    EVALUATION: A PRODUCT EVALUATION WAS NOT PERFORMED IN RESPONSE TO THIS REPORT BECAUSE THE PRODUCT SAID TO BE INVOLVED WAS NOT PROVIDED TO COOK FOR EVALUATION. THE REPORT COULD NOT BE CONFIRMED. A REVIEW OF THE DEVICE HISTORY RECORD AND SAMPLE TEST FROM THIS LOT COULD NOT BE CONDUCTED BECAUSE THE LOT NUMBER WAS NOT PROVIDED. AFTER A REVIEW OF THE ACCOUNT ORDERING AND SHIPPING HISTORY, THE LOT NUMBER INVOLVED COULD NOT BE DETERMINED. CONCLUSION: WE ARE UNABLE TO DETERMINE A CAUSE FOR THE REPORT BECAUSE THE PRODUCT COULD NOT BE EVALUATED. THE INSTRUCTIONS FOR USE DIRECT THE USER TO APPLY NEGATIVE PRESSURE TO THE CATHETER TO FACILITATE PASSAGE THROUGH THE ENDOSCOPE. THE APPLICATION OF NEGATIVE PRESSURE WILL ASPIRATE ALL RESIDUAL AIR FROM THE BALLOON AND EASE ENDOSCOPIC ADVANCEMENT. NEGATIVE PRESSURE WILL ALSO AID IN BALLOON PRESERVATION AND OPTIMIZE BALLOON PERFORMANCE. A POSSIBLE CONTRIBUTING FACTOR TO BALLOON DAMAGE IS INADEQUATE LUBRICATION OF THE BALLOON WITH A LUBRICATING AGENT. THE INSTRUCTIONS FOR USE DIRECT THE USER TO APPLY A LUBRICATING AGENT TO THE BALLOON TO FACILITATE PASSAGE THROUGH THE ENDOSCOPE ACCESSORY CHANNEL. THIS ACTIVITY WILL AID IN ENDOSCOPIC ADVANCEMENT AND BALLOON PRESERVATION. DAMAGE TO THE BALLOON MATERIAL CAN OCCUR IF THE BALLOON IS INFLATED PRIOR TO ADVANCEMENT THROUGH THE ENDOSCOPE OR IF THE BALLOON IS INFLATED WHILE PARTIALLY OR FULLY INSIDE THE ACCESSORY CHANNEL OF THE ENDOSCOPE. THE INSTRUCTIONS FOR USE CONTAIN THE FOLLOWING PRECAUTION: "DO NOT PRE-INFLATE THE BALLOON." THE INSTRUCTIONS FOR USE DIRECT THE USER TO ENSURE THE BALLOON IS COMPLETELY VISUALIZED AND POSITIONED BEFORE INFLATION. THE INSTRUCTIONS FOR USE CONTAIN THE FOLLOWING WARNING: "DURING DILATION, DO NOT INFLATE BALLOON BEYOND THE MAXIMUM INDICATED INFLATION PRESSURE." OVER INFLATION CAN CAUSE DAMAGE TO THE BALLOON DILATOR. ANOTHER POSSIBLE CONTRIBUTING FACTOR IS USING A COMPROMISED INFLATION DEVICE TO INFLATE THE BALLOON. IF THE PRESSURE READING OF THE INFLATION DEVICE IS INACCURATE, THIS COULD CONTRIBUTE TO OVER INFLATION, POSSIBLY RESULTING IN DAMAGE TO THE BALLOON MATERIAL. PRIOR TO DISTRIBUTION, ALL HERCULES 3 STAGE ESOPHAGEAL BALLOON DILATORS ARE SUBJECTED TO A VISUAL EXAMINATION 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: A CORRECTIVE ACTION HAS BEEN INITIATED IN AN EFFORT TO REDUCE OCCURRENCES OF THIS NATURE. THIS PRODUCT WAS MANUFACTURED PRIOR TO IMPLEMENTATION OF THIS CORRECTIVE ACTION. CUSTOMER QUALITY ASSURANCE WILL CONTINUE TO MONITOR FOR COMPLAINT TRENDS.
