It was reported that during an angioplasty procedure, the pta balloon allegedly detached from the catheter at 18 atm.Reportedly, the detached balloon got caught on the guide wire during retraction.The sheath, balloon, and guide wire were removed as a single unit.Another balloon was used to complete the procedure.There was no reported patient injury.

Manufacturing review: the device history records were reviewed with special attention to the raw materials, subassemblies, manufacturing process and quality control testing.This lot met all release criteria.There was nothing found to indicate there was a manufacturing related cause for this event.Visual/microscopic inspection: the device was returned.The balloon size for this product is printed on the balloon hub of the catheter and identified the returned sample as a 14mm x 6cm balloon.The balloon was returned detached from the catheter.The distal end of the balloon had been pulled through the proximal end, resulting in the balloon being prolapsed over itself, likely indicating retraction issues.Unraveled fibers were present on the very proximal and distal ends of the balloon.The balloon catheter weld bond was examined under microscopic magnification.The weld bonds appeared to be consistent around the entire circumference of the bond, with no defects noted.Both marker bands were present on the catheter.No other anomalies were noted on the returned device.Functional/performance evaluation: no further functional testing could be performed due to the poor sample condition (i.E.Detached balloon).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: based on the condition in which the sample was received, the investigation is confirmed for a balloon detachment, retraction issues and loss of bond.Per the reported event details, the procedure was performed with a stent present.Therefore, it is possible that an interaction with the stent may have contributed to the reported issues.However, the definitive root cause could not be determined based upon the available information.Labeling review: the current ifu (instructions for use) states: warnings: when the catheter is exposed to the vascular system, it should be manipulated while under high quality fluoroscopic observation.Do not advance or retract the catheter unless the balloon is fully deflated.If resistance is met during manipulation, determine the cause of the resistance before proceeding.Applying excessive force to the catheter can result in tip breakage or balloon separation.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, determine if contrast is trapped in the balloon with fluoroscopy.If contrast is present, push the balloon out of the sheath 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 guidewire/introducer sheath as a single unit.Use of the atlas gold pta dilation catheter: apply negative pressure to fully evacuate fluid from the balloon.Confirm that the balloon is fully deflated under fluoroscopy.While maintaining negative pressure and the position of the guidewire, withdraw the deflated dilatation catheter over-the-wire through the introducer sheath.Use of a gentle clockwise motion may be used to help facilitate catheter removal through the introducer sheath.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.
