Qn#(b)(4).The customer returned the product lidstock, an arrow raulerson syringe (ars), a spring-wire guide (swg) assembly and an introducer needle for evaluation.The guide wire was returned with the proximal end inside the swg tubing and the distal tip advanced through an ars and an introducer needle cannula.Visual examination of the swg revealed multiple offset coils on the j-bend tip and a slight bend in the swg body.The ars and introducer needle contained no defects or anomalies.The bend in the swg body was located approximately 195 mm from the distal weld.The offset coils on the j-bend tip were located approximately 7-13 mm from the distal weld.The length and outer diameter of the swg were measured and were found to be within specification.The guide wire was able to be advanced through the returned syringe and introducer needle with minimal resistance, despite the offset coils and bend found during visual ins pection.A manual tug test confirmed that both the proximal and distal welds were intact.A device history record review was performed on the introducer needle, guide wire, and ars and no relevant manufacturing issues were identified.(con't) other remarks: the ifu provided with this kit warns the user, "do not withdraw spring-wire guide against needle bevel to minimize the risk of possible severing or damaging of spring-wire guide." the report that the guide wire kinked during use was confirmed through examination of the returned sample.The guide wire distal j-bend tip contained offset coils, and the swg body contained a bend.The returned guide wire, introducer needle and ars all met all relevant functional/dimensional requirements and a device history record review did not identify any manufacturing related issues.In addition, the returned guide wire was able to pass through the ars and introducer needle with minimal resistance.Based on the condition of the returned guide wire and the report that the damage was observed during use, it was determined that operational context caused or contributed to this event.Teleflex will continue to monitor and trend for reports of this nature.
