As reported, the aviator plus.014¿ 6.0mmx40mm 142cm was inserted and blown up to nominal pressure.However, the balloon broke at nominal pressure because of the large calcified plaque in vessel.There was an injury to the patient.They took picture and saw large extravasation.Sheath, angioguard, and stent were placed with no issues.The sheath was exchanged and non-cordis covered stent was placed, followed by 6x40 non-cordis balloon.No extravasation seen on post picture in 2 angles.According to the surgeon, there was plaque rupture with the deployment of stenting and balloon angioplasty.The heavily calcified plaque may have caused the balloon to rupture.The patient required a secondary procedure, stenting with covered stent x 2.As per the sales rep, the patient experienced symptoms of a stroke, the patient was non-verbal/non-motor responses and was sent directly to catscan.The patient began recovering motor functions during the scan.The lesion had moderate to severe plaque calcification.There was no vessel tortuosity.The percentage of stenosis was greater than 50%.The device was not used for a chronic total occlusion and was stored and handled per the instructions for use (ifu).The device was prepped normally per ifu by maintaining.There was no difficulty of removing the stylet or any of the sterile packaging components, removing the product from the hoop, removing the protective balloon cover.There were no kinks or other damages noted prior to inserting the product into the patient.The same indeflator was used successfully with other devices.There was no resistance/friction noted while inserting the balloon through the rotating hemostatic valve.There was no difficulty advancing the balloon catheter through the vessel and difficulty crossing the lesion.The products were removed intact in one piece from the patient.The device is expected to be returned for evaluation.Concomitant medical products: unknown sheath; viabahn covered stent; mustang balloon.

After further review of additional information received the following sections g4,g7,h2,h3 and h6 have been updated accordingly.As reported, the aviator plus.014¿ 6.0mm x 40mm 142cm was inserted and blown up to nominal pressure.However, the balloon broke at nominal pressure because of the large calcified plaque in vessel.There was an injury to the patient.They took picture and saw large extravasation.Sheath, angioguard, and stent were placed with no issues.The sheath was exchanged and non-cordis covered stent was placed, followed by 6x40 non-cordis balloon.No extravasation seen on post picture in 2 angles.According to the surgeon, there was plaque rupture with the deployment of stenting and balloon angioplasty.The heavily calcified plaque may have caused the balloon to rupture.The patient required a secondary procedure, stenting with covered stent x 2.As per the sales rep, the patient experienced symptoms of a stroke, the patient was non-verbal/non-motor responses and was sent directly to cat scan.The patient began recovering motor functions during the scan.The lesion had moderate to severe plaque calcification.There was no vessel tortuosity.The percentage of stenosis was greater than 50%.The device was not used for a chronic total occlusion and was stored and handled per the instructions for use (ifu).The device was prepped normally per ifu by maintaining.There was no difficulty of removing the stylet or any of the sterile packaging components, removing the product from the hoop, removing the protective balloon cover.There were no kinks or other damages noted prior to inserting the product into the patient.The same indeflator was used successfully with other devices.There was no resistance/friction noted while inserting the balloon through the rotating hemostatic valve.There was no difficulty advancing the balloon catheter through the vessel and difficulty crossing the lesion.The products were removed intact in one piece from the patient.The device is expected to be returned for evaluation.The product was returned for analysis.One non-sterile aviator plus.014 6.0 x 40 142cm was received for analysis coiled inside a plastic bag.A guidewire was also returned inside the plastic bag.Per visual analysis, the balloon appears to have been previously inflated, and it was observed burst.Also, an angioguard stent was observed inserted through the device, as received.No other anomalies were observed.Per sem analysis, results revealed the balloon burst was caused by a rupture on the balloon surface.The inner surface presented no anomalies adjacent to the balloon rupture.The outer surface presented evidence of scratch marks adjacent to the balloon rupture.This type of damage is commonly caused during the interaction of the balloon material with a sharp object or mechanical damage.It is very likely that the same factors that caused the observed scratch marks on the balloon outer surface probably led to the ruptured condition found on the received balloon.It appears the balloon material near the rupture was torn with a sharp object from the outside of the balloon.No other anomalies were observed during the sem analysis.A product history record (phr) review of lot 17672697 revealed no anomalies or non-conformances during the manufacturing and inspection processes that can be associated with the reported event.The reported ¿balloon burst - at/below rbp¿ was confirmed through analysis of the returned device.Based on the information available for review, vessel characteristics of a large calcified plaque likely contributed to the reported event as noted by the physician.Analysis revealed scratch marks adjacent to the balloon rupture on the outer surface of the balloon.It appears the balloon material near the rupture was torn with a sharp object from the outside of the balloon.Risks associated with angioplasty procedures include vascular dissection in this case (extravasation was specifically reported).These are well-known and extensively documented potential complication of this type of procedure and is listed in the instructions for use (ifu) as such.Vessels that are resistant to angioplasty have a higher risk of intimal plaque rupture during interventional procedures.Review of the available information suggests that these lesion characteristics and possibly procedural factors may have contributed to the balloon burst and vessel extravasation with plaque rupture which ultimately resulted in the patient experiencing stroke like symptoms.A calcified/resistant lesion can cause damage to the balloon and result in vessel damage during angioplasty.According to the instructions for use ¿prior to use, the device should be examined to verify functionality and integrity, and ensure that its size is suitable for the specific procedure.Do not exceed the rated burst pressure recommended on the label.The rated burst pressure is based on the results of in-vitro testing.At least 99.9% of the balloons (with a 95% confidence) will not burst at or below their rated burst pressure.Use of a pressure-monitoring device is recommended to prevent over-pressurization.Use only the recommended balloon inflation medium (a 50/50 mixture by volume of contrast medium and normal saline).Never use air or any gaseous medium to inflate the balloon.Potential complications, which may lead to additional intervention, include, but are not limited to: embolism, hemorrhage, stroke, thrombosis, transient ischemic attack, vascular complications (e.G.Intimal tear, dissection, pseudoaneurysm, perforation, rupture, spasm, occlusion).¿ neither the phr nor the information available suggests a design or manufacturing related cause for the reported event.Therefore, no corrective or preventive action will be taken at this time.
