Reportable based on device analysis completed on (b)(4) 2015.It was reported that a wire kink occurred.The circumferential target lesion was located in the moderately tortuous and severely calcified right coronary artery (rca).A rotawire¿ and wireclip¿ torquer was used for advancing.The rotawire was delivered through an unspecified microcatheter, then the rotablator was also delivered.However, resistance was encountered upon delivery of the rotablator.The wire was then suspected to be kinked.The procedure was completed with another of the same device.No patient complications were reported and the patient's status was good.However, device analysis revealed body fracture.

(b)(4).Age at time of event: 18 years or older.Device evaluated by manufacturer: the device was returned for analysis.Visual inspection was performed and observed that the body was fractured at 328.1cm approximately from the proximal end.Moreover, the distal end including the spring tip approximately 1.9cm was not returned.All the outer diameter measurements are within the specifications.The manufacturing batch record review confirmed that the device met all material, assembly and performance specifications.The most probable root cause is operational context as device performance was limited due to anatomical procedural factors.(b)(4).
