Qn#: (b)(4).The customer provided one video for analysis.The video shows a damaged guidewire in a plastic bag.The customer returned one guide wire for evaluation.The catheter was not returned.The guide wire was unraveled and showed evidence of use.Visual examination revealed the guide wire was unraveled towards the distal end and had multiple kinks in the guide wire body.The distal j-bend core wire was misshapen but intact.Microscopic examination of the guide wire confirmed the core wire was broken towards the distal end with some core wire still attached to the weld.The weld was present at the end of the coil wire.The distal and proximal core wire tips were tapered and pinched at the points of separation.Both welds appeared full and spherical.Visual inspection of the catheter could not be performed as the catheter was not returned.The major kinks in the guide wire body were measured at 268mm, 448mm, and 540mm from the proximal tip.The proximal end of the broken core wire measured 579mm in length, and the distal end of the broken core wi re measured 24mm in length.The total length of the core wire was 603mm which is within the specification of 596-604mm per guide wire product drawing; therefore, no pieces of the core wire appear to be missing.The outside diameter of the guide wire measured 0.796mm which is within the specification of 0.788-0.826 mm per guide wire product drawing.Functional testing could not be performed due to the nature of the damage of the guide wire.A manual tug test confirmed that both welds were intact.A device history record review was performed on the guide wire and catheter no relevant manufacturing issues were identified.The instructions for use (ifu) provided with this product describes suggested techniques to minimize the likelihood of guide wire damage during use.Describes suggested techniques to minimize the likelihood of guide wire damage during use.The instructions caution that withdrawing the guide wire against the needle bevel or use of excessive force during removal could damage or break the wire.The report that the guide wire unraveled was confirmed through examination of the returned sample.The core wire was broken towards the distal end.The guide wire met all dimensional requirements during investigation testing.No manufacturing defects were found during this investigation.Arrow guide wires of this size are designed and manufactured to withstand a tensile force of 2.75 pounds force.The selected insertion site and patient anatomy may present a tortuous path that could contribute to the possibility of guide wire kinking.Guide wire breakage may occur if a force greater than the design specification is applied during removal.Based on these circumstances, unintentional use error likely contributed to this event, however, the probable cause of guide wire and catheter resistance could not be determined based upon the information provided and without the catheter being returned for evaluation.Teleflex will continue to monitor and trend for reports of this nature.
