The device history record could not be reviewed because the lot number was not provided.The complaint sample was not returned for evaluation even though the complainant stated that a sample would be returned.If the sample is returned, it will be evaluated and the report will be updated.The (b)(4) introducer set uses a (b)(4) mandrel wire.From the event statement, it was noted that the doctor encountered some sort of resistance and pulled with more additional force than normal.The wire frayed and a piece broke off inside the patient.The ifu states warning withdrawal, pullback, or manipulation of the guidewire when resistance is met may cause guidewire damage, breakage, or embolization.In precautions at no time should the introducer or guidewire be advanced or withdrawn when resistance is met without determining the cause by fluoroscopic examination or suitable imaging method.It is probable that inadvertently using more than normal force during the resistance encountered caused the breakage of the wire.
