A device history record (dhr) review revealed no discrepancies that may have contributed to a complaint of this failure mode.All quality assurance testing performed during manufacturing was acceptable.The quality assurance review of the visual, physical and dimensional evaluation results indicated that the product met specification requirements.In addition, all dhrs are reviewed for accuracy prior to product release.The physical sample involved in the reported incident was not returned for evaluation, however four photos were provided by the customer.Visual evaluation of these photos was performed; the first three pictures showed a guide wire inside a generic plastic bag, in these photos it could be observed that the guide wire was stretched and bent on different points of its surface, the last photo was observed with an original label of the (b)(6) product; this image was not clear enough, the description and lot number of the product could not be identified.With the available evidence, it was not possible to determine if the guide wire presented a defective condition that may be related to the reported condition.According to the lot history record review, the referred lot does not reveal any deviation of the current procedure that might have contributed to the defective reported condition.The guide wire is covered by a plastic component which has the purpose of assuring the integrity of the stainless steel.This component has defined characteristics as part of its design which makes it flexible for gentle manipulation during use.The photo evaluation revealed that the guide wire was stretched and it was heavily manipulated, which implies that there were attempts to introduce it.According to the event description the defect occurred after customer manipulation during the initial insertion, the defect was not identified and the guide wire functioned as intended the moment when it was introduced in the patient.There is no evidence to link this failure with manufacturing activities.Based on the available information the guide wire was damaged during the catheter insertion and the most possible cause for this issue is related to excessive force during the insertion.It must be noted that in-process controls (such as personnel training, incoming quality acceptance testing for (b)(4), 100% in process visual inspection and visual acceptance sampling) are in place to prevent nonconforming product from leaving the manufacturing operations.This complaint will be used for tracking and trending purposes.
