Product performance engineering reviewed the incident information; however, the product was not returned to abbott vascular for 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 incidents reported from this lot.The investigation determined the reported difficulty to advance and balloon rupture appears to be related to case circumstances of the procedure.In this case, based on the reported information, it is likely that during advancement through the challenging, the balloon outer surface became compromised and/or damaged against resulting in the balloon rupture during inflation.It should be noted that instructions for use (ifu) states: balloon pressure should not exceed the rated burst pressure (rbp).The reported ifu violation does not appear to have caused or contributed to the reported complain.It is likely that the balloon became damaged against the challenging anatomy.There is no indication of a product quality issue with respect to manufacture, design, or labeling; therefore, no corrective action is required.
