It was reported that the procedure was to treat a left upper arm loop axillary-axillary av graft with poor function and stenosis.The 4.0x40mm armada 14 percutaneous transluminal angioplasty (pta) catheter was inflated and ruptured at an unknown pressure.No resistance was noted during advancement, but the physician thought that the stenosis had a jagged edge, which might have caused the balloon to rupture.A non-abbott non compliant balloon was used to complete the procedure.There were no adverse patient effects and there was no clinically significant delay in the procedure.No additional information was provided.

A visual inspection was performed on the returned device and the reported balloon rupture was confirmed.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Additionally, a review of the complaint history identified no other incidents and/or complaints reported from this lot.Balloon material ruptures can be affected by numerous factors such as balloon damage during processing of the balloon material, materials, inflation technique, inflation over rated burst pressure, interactions with other devices, anatomical conditions, a previously implanted stent or insufficient preparation prior to use.Based on the limited information provided, the investigation was unable to determine a conclusive cause for the reported balloon rupture.It is possible that during advancement the balloon became compromised and/or damaged against the anatomy (the stenosis had a jagged edge) or other devices used in the procedure resulting in the reported balloon rupture; however, this could not be confirmed.There is no indication of a product quality issue with respect to manufacture, design or labeling.
