(b)(4).The customer returned multiple components from a cvc kit.The guide wire will be analyzed as part of this complaint investigation.Signs-of-use in the form of biological material was observed on the guide wire tubing.Visual analysis revealed that the guide wire contained three distinct kinks across the guide wire body.This resulted in the distal j-bend to be slightly misshapen.Microscopic examination confirmed the kink and revealed that the distal and proximal welds were secure and intact.The kinks in the guide wire measured 28mm, 31mm, and 370mm respectively from the distal end.The guide wire total length measured 603mm, which is within the specification limits of 596mm-604mm per the guide wire graphic.The guide wire outer diameter measured.805mm, which is within the specification limits of.788mm-.826mm per the guide wire graphic.The guide wire was passed through the returned catheter.Minor resistance was observed at the kinks, but the guide wire was able to pass completely through the catheter.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, "although the incidence of spring-wire guide failure is extremely low, practitioner should be aware of the potential for breakage if undue force is applied to the wire".The ifu also states, "do not withdraw spring-wire guide against needle bevel to minimize the risk of possible severing or damaging of spring-wire guide".The report of a kinked guide wire was confirmed through complaint investigation.Visual analysis revealed three distinct kinks across 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.Based on the customer report and the sample received, unintentional user error likely caused or contributed to this event.Teleflex will continue to monitor and trend for reports of this nature.
