It was reported that the procedure was to treat a moderately calcified, moderately tortuous, 90% stenosed lesion in the popliteal artery.A 4.0x40mm armada 14 percutaneous transluminal angioplasty (pta) catheter was prepared for use, advanced and positioned to pre-dilate the lesion.The balloon was inflated to nominal pressure, ruptured on the first inflation.Another armada pta was used to successfully complete the procedure.There were no adverse patient effects and no clinically significant delay in the procedure.No additional information was provided.

Visual, functional and scanning electron microscopy (sem) analysis were performed on the returned device.The reported balloon rupture was not confirmed; however, there was a tear observed through the inflation port on the inner member and a leak confirmed on the inner member.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.The investigation determined that the reported balloon rupture and/or noted leak was due to a tear noted to the inner member.Although a cause for the tear could not be determined, there was no leak noted during preparation for use indicating that the damage was not pre-existing.Additionally, based on the evaluation of the returned unit and sem analysis, the inner member damage may be attributed to mechanical damage and may suggest that an object was inserted into the inflation port; however, this could not be confirmed.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.
