Qn# (b)(4).The report of a damaged guide wire could not be confirmed through investigation of the returned sample.The customer returned one unopened sac kit for analysis.Visual analysis revealed no obvious defects or anomalies with the returned kit.The customer reported that the damage was found during use on the patient.Therefore, it is being assumed that the unopened kit returned for analysis is a representative sample.The kit was opened to further analyse the components.The guide wire length measured 456mm via calibrated ruler, which was within the specification limits of 450-458 mm per the guide wire product drawing.The guide wire outer diameter measured 0.618mm via calibrated micrometer, which was within the specification limits of 0.610-0.635 mm per the guide wire product drawing.Dimensional inspection of the actual guide wire could not be performed as it was not returned for evaluation.The guide wire was functionally tested per the instructions for use (ifu) provided with this kit, which states "insert desired tip of spring-wire guide through introducer needle into artery (until depth-marking [if provided] on wire enters hub of needle)." the guide wire was inserted through the returned 18ga introducer needle.The guide wire was able to pass through the needle with little to no resistance.Functional inspection of the actual guide wire could not be performed as it was not returned for evaluation.A manual tug test confirmed that the distal and proximal welds were secure and intact.The ifu provided with the kit informs the user, "precaution: use care when removing spring-wire guide.If resistance is encountered, remove spring-wire guide and catheter simultaneously.Use of excessive force may damage catheter or spring-wire guide." a device history record review was performed, and no relevant findings were identified.Based on the customer report and without the reported sample, the potential root cause cannot be determined at this time.Tele flex will continue to monitor and trend for reports of this nature.
