire was not able to be inserted into the annulus due to the damage and it being blocked.The investigation conclusion is caused by other device as another device/drug/subsequent procedure caused the complaint event.(b)(4).

Same case as mdr id: 2134265-2018-02465.Reportable based on device analysis completed on 17-feb-2018.It was reported that the burr would not load onto the rotawire.A 1.25mm rotalink¿ plus and a rotawire¿ were selected for use in a coronarography room.During the procedure, it was noted that the rotaburr would not load onto the rotawire.No patient complications were reported.However, device analysis revealed that the rotawire was fractured.
