(b)(4).The customer returned one opened cvc kit with multiple components.Visual examination of the catheter revealed that the catheter tip was folded inward into the catheter body.Slight traces of biological material were observed on the catheter tip.No other defects or anomalies were observed.The catheter body from the juncture hub to the catheter tip measured 205.5mm, which is within the specification limits of 201.5-210.5mm per catheter product drawing.The inner and outer diameter of the catheter body were also within specification.A lab inventory long pin gage with a diameter of.032mm was inserted into the proximal end of the catheter.When the pin gage reached the catheter tip, resistance was felt.The pin gage was then used to push the folded portion of the tip out from the catheter body.After successfully completing this, the spring wire guide provided with the kit was inserted through distal end of the catheter.No resistance was felt.A device history record review was performed with no relevant findings.The ifu provided with the kit instructs the user "use vessel dilator to enlarge site as required" prior to the catheter insertion.The customer did not state whether the dilator was used.The ifu also warns the user "do not apply excessive force in removing guide wire or catheters.If withdrawal cannot be easily accomplished, a chest x-ray should be obtained, and further consultation requested." the customer complaint that the catheter tip was deformed was confirmed through complaint investigation.The returned catheter showed signs of use in the form of biological material on the catheter tip.A long pin gage was used to push the folded portion of the catheter tip out from the catheter body.After successfully completing this, the spring wire guide provided with the kit was passed through the distal tip of the catheter with no resistance.The catheter passed all relevant dimensional testing.A device history record review was performed with no relevant findings to suggest a manufacturing issue.Based on the received sample, it was determined that unintentional use error caused or contributed to this event.Teleflex will continue to monitor and trend for complaints of this nature.
