Manufacturing review: a complaint history review was performed.This is the second complaint reported for this lot number.A device history record review was performed and the lot met all release criteria.Investigation summary: one introducer needle attached to a guidewire.Gross visual, dimensional, microscopic visual and functional evaluations were performed.The investigation is confirmed for identified stretched and fracture issues, as the inner core wires showed the flat inner core wire to be fractured within the coils of the guidewire.The round inner core wire was also fractured within the coils of the guidewire.The outer coil of the guidewire was noted uncoiling just proximal to the hub of the introducer needle.However, the investigation is inconclusive for the reported guidewire failure to advance and difficult to remove issues, as the exact circumstances at the time of the reported event are unknown.Based on the measurements recorded during sample evaluation and applicable drawings, no measurements recorded could be confirmed to be out of tolerance.A definitive root cause for the reported failure could not be determined based upon the provided information.However, please note that the complaint report states that, they were trying to remove the wire while it was in the needle, and the instructions for use states, if the guidewire must be withdrawn while the needle is inserted, remove both the needle and the wire as a unit to prevent the needled from damaging or shearing the guidewire.The current situation was contrary to the instructions for use and is a possible cause of the event described.Labeling review: a review of product labeling documentation (e.G., procedural instructions, indications, warnings, precautions, cautions, possible complications, contraindications, nursing guide, and unit label) did not find any product labeling inadequacy.(expiry date: 06/2024).
