    Additional Manufacturer Narrative · 1

    THE RETURNED VALVE WAS PATENT AND MET THE REQUIREMENTS FOR LEAK, REFLUX AND PREIMPLANTATION TESTING. HOWEVER, IT DID NOT MEET THE REQUIREMENTS FOR PRESSURE-FLOW TESTING DUE TO PRESENCE OF PROTEINACEOUS DEBRIS WITHIN THE INTERIOR OF THE VALVE. PROTEINACEOUS DEBRIS WITH IN THE VALVE MAY HOLD PRESSURE-FLOW CONTROLLING MECHANISMS OPEN, RESULTING IN FLUID REFLUX AND/OR SIPHONING. A REVIEW OF THE MFG RECORDS SHOWED NO ANOMALIES. ALL OF OUR VALVES ARE 100% TESTED AT THE TIME OF MANUFACTURE.

NO ADVERSE IMPACT OR INJURY TO THE PT WAS REPORTED.
