(b)(4).Investigation - evaluation: a review of the complaint history, dimensional verification, device history record, instructions for use (ifu), trends, quality control and visual inspection of the returned device was conducted during the investigation.Review of device history record shows no nonconforming events which could contribute to this failure mode.It should be noted there were no other reported complaints for this lot number.The device is shipped with an instruction for use (ifu) that describes the intended use, specific items are addressed such as: " note: if resistance is noted tactilely or visually under fluoroscopy, determined the cause and take action necessary to relieve the resistance.Advancement and withdrawal of the wire guide should be performed slowly and carefully." this device is inspected for bends, kinks, adequate joint strength, correct outside dimension and other surface imperfections prior to release.There is no evidence to suggest the product was not made to specifications.One approach cto microwire wire guide was returned for investigation in a used and damaged condition.The device measured 300 cm in length with a kink located at 40.5 cm from the distal tip.Several (3) areas of missing coating measuring between 1 and 2 cm were identified at various points from the distal end; another 14 cm of coating is absent between 37.5 cm and 51.5 cm from the distal end.The coil was elongated for 8 mm at a point 3.2 cm from the distal end.A merit spinr torque device was obtained and functionally tested with an approach cto-6 wire guide.This torque device allows the user to rotate the wire guide several times with the activation of the trigger and opposite rotation with release of the trigger up to 2500 rpm.The reported failure mode of the coating coming off the wire guide was easily duplicated.Based on the information provided, examination of the returned device, functional testing with a competitor's product and the results of our investigation, it is plausible to suggest that user technique caused damage when the force exceeded design specification during a procedurally related event.We will continue to monitor for similar complaints.Per the quality engineering risk assessment no further action is required.
