Manufacturing review: the device history records have been reviewed with special attention to the subassemblies, material review reports, raw material testing, manufacturing process, and quality control inspection.This lot met all release criteria.There was nothing found to indicate there was a manufacturing related cause for this event.Visual inspection: the balloon size for this product was printed on the balloon hub of the catheter and identified the returned sample as a 6mm x 40cm balloon.A foreign material can be identified in the inflation/deflation port.No other anomalies were noted to the balloon or along the length of the catheter.Functional/performance evaluation: the patency of the guidewire lumen was tested using an in-house 0.035" guidewire and it passed without issue.The inflation hub was connected to an in-house inflation device and the balloon was unable to be inflated.The balloon was cut and peeled back to examine the inflation/deflation ports.A 3.6cm piece of metal was identified within the inflation/deflation port.The metalic body was identified as a broken piece of a processing mandrel from the manufacturing site.Medical records review: medical records were not provided; therefore, a review could not be performed.Image review: images were not provided; therefore a review could not be performed.Conclusion: the investigation was confirmed for foreign material present in the device and inflation issues, as a piece of a processing mandrel was identified within the inflation/deflation port of the catheter.Per the evaluation results, a piece of a processing mandrel from the manufacturing site was identified within the catheter lumen.Therefore, the reported event was determined to be manufacturing related.An ongoing investigation is being conducted to address this issue.Labeling review: the current ifu (instructions for use) states: warnings: do not exceed the rbp recommended for this device.Balloon rupture may occur if the rbp rating is exceeded.To prevent over pressurization, use of a pressure monitoring device is recommended.Precautions: if resistance is felt during post procedure withdrawal of the catheter through the introducer sheath/guide catheter, determine if contrast is trapped in the balloon with fluoroscopy.If contrast is present, push the balloon out of the introducer sheath/guide catheter and then completely evacuate the contrast before proceeding to withdraw the balloon.If resistance is still felt during post procedure withdrawal of the catheter, it is recommended to remove the balloon catheter and introducer sheath/guide catheter as a single unit.Use of the ultraverse 035 pta dilatation catheter: position the balloon relative to the lesion to be dilated, ensure the guidewire is in place, and inflate the balloon to the appropriate pressure.Potential adverse reactions: additional intervention (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.
