(b)(4).The customer report of a kinked guide wire during use was confirmed through examination of the returned sample.The customer returned multiple components of a cvc kit, including one guide wire assembly and arrow raulerson syringe (ars), for analysis.Visual analysis of the guide wire revealed that it contained one kink towards the distal end.The returned guide wire met all relevant dimensional and functional requirements, and a device history record review did not identify any manufacturing related issues.The ifu provided with the kit informs the user, "do not use excessive force when introducing guidewire or tissue dilator as this can lead to vessel perforation, bleeding, or component damage".Based on the condition of the guide wire and the report that the damage was observed during use, unintentional use error caused or contributed to this event.Teleflex will continue to monitor and trend for reports of this nature.
