Updated: d9 (device availability), h3 (device evaluated by manufacturer), h6 (investigation findings, investigation conclusions).Added: h6 (type of investigation).The fogarty catheter was not received at our product evaluation laboratory for evaluation.Therefore, a product non-conformance or device failure associated to manufacturing or design could not be confirmed.The manufacturing records were reviewed and there is no indication of a related nonconformance; all process parameters were met, and inspections passed successfully.As part of the manufacturing process a 100% of the units go through a balloon winding and full visual inspection process.Instructions for use provides warnings and cautions related to the balloon and the handling of the catheter as a guideline to follow: "balloon rupture and catheter separation as a result of excessive pull force applied to remove adherent material are the most frequent causes of reported failures.The possibility of balloon rupture must be taken into account when considering the risks involved in any embolectomy procedure" and "to minimize the risk of vessel damage, balloon rupture, or tip detachment, do not exceed the maximum recommended inflation volume and pull force for each size catheter".Since the affected unit was not returned for evaluation, a product non-conformance or device failure could not be confirmed.
