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 6mm x 40mm balloon.The catheter was kinked 34.6cm and 68.8cm from the distal tip.However after review of the preliminary pictures, the manner in which the device was packaged for return may have contributed to the kinks.No kinks were reported by the user.The balloon appeared to have been previously inflated.No ruptures were noted to the balloon.The inner guidewire lumen was examined underneath the balloon and a crack in the guidewire lumen was noted 5.1cm from the distal tip.The crack was examined under microscopic magnification (10x) and the edges of the crack were jagged and stretched.Functional/performance evaluation: the patency of the guidewire lumen was then tested using an in-house 0.035¿ guidewire and it passed without issue.Upon inflation, water was seen exiting out the distal tip of the balloon.The balloon was unable to be inflated to nominal pressure due to the leak.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 investigation is inconclusive for material rupture, as the balloon could not be inflated to rated burst pressure due to a crack in the guidewire lumen that resulted in a leak from the distal tip of the balloon.The root cause for the crack in the guidewire lumen is unknown.It is unknown whether the crack was a result of an incorrectly formed weld bond between the inner shaft and dual lumen during the manufacturing of the device.Operator awareness training was conducted at the manufacturing site as a pro-active measure to draw attention to weld bond quality.Labeling review: the current ultraverse 035 pta catheter instructions for use (ifu) provides general instructions for use of the device, as well as warnings, precautions, and potential complications associated with the device.(b)(4).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.
