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 product sample was received at the site for analysis and investigation; it consisted of two incomplete kits of the product palindrome which came inside a generic plastic bag.Visual inspection was performed and the components did not show signs of use.As part of the evaluation, the guide wires were passed through the introducer needle and resulted in the guide wire passing easily through the introducer needle.Dimensional testing was performed for the guide wires and the introducer needle and the measurements were within specification.This component has defined characteristics as part of its design which makes it flexible for gentle manipulation during use.The sample evaluation and dimensional tests revealed that no defective conditions were identified in the guide wires or needle.There is no evidence to link this failure with manufacturing activities.Based on the available information the needle could be blocked by a biological particle during the needle insertion and the most possible cause for this issue is related to an inappropriate manipulation by the user.It must be noted that in-process controls (such as personnel training, incoming quality acceptance testing for raw material, 100% in process visual inspection and visual acceptance sampling) are in place to prevent nonconforming product.This complaint will be recorded for tracking and trending purposes.
