    EVAL: WE COULD NOT CONFIRM THE REPORT BECAUSE THE PRODUCT SAID TO BE INVOLVED WAS NOT RETURNED TO COOK ENDOSCOPY FOR EVAL. AFTER A REVIEW OF THE DEVICE HISTORY RECORD FOR THE LOT NUMBER SAID TO BE INVOLVED, WE CAN REPORT NO DISCREPANCIES OR ANOMALIES WERE OBSERVED. WE WERE UNABLE TO CONDUCT A SAMPLE TEST FROM THIS LOT BECAUSE NONE OF THE PRODUCTS FROM THIS LOT REMAINED IN FINISHED GOODS INVENTORY. A REVIEW OF THE TWELVE MONTH COMPLAINT HISTORY FOR THIS PRODUCT WAS CONDUCTED. BASED ON THIS REVIEW, THE LIKELIHOOD OF THIS TYPE OF REPORT IS REMOTE. CONCLUSIONS: INFO PROVIDED WITH THIS REPORT INDICATES THE ACUSNARE WAS USED TO PERFORM A "COLD" POLYPECTOMY (I.E. AN ELECTROSURGICAL UNIT WAS NOT USED WITH THE ACUSNARE DEVICE). THE INTENDED USE FOR THE ACUSNARE POLYPECTOMY SOFT SNARE LISTED IN THE INSTRUCTIONS FOR USE STATES: "THIS DEVICE IS USED WITH AN ELECTROSURGICAL UNIT FOR ENDOSCOPIC POLYPECTOMY." THE INSTRUCTIONS FOR USE ADVISE THE USER NOT TO USE THIS DEVICE FOR ANY PURPOSE OTHER THAN THE STATED INTENDED USE. USAGE OF THE ACUSNARE DEVICE WITHOUT AN ELECTROSURGICAL UNIT COULD HAVE CONTRIBUTED TO DIFFICULTY WITH SNARE RETRACTION. THE INSTRUCTIONS FOR USE DIRECT THE USER TO FULLY RETRACT AND EXTEND THE SNARE TO CONFIRM SMOOTH OPERATION OF THE DEVICE PRIOR TO USE. DIFFICULTY WITH MOVEMENT OF THE SNARE (I.E. SNARE ADVANCEMENT OR RETRACTION DIFFICULTY) CAN OCCUR IF SNARE DEVICE BECOMES DAMAGED DURING USE OR GENERAL HANDLING, PERHAPS DUE TO AN APPLICATION OF EXCESSIVE PRESSURE. THE INSTRUCTIONS FOR USE FOR THIS PRODUCT LINE ADVISE THE USER TO ADVANCE THE DEVICE IN SHORT INCREMENTS UNTIL ENDOSCOPICALLY VIEWED EXITING THE ENDOSCOPE. THIS ACTIVITY WILL AID IN PRESERVATION OF THE ACUSNARE DEVICE. PRIOR TO DISTRIBUTION, ALL ACUSNARE POLYPECTOMY SOFT SNARES ARE SUBJECTED TO A VISUAL INSPECTION AND FUNCTIONAL TEST TO ENSURE DEVICE INTEGRITY. THE VISUAL INSPECTION INCLUDES VERIFYING THE DEVICE IS FREE OF KINKS. THE FUNCTIONAL TEST ENSURES THE SNARE MOVES SMOOTHLY AND FREELY. A REVIEW OF THE DEVICE HISTORY RECORD CONFIRMED THAT THIS LOT MET MFG REQUIREMENTS PRIOR TO SHIPMENT. CORRECTIVE ACTION: NO CORRECTIVE ACTION WARRANTED AT THIS TIME BECAUSE THE INFO PROVIDED INDICATED THE PRODUCT WAS USED IN CONTRADICTION WITH THE INTENDED USE LISTED IN THE INSTRUCTIONS FOR USE AND THE REPORT WAS UNABLE TO BE VERIFIED. THE APPROPRIATE PERSONNEL HAVE BEEN INFORMED OF THIS OCCURRENCE IN AN EFFORT TO HEIGHTEN AWARENESS. THE COMPLAINT RISK PRIORITY NUMBER (CRPN) FOR THIS TYPE OF OCCURRENCE HAS BEEN CALCULATED BASED ON THE RATE OF OCCURRENCE AND SEVERITY OF THE OUTCOME. BASED ON THIS ACTIVITY, NO FURTHER ACTION IS WARRANTED AT THIS TIME. THE LIKELIHOOD OF THIS TYPE OF OCCURRENCE IS REMOTE. CUSTOMER QA WILL CONTINUE TO MONITOR FOR COMPLAINT TRENDS.
