It was reported that the procedure was to treat a moderately calcified, stenosed lesion in the right superficial femoral artery (sfa).A 6mmx40mm armada 35 balloon dilatation catheter (bdc) was advanced to the lesion and inflated once to 3 atmospheres (atm); however, the balloon would not inflate any further.The bdc was removed and re-inserted, this time it inflated to the nominal pressure of 6 atm but would not inflate any further.The bdc was removed, without issue.The experienced scrub tech noted that theballoon was performing as if there was a slow leak or a pin hole.There was no reported adverse patient effect and no clinically significant delays in the procedure.A non-abbott stent was placed, after which a non-abbott balloon was used to post-dilatate and complete the procedure.No additional information was provided.

Visual and functional analysis was performed on the returned device.The reported inflation issue and leak were not confirmed.During testing, the balloon fully inflated to rated burst pressure (rbp) of 20 atmospheres min, with no anomalies noted; thus, the reported leak and inflation issue were not 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 similar incidents and/or complaints from this lot.The investigation was unable to determine a conclusive cause for the reported leak and inflation issue.However, possible factors that can contribute to a leak in the system include, but are not limited to, manufacturing, balloon damage during use, inflation technique, interactions with accessory devices, catheter damage, or insufficient preparation prior to use.Additionally, possible factors that may contribute to difficulty inflating may include, but are not limited to, manufacturing, damage to the inflation lumen, patient anatomical morphology and patient disease state.There is no indication of a product quality issue with respects to the design, manufacture, or labeling of this device.
