(b)(4).Device evaluated by manufacturer: the device was returned for analysis.Visual inspection of the device revealed that the body was bent.The device body was fractured 133cm proximal of the distal tip.The broken end of the device body had excessive wear due to rotational wear.The proximal end of the rotawire was unable to be inserted into the rotablator plus device for the related complaint device, as the annulus was damaged.Dimensional inspection of the overall length could not be performed due to the fractured body.Outer diameters of distal tip, middle, and proximal section of the device were within specification.The manufacturing batch record review confirmed that the device met all material, assembly and performance specifications.The investigation conclusion is user / use error as there was an act or omission of an act that resulted in a different medical device response than intended by the manufacturer or expected by the user: "exercise care in handling of the guidewire during a procedure to reduce the possibility of accidental breakage, bending, kinking, or coil separation.Resulting guidewire fractures might require additional percutaneous intervention or surgery.Do not allow the individual burr run time to exceed 30 seconds as this may lead to wire fracture/tip separation that may result in perforation, dissection, embolism, myocardial infarction and in rare cases, death.The rotawire guidewire has an expected functional life of 5 minutes which is a total of individual burr run times.Do not allow the burr to remain in one location while rotating at high speeds, as this may lead to wear of the guidewire." (b)(4).

Same case as mdr id: 2134265-2018-01690.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.
