Manufacturing review: a manufacturing review was conducted and there was nothing found to indicate there was a manufacturing related cause for this event.The lot met all release criteria.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 14 mm x 6 cm 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 and were observed to be jagged and stretched, indicating that excessive force was likely applied to the catheter.Additionally, kinks were observed throughout the length of the catheter.As no kinks were reported by the user., the manner in which the device was packaged for return may have contributed to the kinks in the catheter.No other anomalies were identified to the device.Functional/performance evaluation: functional evaluation could not be 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.Based upon the condition in which the sample was returned, the investigation is confirmed for a break at the proximal balloon glue joint and sheath related retraction issues.The investigation is unconfirmed for torn material.Based on the visual inspection of the break, it appeared that excessive force may have been applied to the catheter shaft during removal, as the edges of the break were uneven and stretched.However, the definitive root cause for the outer shaft break could not be 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.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.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.
