Additional Manufacturer Narrative
D2b - pro code (product code): fge, lit.G4 - premarket / 510(k) #: k141521, k141597.Device evaluated by mfr: the mustang device was returned to our post market quality assurance laboratory.A visual examination identified that the balloon was not folded which indicates that the balloon was subjected to positive pressure.The rated burst pressure for this device is 24 atmospheres as per mustang specification.The returned device was attached to an encore inflation unit.Positive pressure was applied when di water was observed to be leaking from a balloon pinhole located approximately 1mm distal from the distal markerband.A visual examination of the markerbands identified no issues.A visual and tactile examination identified a shaft kink approximately 10mm distal from the distal end of the strain relief.A visual and tactile examination identified no damage to the tip.This concludes the product analysis.
