Manufacturer Narrative
|
Device code 2017 - failure to follow steps / instructions visual analysis was performed on the returned unit.The reported tip detachment was confirmed during analysis.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 complaints.It should be noted that the supera instruction for use states: prepare the vessel / duct utilizing standard angioplasty technique using a balloon size greater than the stent outer diameter.Refer to the balloon¿s instructions for use.Per the pre-dilation sizing table in the ifu, a 4.5 mm stent requires a recommended minimum inflated balloon diameter of greater that 4.5 mm.In this case, it was reported that the lesion was dilated with a non-abbott balloon (4mm) to the break pressure.After using the balloon, the lesion was uniform, and the physician did not want to dilate more, and they tried to place the supera stent (4.5x120).It could not be determined if inadequate vessel preparation contributed to the difficulties.The investigation was unable to determine a cause for the reported tip separation and subsequent patient effects.The reported patient effects of hemorrhage, ischemia and death are listed in the supera instructions for use as known potential adverse effects of peripheral percutaneous intervention.In this case, a conclusive cause for the patient effects, and the relationship to the product, if any, cannot be determined.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.B5: case details h6: device code 2017 added.
