Manufacturing review: a manufacturing review was performed.The lot met all release criteria.Visual/microscopic inspection: the sample appeared to be clean.The balloon was not in its original folded configuration.The balloon size for this product is printed on the balloon hub of the catheter and identified the returned sample as a 7mm x 40mm x 75cm balloon.The proximal segment contained the hub and the strain relief.The distal segment contained the rest of the catheter and the balloon.No other anomalies were noted to the catheter.Functional/performance evaluation: the strain relief was removed from the hub.The catheter detachment underneath the strain relief was examined under microscopic magnification and the edges of the detachment were jagged.The catheter detachment was located at the distal end of the y-hub.Sanding marks were noted on the catheter at the point of the detachment.No functional testing could be performed due to the condition in which the sample was returned (i.E.Catheter detachment).Medical records review: as medical records were not provided, a review could not be performed.Image/photo review: no medical images have been made available to the manufacturer.Conclusion: the investigation is confirmed for a catheter detachment, as the catheter detached just distal to the y-hub.The investigation is inconclusive for a leak, as functional testing could not be performed due to the poor sample condition (i.E.Detached catheter).It is unknown whether handling techniques by the user as they removed the catheter from the packaging or prepped the device may have contributed to the reported issue.Based upon the available information a definitive root cause has not been determined.Labeling review: the current ifu (instructions for use) states: precautions: carefully inspect the catheter prior to use to verify that catheter has not been damaged during shipment and that its size, shape, and condition are suitable for the procedure for which it is to be used.Do not use if product damage is evident.Dilatation catheter preparation: prepare the wire lumen of the catheter by attaching a syringe to the wire lumen hub and flushing with sterile saline solution.Use of the ultraverse 035 pta dilatation catheter: position the balloon relative to the lesion to be dilated, ensure the guidewire is in place, and inflate the balloon to the appropriate pressure.
