    Narratives

    Additional Manufacturer Narrative · 0

    AFTER A THOROUGH REVIEW OF THE EQUIPMENT AND PROCEDURAL ASPECTS AT THE HOSPITAL AND GIVEN THE ISOLATED AND CLUSTERED OCCURRENCE OF THESE INFECTIONS, IT IS SURGEONS OPINION THAT THESE INFECTIONS WERE UNRELATED TO THE NAVISWISS TECHNOLOGY. RATHER, IT APPEARS TO BE A RESULT OF BASIC PROCEDURAL ISSUES WITHIN THE RE-PROCESSING DEPARTMENT, WHICH HAVE NOW BEEN RECTIFIED THROUGH ADDITIONAL TRAINING MEASURES. THESE TRAINING MEASURES WERE CARRIED OUT ON APRIL 19TH, 2023 AND INCLUDED A THOROUGH REVIEW OF BASIC HYGIENIC PROCESSES AND THE WELL DESCRIBED NAVISWISS RE-PROCESSING INSTRUCTIONS. FOLLOWING THIS INITIATIVE, THE ISSUE HAS NOT RECURRED. AGAIN, IT IS SURGEON OPINION THAT THESE 3X CASES OF POST-OPERATIVE INFECTION WERE UNRELATED TO THE NAVISWISS PLATFORM. PRODUCT WAS NOT RETURNED FOR INVESTIGATION.

NAVISWISS ADMITS THAT AT THE TIME OF REPORTING THE EVENT, IT WAS NOT AWARE THAT A SEPARATE REPORT WAS REQUIRED FOR EACH EVENT IN A SERIES OF REPORTABLE MDR EVENTS, AS REQUIRED BY THE FDA GUIDANCE DOCUMENT "MEDICAL DEVICE REPORTING FOR MANUFACTURERS, GUIDANCE FOR INDUSTRY AND FOOD AND DRUG ADMINISTRATION STAFF". THE CURRENT REPORT IS INTENDED TO REMEDY THE OMISSION OF NOT HAVING SUBMITTED A SEPARATE MDR REPORT FOR EACH EVENT. PLEASE REFER TO FOLLOWING NEW REPORTS: - MDR 3017123055-2024-00002.

    Description of Event or Problem · 0

    A SURGEON PERFORMED A REVIEW OF HIS MOST RECENT 118 TOTAL HIP ARTHROPLASTY (THA) CASES THAT INVOLVED THE USE OF THE NAVISWISS TECHNOLOGY. THIS REVIEW WAS TRIGGERED BY THE INCIDENCE OF 3 OUT OF 118 CASES PRESENTING WITH POST-OPERATIVE INFECTION THAT REQUIRED ONGOING MANAGEMENT. THE SINGLE INCIDENTS OCCURED IN (B)(6) 2022 AND WERE NOT REPORTED AS SINGLE INCIDENTS TO NAVISWISS. IN MARCH 2023 NAVISWISS WAS INFORMED REGARDING THE SITUATION. NO ALLEGATION WAS MADE AGAINST THE MEDICAL DEVICE, FURTHERMORE THE SURGEON LOCATED THE ROOT CAUSE IN THE IN-HOUSE REPROCESSING PROCESS (NON-COMPLIANCE). SEE ALSO SECTION B7. NAVISWISS CONSIDERED THIS CASE AS NOT REPORTABLE, AS THE DEVICE, ACCORDING TO THE SURGEON, WAS NOT THE CAUSE OF THE INFECTIONS. DURING AN AUDIT THIS CASE WAS REVIEWED AND CONSIDERED AS REPORTABLE. THIS CAUSED A DELAY IN REPORTING.
