Analysis/device evaluation: visual examination notes the catheter was returned inside an introducer sheath.The introducer sheath is believed to be the unit used during the procedure.The distal end of the catheter was severely wrinkled, which was not allowing the catheter to be removed from the returned introducer sheath.A kink was noted at the distal end of the strain relief.To accomplish functional testing, the introducer sheath was flushed and the catheter was advanced through the introducer sheath to reveal the complete length of the 120 mm balloon.Functional testing determined the balloon could not be inflated due to a longitudinal material rupture which was identified to be approximately 60mm from the proximal marker band.Microscopic visual inspection revealed a longitudinal material rupture, which appears to be "s" shaped in nature.A lot history review revealed this is the only complaint associated with a balloon rupture for this lot.A device history record (dhr) review was performed and noted the device was manufactured to specification prior to being released for distribution.There was nothing found to indicate there was a manufacturing related cause for this event.Conclusion: returned product analysis confirmed an 's' shaped longitudinal material rupture, which is approximately 60 mm from the proximal marker band.There was nothing found to indicate a manufacturing related cause for this event.A definitive root cause for the rupture could not be determined.Although requested, patient demographics and additional event details were unavailable.It is unknown if procedural issues contributed to the reported event.If additional information is obtained, a supplemental report will be submitted with all relevant information.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.
