COMPLAINT #(B)(4).

Additional Manufacturer Narrative

(4111/3221) THREE ATTEMPTS WERE MADE TO CONTACT THE INITIAL REPORTER OF THE INCIDENT, IN ORDER TO OBTAIN MORE INFORMATION ON THE EVENT AND THE INVOLVED PRODUCT. THE FIRST ANSWER OBTAINED IS AS FOLLOWS: "GRAFT SERIAL NUMBER: (B)(6)PATIENT ¿ 50 YEAR OLD FEMALE, WEIGHT 88KG". THE SERIAL NUMBER WAS LATER CLARIFIED AS: (B)(6) AND WE LEARNED THAT "THE PATIENT WAS DISCHARGED FROM [THE] FACILITY IN SATISFACTORY CONDITION."(3331/213) SINCE WE OBTAINED THE SERIAL NUMBER, THE COMPLETE DEVICE HISTORY RECORD WAS REVIEWED BY THE QUALITY ASSURANCE SUPERVISOR. THIS REVIEW DID NOT FIND ANY DISCREPANCY CONCERNING A LOCALIZED LEAK.(4112/170) THE CASE WAS FURTHER REVIEWED BY THE CORPORATE MEDICAL OFFICER. HIS ASSESSMENT IS AS FOLLOWS:"THE EVENT DESCRIBES A PATIENT UNDERGOING A AORTO BIFEMORAL BYPASS USING A HEMASHIELD GOLD KNITTED BIFURCATED. AFTER THE COMPLETION OF THE PROXIMAL ANASTOMOSIS ON THE ABDOMINAL AORTA AND DECLAMPING A LEAK WAS OBSERVED AT THE GRAFT BIFURCATION AT THE ANASTOMOSIS SEAM LINE. THE HOLE WAS SUCCESSFULLY REPAIRED WITH A PROLENE SUTURE. THE GRAFT REMAINED IMPLANTED AND THE PATIENT DID NOT EXPERIENCE ANY ADVERSE EVENT DUE TO THE GRAFT DEFECT. THE OUTCOME OF THE SURGERY WAS UNALTERED. SINCE THE DEFECT WAS DETECTED AFTER THE COMPLETION OF THE PROXIMAL ANASTOMOSIS IT IS LIKELY THAT THE HOLE WAS PRESENT BEFORE THE GRAFT WAS USED AS THE BIFURCATION IS NOT SUBJECTED TO ANY FORCE OR TRAUMA AT THIS POINT OF THE PROCEDURE. ALTHOUGH WHEN DETECTED THE DEFECT CAN BE EASILY REPAIRED, IF IT IS SMALL AND NOT IMMEDIATELY EVIDENT IT COULD LEAD TO SERIOUS BLEEDING NEEDING INTERVENTION IN THE POST-OPERATIVE PERIOD OR EVEN LATER."(25) BASED ON THE ABOVE MEDICAL ASSESSMENT, THE CAUSE IS TRACED TO MANUFACTURING. THEREFORE, A NON-CONFORMITY REPORT HAS BEEN INITIATED IN ORDER TO INVESTIGATE THE CAUSE AND TAKE APPROPRIATE CORRECTIVE ACTIONS IF NECESSARY.

Additional Manufacturer Narrative

THE DEVICE IS NOT ACCESSIBLE AS IT REMAINED IMPLANTED IN THE PATIENT. THE HISTORY RECORDS FOR LOT 19B27 WERE REVIEWED, NO DISCREPANCY FOUND CONCERNING A LOCALIZED LEAK. THE REVIEW OF POST-MARKETING HISTORICAL DATA INDICATED THAT NO OTHER SIMILAR COMPLAINT WAS REPORTED FOR THE SAME STERILIZATION LOT NUMBER 19B27. A RETENTION SAMPLE FROM THE SAME STERILIZATION LOT AS THE INVOLVED DEVICE , WITH A BIFURCATION , WAS SELECTED AS REPRESENTATIVE OF THE PRODUCT INVOLVED IN THE COMPLAINT. THIS RETENTION SAMPLE UNDERWENT WATER PERMEABILITY TESTING. THE TEST RESULT INDICATED A VALUE WELL WITHIN PRODUCT SPECIFICATIONS (< 5 ML/CM²/MIN). TWO ATTEMPTS TO CONTACT THE INITIAL REPORTER IN ORDER TO OBTAIN MORE INFORMATION ON THE EVENT AND THE INVOLVED PRODUCT WERE MADE. RESULTS ARE PENDING. THE INVESTIGATION IS STILL ONGOING. A FOLLOW UP REPORT WILL BE SENT UPON COMPLETION OF THE INVESTIGATION.
