    INFORMATION REGARDING SUSPECT MEDICAL DEVICE: COMMON DEVICE NAME: NOT AVAILABLE. REGULATION NAME: HEMOSTATIC DEVICE FOR INTRALUMINAL GASTROINTESTINAL USE. PRODUCT CODE: QAU. INFORMATION REGARDING ALL MANUFACTURERS: PMA/510(K) #: K200972. INVESTIGATION EVALUATION: OUR LABORATORY EVALUATION OF THE PRODUCT SAID TO BE INVOLVED CONFIRMED THE REPORT. ALL COMPONENTS WERE NOT INCLUDED IN THE RETURN (ONLY ONE CATHETER WAS RETURNED) THEREFORE A COMPLETE EVALUATION WAS NOT POSSIBLE. THE DEVICE WAS RETURNED WITH THE ON/OFF SWITCH IN THE "ON" POSITION. THE RED ACTIVATION KNOB WAS ENGAGED IN THE HANDLE INDICATING ACTIVATION OF THE CARBON DIOXIDE (CO2) CARTRIDGE. WHEN TESTED AS RETURNED, THE DEVICE DID NOT SPRAY. THE DEVICE DID NOT DISCHARGE WHEN DEACTIVATED. THE LANCE POSITION WAS MEASURED AND FOUND TO BE POSITIONED CORRECTLY. A VISUAL EXAMINATION OF THE O-RING AND LANCE INSIDE THE HANDLE SHOWED BOTH COMPONENTS TO BE POSITIONED CORRECTLY INSIDE THE HANDLE AND THE LANCE TO BE BEVELED. THE INSPECTION OF THE CO2 CARTRIDGE AND REGULATOR (LANCE AND O-RING) CONFIRM THE DEVICE WAS OF THE CURRENT DESIGN. WHEN RETESTED WITH A NEW CO2 CARTRIDGE, THE DEVICE SPRAYED CONSTANTLY WITHOUT PRESSING THE ACTIVATION BUTTON. THE CATHETER WAS ATTACHED TO THE DEVICE FOR TESTING AND SHOWN TO BE CLEAR AS THE DEVICE CONTINUED TO SPRAY CONSTANTLY. THE DEVICE WAS DISASSEMBLED AND POWDER WAS SEEN IN THE TUBES CONNECTING THE POWDER CHAMBER, ON/OFF VALVE, AND LOW PRESSURE VALVE. THE TUBES WERE DISCONNECTED FOR REMOVAL OF THE POWDER AND NO CLUMPS WERE OBSERVED. A VISUAL INSPECTION OF HOLE IN THE BOTTOM OF THE POWDER CHAMBER SHOWED IT TO BE CLEAR. THE LOW PRESSURE VALVE WAS DISSEMBLED AND EVALUATED. ALL THE INTERNAL COMPONENTS WERE INTACT. HOWEVER, POWDER WAS OBSERVED ALONG THE INSIDE WALL OF THE VALVE, AROUND THE BASE OF THE ACTIVATION BUTTON, AND AROUND THE O-RINGS INSIDE THE VALVE. A PRODUCT DISCREPANCY OR ANOMALY THAT COULD HAVE CONTRIBUTED TO THIS REPORTED OCCURRENCE WAS NOT OBSERVED. THE DEVICE HISTORY RECORD FOR THE LOT NUMBER SAID TO BE INVOLVED WAS REVIEWED. A DISCREPANCY OR ANOMALY WAS NOT OBSERVED WITH THE PRODUCT THAT WAS RELEASED FOR DISTRIBUTION. INVESTIGATION CONCLUSION: POWDER WAS OBSERVED AROUND THE COMPONENTS AND O-RINGS INSIDE THE LOW PRESSURE VALVE. IT IS UNKNOWN HOW THE POWDER ENTERED THE VALVE. IT IS POSSIBLE THAT PRESSURE BACK FLOW OCCURRED DUE TO POWDER CLOGGING THE DEVICE AND/OR CATHETERS OR DUE TO THE CARBON DIOXIDE CARTRIDGE EMPTYING COMPLETELY, WHICH CAN SEND POWDER BACK INTO THE LOW PRESSURE VALVE AND CAUSE THE OBSERVATIONS FOUND DURING THE EVALUATION. CATHETER OCCLUSION CAN BE A CAUSE OF THIS DEVICE INTERNALLY CLOGGING AND NOT BEING ABLE TO SPRAY POWDER. HOWEVER, WE COULD NOT CONDUCT A COMPLETE INVESTIGATION BECAUSE THE ONLY ONE CATHETER WAS RETURNED FOR EVALUATION. THIS LIMITS OUR ABILITY TO CONCLUSIVELY DETERMINE A CAUSE. CATHETER OCCLUSION CAN BE RELATED TO THE HANDLING OF THE DEVICE DURING THE PROCEDURE. TO ASSIST THE USER, THE INSTRUCTIONS FOR USE (IFU) STATES THE FOLLOWING, "NOTE: DO NOT TEST DEVICE PRIOR TO INSERTION INTO ENDOSCOPE ACCESSORY CHANNEL AS THIS MAY INCREASE RISK OF CATHETER OCCLUSION." THE IFU ALSO STATES, "PRECAUTION: TO AVOID CATHETER OCCLUSION, DO NOT PLACE CATHETER DIRECTLY IN CONTACT WITH BLOOD AND/OR MUCOSA, INCLUDING ANY POOLED BLOOD AND DO NOT ASPIRATE BLOOD WHILE CATHETER IS IN ACCESSORY CHANNEL. NOTE: IF CATHETER BECOMES OCCLUDED, TURN RED VALVE TO CLOSED POSITION, REMOVE CATHETER FROM ENDOSCOPE AND REPLACE WITH EXTRA CATHETER PROVIDED IN PACKAGE." PRIOR TO DISTRIBUTION, ALL HEMOSPRAY ENDOSCOPIC HEMOSTATS ARE SUBJECTED TO A VISUAL INSPECTION TO ENSURE DEVICE INTEGRITY. A REVIEW OF THE DEVICE HISTORY RECORD CONFIRMED THAT THE LOT SAID TO BE INVOLVED MET ALL MANUFACTURING REQUIREMENTS PRIOR TO SHIPMENT. CORRECTIVE ACTION: CORRECTIVE ACTION IS NOT WARRANTED AT THIS TIME BASED ON THE QUALITY ENGINEERING RISK ASSESSMENT. QUALITY ASSURANCE WILL CONTINUE TO MONITOR FOR COMPLAINT TRENDS AND REASSESS THE RISK ASSESSMENT RESULTS AS POST MARKET FEEDBACK CONTINUES TO BECOME AVAILABLE.

    Description of Event or Problem · 1

    DURING A HEMOSTASIS PROCEDURE, THE PHYSICIAN SELECTED A COOK HEMOSPRAY ENDOSCOPIC HEMOSTAT. THE DEVICE INITIALLY FIRED [SPRAYED] BUT WOULD NOT FIRE AGAIN. THE PHYSICIAN SWITCHED TO THE SECOND CATHETER BUT IT STILL WOULD NOT WORK. ADDITIONAL INFORMATION RECEIVED ON 29 SEPTEMBER 2020 STATED: THE PHYSICIAN ACHIEVED HEMOSTASIS WITH THE DEVICE IN QUESTION. THEY WANTED TO APPLY MORE [POWDER] BUT WERE UNABLE TO DO SO. THE NURSE DISENGAGED THE SAFETY TO OPERATE THE DEVICE BUT THEY DID NOT DISENGAGE THE ACTIVATION KNOB. OTHER THAN THE DEPLOYED POWDER, A SECTION OF THE DEVICE DID NOT REMAIN INSIDE THE PATIENT¿S BODY. THE PATIENT DID NOT REQUIRE ANY ADDITIONAL PROCEDURES DUE TO THIS OCCURRENCE. ACCORDING TO THE INITIAL REPORTER, THE PATIENT DID NOT EXPERIENCE ANY ADVERSE EFFECTS DUE TO THIS OCCURRENCE.
