Qn#(b)(4).The customer returned one opened hemodialysis catheterization set included 2-l ctheter, swg, dilator, ars/needle, and lidstock for evaluation.Visual examination of the guide wire revealed on small kink inside the distal j-bend.Both welds of the wire appeared full and spherical.No other defects or anomalies were observed on the returned components.The kink in the guide wire measured 8mm.The overall length of the guide wire measured 601mm which is within specification of 596-604mm per product drawing.The outer diameter of the guide wire measured 853mm which is within specification of.838-.877mm per product drawing.The overall length of the catheter body measured 168mm which is within specification of 157-177mm per product drawing.The returned guide wire passed through the returned catheter, the returned dilator and the returned ars attached to the returned introducer needle with minimal resistance.A manual tug test confirmed both welds were intact on the guide wire.A dhr review was completed with no relevant findings.The ifu provided with this kit describes suggested techniques to minimize the likelihood of guide wire damage during use.The ifu cautions that if resistance is encountered when attempting to remove the spring-wire guide after catheter placement, the spring-wire may be kinked about the tip of the catheter within the vessel which may result in undue force being applied resulting in spring-wire guide breakage.If resistance is encountered, withdraw the catheter relative to the spring-wire guide about 2-3 cm and attempt to remove the spring-wire guide.If resistance is again encountered, remove the spring-wire guide and catheter simultaneously.The report that the guide wire kinked during use was confirmed through examination of the returned sample.A small kink inside the distal j-bend was observed.The returned guide wire and catheter met all relevant dimensional requirements and a device history record review did not identify any manufacturing related issues.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.
