Analysis/device evaluation: upon receipt, visual examination revealed a severe kink at the proximal balloon bond and surface scratches on the balloon.Microscopic visual inspection revealed a rupture in the middle of the balloon, approximately 48mm from the distal marker band.The rupture was examined under magnification and was measured to be approximately 1.38mm long.Functional testing determined the balloon was unable to be fully inflated, due to the material rupture.A lot history review revealed this is the only complaint associated with 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 the material rupture in the middle of the balloon.There was nothing found to indicate there was a manufacturing related cause for this event.A definitive root cause for the rupture could not be determined.Although requested, patient weight was unavailable.In the physician¿s opinion, the highly calcified lesion caused the material rupture.If additional information becomes available, a supplement 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.
