Manufacturing review: a manufacturing review was not required as this is the only complaint reported to date for this product and lot.Investigation summary: one 19cm equistream d/l catheter, two end caps, one 16.0fr peel-apart sheath, one vessel dilator, one 8fr & 12fr dilator, one introducer needle with a loaded guidewire in a guidewire hoop were returned for evaluation.Gross visual, microscopic visual, dimensional evaluation and functional testing were performed.The investigation is inconclusive for the reported guidewire advancement issue as the exact circumstances at the time of the reported event cannot be verified and the sample evaluation results indicating no difficulty under laboratory conditions are not by themselves sufficient to confirm that this event did not occur under clinical conditions.However, the investigation is confirmed for the reported guidewire damage, identified protrusion, uncoiling and fracture issues as the guidewire appeared to be uncoiling, distal to the introducer needle hub.Distal tip of the guidewire was noted to be bent.Furthermore, a flat core wire was noted to be protruding the uncoiled guidewire area and a complete break was noted on the distal end of the exposed flat core wire.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 could not be determined based upon the available information.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: 03/2023).
