(b)(4).The customer provided six images and a video showing a defective needle.The kit lidstock was also pictured.The pictures showed that the needle cannula was separated towards the needle hub.Analysis of the video shows the customer intentionally bending the needle cannula, which resulted in the separation to occur.The also customer returned one, opened cvc kit for analysis.No obvious signs of use were observed.Visual analysis revealed that the cannula on the returned introducer needle was separated towards the needle hub.Microscopic examination confirmed the separation and revealed that the cannula was slightly bent and oval at both ends of the separation.It cannot be determined if this location of the cannula was defective prior to the customer bending (per customer supplied video).It was also noted that the needle from the catheter over needle was bent.The point of separation on the needle cannula measured 5mm from the needle hub.The cannula outer diameter (in an area not affected by the damage) measured 0.0500", which is within the specification limits of 0.0495"-0.0505" per the cannula product drawing.The cannula inner diameter measured at the proximal end distal ends measured 0.042", which is within the specification limits of 0.041"-0.043" per the cannula product drawing.The returned guide wire was inserted through the defective cannula.Despite the damage, the guide wire was able to pass completely through both portions of the separation with minor resistance at the point of separation.Performed per ifu statement, "advance guidewire into arrow raulerson syringe approximately 10 cm until it passes through syringe valves or into introducer needle".The sample was sent for additional analysis by r & d.It was confirmed that the needle cannula passed the iso test criteria for flexing for the gauge size and wall thickness.There is no indicator that the needle has any type of manufacturing defect.A device history record review was performed based on the lot# of the sample received , and no relevant findings were identified.The ifu provided with the kit informs the user, "do not use if package is damaged".The report of a separated needle cannula was confirmed through complaint investigation.Visual examination revealed that the cannula was separated 5mm from the needle hub.The cannula appeared bent and oval at both ends of the separation which is consistent with a bend resulting in a break.Undamaged portions of the needle cannula met all relevant dimensional requirements, and a device history record review did not reveal any relevant findings to suggest a manufacturing related issue.Testing of the returned cannula performed by r & d confirmed that the needle cannula passed the iso test criteria for flexing for the gauge size and wall thickness.There is no indicator that the needle has any type of manufacturing defect.Based on the customer report, the sample received, analysis of the customer supplied video, and the analysis performed by r & d , the root cause cannot be determined as it is unknown of the needle cannula was damaged prior to the customer bending (per supplied video).Teleflex will continue to monitor and trend for reports of this nature.
