(b)(4).The customer returned one, opened sac arterial kit for analysis.No obvious signs of use were observed.The guide wire was returned assembled inside the catheter body.Visual analysis revealed two kinks on the catheter body.The guide wire was removed from the catheter and identical kinking was visible in the same locations on the guide wire surface.Microscopic examination confirmed the damage and revealed creasing on the guide wire tubing in the same location as the kinks.Further analysis also revealed that the distal and proximal welds were secure and intact.Based on the customer description, the damage observed is consistent with defects related to storage and shipping.The kinks on the guide wire measured 81mm and 113mm from the proximal weld.The guide wire length measured 349 mm, which is within the specification limits of 345-355 mm per guide wire product drawing.The guide wire outer diameter measured 0.510mm, which is within the specification limits of 0.508-0.533 mm per guide wire product drawing.The guide wire was functionally tested per the product instructions for use (ifu).The ifu provided with this kit instructs the user, "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." the guide wire was advanced through the returned catheter, and the undamaged portions were able to pass with no resistance.Resistance was encountered at the location of the kinking.A manual tug test confirmed that the distal and proximal welds were secure and intact.A device history record review was performed, and no relevant findings were identified.The ifu provided with the kit informs the user, "do not use if package is damaged".The lidstock label was reviewed and the words "do not bend" are clearly visible on the front of the lidstock.The customer report of a kinked guide wire was confirmed through complaint investigation of the returned sample.Two kinks were observed on the guide wire body.Despite this, the guide wire met all relevant dimensional and functional requirements, and a device history record review was performed with no relevant findings.The product lidstock for finished good sac-00820 clearly states, "do not bend." based on the customer description and the sample received, storage and shipping likely caused or contributed to this event.Teleflex will continue to monitor and trend for reports of this nature.
