Manufacturing review: the device lot number was not provided; therefore, the device history records were not reviewed.Visual/microscopic inspection: the balloon size for this product is printed on the balloon hub of the catheter and identified the returned sample as a 18mm x 4cm balloon.A complete circumferential outer shaft break was observed at the proximal balloon glue joint.The inner polyimide was noted to be intact.The break was examined under microscopic magnification (30x) and were observed to be jagged and stretched, indicating that excessive force was likely applied to the catheter.No other anomalies were identified to the device.Functional/performance evaluation: functional evaluation was not performed, due to sample condition (i.E.Circumferential catheter break).Medical records review: medical records were not provided; therefore, a review could not be performed.Image/photo review: images/photos were not provided; therefore, a review could not be performed.Conclusion: the device was returned.The catheter was examined under magnification and a complete circumferential break was noted at the glue joint, confirming the investigation for break.However, the investigation is inconclusive for the reported retraction issues, as the device was not able to be functionally tested due to the sample condition (e.G.Break at glue joint).The definitive root cause could not be determined based upon available information.It is unknown if patient and/or procedural issues contributed to the event.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.Do not continue to use the balloon catheter if the shaft has been bent or kinked.Dilatation catheter preparation: remove catheter from package.Verify the balloon size is suitable for the procedure and the selected accessories accommodate the catheter as labeled.Remove the balloon guard by grasping the balloon catheter just proximal to the balloon and with the other hand, gently grasp the balloon protector and slide distally off of the balloon catheter.Use of the atlas pta dilatation catheter: apply negative pressure to fully evacuate fluid from the balloon.Confirm that the balloon is fully deflated under fluoroscopy.While maintaining negative pressure and the position of the guidewire, withdraw the deflated dilatation catheter over the wire through the introducer sheath.Use of a gentle counterclockwise motion may be used to help facilitate catheter removal through the introducer sheath.The information provided by bard represents all of the known information at this time.Despite good faith efforts to obtain additional information, the complainant / reporter was unable or unwilling to provide any further patient, product, or procedural details to bard.
