(b)(4).The customer returned one single lumen arterial catheter for evaluation.The catheter body showed evidence of use in the form of dried blood.Visual and microscopic examination of the catheter distal tip revealed that the material on one side of the tip was deformed/damaged.The tip of the catheter was split, folded back, had ripples, and the cracks in the tip contained white discoloration, indicating stress.No other damage to the catheter was observed.The length of the entire catheter (including the hub) measured 5.25", which is within specification.The outer and inner diameter of the catheter body were also found to be within specification.The catheter tip could not accurately be measured due to the condition of the returned sample.A device history record review was performed on the catheter and no relevant manufacturing issues were identified.The instructions-for-use (ifu) provided with this kit describes suggested techniques for catheter insertion.It states to "firmly hold introducer needle hub in position and advance catheter forward, with a slight rotating motion, over spring-wire guide into vessel." the ifu also cautions the user to "not reinsert needle in to catheter to minimize risk of catheter damage." the reported complaint that the arterial catheter was split was confirmed during visual examination of the returned sample.The returned catheter tip was split, folded back, and contained white stress marks.A device history record review was performed with no relevant findings to suggest a manufacturing related issue.Based on the sample received, it was determined that operational context caused or contributed to this event.Teleflex will continue to monitor and trend for complaints of this nature.
