Samples were not received for the investigation.A device history record review could not be performed because a lot number was not received with the complaint.As part of our manufacturing process, all device history records are reviewed and approved by quality, prior to release of product.Because a sample was not returned, we were unable to perform a follow up investigation to include functional and visual evaluations to confirm the defect and root cause analysis.However, the following potential failures were identified: failed inspections or verifications per procedure, incorrect or damaged mold used during tube extrusion (causing stress at exit site due to improper bend), error in catheter placement, excessive force when inserting the catheter (not following instructions for use).With the available information it is not possible to determine a true root cause for this issue.Should the sample be returned in the future, this complaint will be re-opened for further investigation.It must be noted that in-process controls (such as personnel training, incoming quality acceptance testing for raw material, in process visual inspection and visual acceptance sampling) are in place to prevent nonconforming product from leaving the manufacturing operations.As per (b)(4), manufacturing performs 100% visual inspection at the final stage of production, which would identify this issue in the catheter assembly.This complaint will be used for tracking and trending purposes.
