    FURTHER INVESTIGATION: THE ACIST SYRINGE KIT IS THE NON-PATIENT CONTACT KIT THAT IS SET UP AND FILLED WITH THE CONTRAST MEDIA AND IS USED IN ANGIOGRAPHIC PROCEDURE WITH ACIST INJECTOR. SIX SYRINGE KITS WERE RETURNED BY THE CUSTOMER TO ACIST FOR INVESTIGATION. EVALUATION OF RETURNED KITS CONFIRMED THAT THE SYRINGES HAD CRACKED AT THE CONTRAST PORT OF THE SYRINGES. ACIST'S INITIAL ANALYSIS INDICATED THAT UNDER WHAT APPEARS TO BE EXTREME CIRCUMSTANCES USING ACIST SYSTEM, THE CONTRAST PORT OF THE SYRINGE MAY FRACTURE DURING THE INJECTION. FURTHER INFORMATION WAS OBTAINED FROM THE FIELD AND IT WAS DETERMINED THE MAJORITY OF REPORTED FRACTURE HAVE OCCURRED WHILE USING A HIGH FLOW RATE AND SMALL CATHETERS. FURTHER INVESTIGATION CONTINUED: ACIST MEDICAL ADVISORY BOARD REVIEWED REPORTS OF FAILURES AND THEY FELT THAT THE DEVICE FAILURE WOULD BE OBVIOUS TO THE USER AND DID NOT POSE A PATIENT RISK. EJECTION OF CONTRAST MEDIA IS MESSY AND THERE IS A CHANGE THAT PERSONNEL IN VERY CLOSE PROXIMITY TO THE DEVICE MIGHT BE SPRAYED WITH CONTRAST. TOPICAL CONTRAST EXPOSURE DOES NOT NORMALLY CONSTITUTE A HEALTH RISK. ALTHOUGH PERSONNEL SHOULD ALWAYS WEAR EYE PROTECTION, THERE IS A VERY SMALL CHANCE THAT THEY COULD HAVE CONJUNCTIVAL EXPOSURE. EYE EXPOSURE TO STANDARD CONTRAST MEDIA DOES NOT NORMALLY CARRY SIGNIFICANT RISK OTHER THAN IRRITATION. DUE TO THE ROUTINE EXPOSURE TO BLOOD AND BIOLOGICAL FLUIDS IN THE CATHETERIZATION LABORATORY ENVIRONMENT, EYE WASH STATIONS SHOULD BE AVAILABLE. BASED ON THESE CONSIDERATIONS, MAB OPINION WAS THAT THIS TYPE OF DEVICE FAILURE, WHILE NOT DESIRABLE, DOES NOT CONSTITUTE A SIGNIFICANT RISK OF HEALTH. SUBSEQUENTLY, ACIST MEDICAL SYSTEMS EXPANDED ITS INVESTIGATION TO DETERMINE THE ROOT CAUSE OF THE PROBLEM. IN COLLABORATION WITH THE CONTRACT MANUFACTURER, ACIST CONDUCTED AN EVALUATION OF THE MANUFACTURING PROCESS AND DETERMINED THAT THE ISSUE WAS ASSOCIATED WITH THE MOLDING PROCESS. A CORRECTIVE ACTION PLAN TO OPTIMIZE THE MANUFACTURING PROCESS HAS BEEN IMPLEMENTED AND ADDITIONAL QUALITY TESTING HAS BEEN DEVELOPED AND IMPLEMENTED TO ELIMINATE THE OCCURRENCE OF THE INCIDENT.
