Qn# (b)(4).The customer returned one, unopened arterial cath set for analysis.Visual analysis revealed the packaging had major folds and creases towards both the distal and proximal ends with two major folds observed overlapping the catheter and guide wire assembly.The protective tubing surrounding the guide wire was also kinked.The lidstock clearly states, "do not bend." the damage observed is consistent with defects related to storage and shipping.It is likely both the catheter and guide wire were kinked as a result of the folds in the packaging.The package was opened to analyze the contents within.The guide wire was removed from within the catheter and a total of four kinks were observed on the guide wire.Microscopic examination confirmed the damage and revealed that the distal and proximal welds of the guide wire were secure and intact.The kinks on the guide wire measured 39 mm, 51 mm, 71 mm, and 100 mm from the proximal tip.The guide wire length measured 349 mm, which is within the specification limits of 345-355 mm per the guide wire product drawing.The guide wire outer diameter measured 0.526 mm, which is within the specification limits of 0.508-0.533 mm per the guide wire product drawing.The guide wire was advanced through the returned catheter, and it was able to pass with little to no resistance.Performed per instructions for use (ifu) statement, "thread tip of catheter over guidewire.Precaution: allow sufficient guidewire length to remain exposed at hub end of catheter to maintain firm grip on guidewire.Grasping near skin, advance catheter into vessel." a manual tug test confirmed that the distal and proximal welds were intact.A device history record review was performed, and no relevant findings were identified.The provided with this kit warns the user , "do not use if package is damaged".The lidstock was reviewed as part of this complaint investigation.The words "do not bend" are clearly visible on the front of the lidstock.An engineering change order was implemented in april 2017 to update the product labeling to clearly inform the customer to not bend the product and is intended to reduce the potential for product damage.The customer report of a kinked guide wire was confirmed through complaint investigation of the returned sample.Four kinks were observed on the guide wire body.The returned packaging had multiple creases from being folded at the distal and proximal ends likely resulting in the damage observed on the protective tubing, catheter, and the guide wire within.The guide wire met all relevant dimensional and functional requirements, and a device history record review was performed with no relevant findings.The packaging clearly states, "do not bend." based on the customer description and the sample received, storage and shipping caused or contributed to this event.Teleflex will continue to monitor and trend for reports of this nature.
