    Additional Manufacturer Narrative · 1

    WE HAVE RECEIVED THE DEVICE FOR EVALUATION AND WERE ABLE TO VERIFY THE FAILURE. THE TOP (PROXIMAL) RING WELDING EVALUATION DID NOT REVEAL ANY PROBLEMS DURING THE MANUFACTURING PROCESS - WELD WAS DONE CORRECTLY. THE ROOT CAUSE OF THE FAILURE IS INCONCLUSIVE. IT IS POSSIBLE THE EXCESSIVE FORCE AND/OR CALCIFIED VESSEL CONTRIBUTED TO THE FAILURE. PLEASE NOTE THAT WE DO NOT RECOMMEND THE USE OF MOLLRING CUTTER DEVICES FOR CUTTING CALCIFIED MATERIAL SINCE IT MAY DAMAGE THE DEVICE (PLEASE REFERENCE LEMAITRE VASCULAR, INC. IFU PRECAUTION SECTION FOR MORE DETAILS). PLEASE NOTE THAT THE PT IS FINE AND THE CASE WAS DONE SUCCESSFULLY.

    Description of Event or Problem · 1

    THE MOLLRING DEVICE WAS USED FOR ENDARTERECTOMY PROCEDURE. THE CUTTING RING DISENGAGED ITSELF PERPENDICULAR TO THE BOTTOM BLADE UNDER FLUORO. IT WAS ASSUMED THAT THERE WAS NO ISSUE WITH THE CUTTER. THE PHYSICIAN WAS ABLE TO REMOVE THE CORE AND CUTTING RINGS BACK TOGETHER. THE CORE WAS CALCIFIED. UPON INSPECTION, THE TOP RING WAS CAUGHT AROUND THE CORE. WHEN THE CORE WAS REMOVED FROM THE RING, THEN IT WAS FOUND THAT THE TOP RING HAD ACTUALLY BROKEN AT THE WELD AWAY FROM ITS SHAFT AND HAD GOTTEN STUCK IN THE CORE. PT IS FINE AND THE CASE WAS DONE SUCCESSFULLY.
