(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.Visual analysis revealed two bends/kinks in the guide wire.Additionally, the distal j-bend appeared slightly misshapen.Microscopic examination confirmed the kinks and revealed that the distal and proximal welds were secure and intact.The kinks/bends in the guide wire measured 30mm and 242mm respectively from the distal weld.The guide wire total length measured 604mm, which is within the specification limits of 596mm-604mm per the guide wire graphic.The guide wire outer diameter measured.810mm, which is within the specification limits of.788mm-.826mm per the guide wire graphic.The guide wire was passed through the returned cvc catheter.Little to no resistance was observed.A manual tug test confirmed that the distal and proximal welds were secure and intact.A device history record review was performed with no relevant findings to suggest a manufacturing issue.The ifu provided with the kit informs the user, "wire guide breakage.If resistance is encountered, withdraw catheter relative to spring-wire guide about 2-3 cm and attempt to remove spring-wire guide.If resistance is again encountered remove spring-wire guide and catheter simultaneously".The report of a kinked guide wire was confirmed through complaint investigation.Visual analysis revealed two kinks/bends in the guide wire body.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.
