(b)(4).Device evaluated by mfr: the device was returned for evaluation.Device analysis observed guidewire detachment due to rotational wear in the middle of the device at 200.4cm from the proximal section.The distal section was returned with the distal tip damaged, unraveled and the detached from the distal tip end.Also the guidewire has kinks in the middle of the device and near to the broken section.The overall length and od of the distal tip were not measured due to the device condition while the rest of the od were within specification.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).

Same case as mdr id: 2134265-2016-02965.Reportable based on device analysis completed on 01mar2016.It was reported that a guidewire kink occurred.The target lesion was located in the non calcified coronary artery.A 330cm rotawire¿ and a rotalink burr were selected to treat the target lesion.During the procedure, the physician attempted to advance the burr to the wire; however, it was noted that the burr was unable to advance.The physician removed the device from the patient's body and noted that the rotawire was kinked.The procedure was completed with another of the same rotawire.No patient complications were reported and the patient's condition was good.However, device analysis revealed the rotawire was detached.
