(b)(4)the customer returned an opened es-04701 set containing various components including a guide wire assembly for evaluation.None of the components showed any evidence of use.The guide wire was returned fully retracted within the advancer tube with the end cap secure.Visual examination of the guide wire did not reveal any defects or anomalies.The distal j-bend was undamaged and both welds were full and spherical.The overall length and outer diameter of the guide wire were measured and were found to be within specification.The guide wire was functionally tested by advancing it through the catheter, dilator, arrow raulerson syringe (ars) and introducer needle.The guide wire advanced through each of the components with minimal resistance.Manual tug test confirmed both the distal and proximal welds are intact.A device history record review was performed on the guide wire and insertion components (ars and introducer needle) and no relevant manufacturing issues were identified.The customer report of a kinked guide wire could not confirmed through evaluation of the returned sample.No defects or anomalies were observed on the returned guide wire.(con't) other remarks: the guide wire met all relevant dimensional/functional requirements and a device history record review did not reveal any manufacturing related issues.No problem was found on the returned sample; therefore, no further action will be taken.
