Qn#(b)(4).Device evaluation: the reported complaint of the guide wire became kinked during insertion into the introducer needle could not be confirmed.The customer returned one guide wire and multiple other components in an opened kit.The introducer needle was not returned.Visual examination of the guide wire revealed one kinks at the distal end of the wire and the j- bend appeared opened.The kink was measured at 2.9 cm from the distal weld.Microscopic examination confirmed the kink and also confirmed that both welds were full and spherical.A manual tug test confirmed that both welds remain intact.The guide wire measured approximately 450 mm in the total length and exhibited an outside diameter (od) measured 0.793 mm.The returned guide wire was within specification for length and od per guide wire graphic (length: 450 - 458 mm and od: 0.788- 0.826mm).The other returned components, catheter, arrow raulerson syringe(ars) and dilator, all appeared used since dried blood was observed on both the outside and inside of these components.Functional testing was performed with the returned guide wire and each of these components separately.The guide wire passed through each component with no resistance.The instructions for use describe suggested techniques to minimize other remarks: the likelihood of guide wire damage during use.The device history record review was performed and did not reveal any manufacturing related issues.Since the introducer needle was not returned, the probable cause of this issue could not be determined.No further action will be taken.
