    Additional Manufacturer Narrative · 1

    EVALUATION: OUR LABORATORY EVALUATION OF THE PRODUCT SAID TO BE INVOLVED CONFIRMED THE REPORT. THE DAMAGED AREA IS LOCATED NEAR THE PROXIMAL END OF THE DILATION BALLOON. THE APPEARANCE OF THE DAMAGED AREA SUGGESTS THE BALLOON CAME INTO CONTACT WITH A SHARP OBJECT, PERHAPS A SHARP EDGE OF THE ENDOSCOPE USED WITH THIS BALLOON DILATOR. THE CATHETER TUBING DOES NOT EXHIBIT ANY STRETCHED OR DAMAGED AREAS. DURING A FUNCTIONAL EVALUATION, A COOK QUANTUM INFLATION DEVICE FILLED WITH WATER WAS USED IN AN ATTEMPT TO INFLATE THE BALLOON. WHEN THE BALLOON IS INFLATED WITH WATER, WATER EXITS THE BALLOON MATERIAL AT THE LOCATION OF THE DAMAGED AREA. THE BALLOON WILL NOT HOLD PRESSURE AND CANNOT PERFORM DILATION IN THIS CONDITION. A MANUFACTURING DISCREPANCY OR ANOMALY THAT COULD HAVE CONTRIBUTED TO THIS REPORT WAS NOT OBSERVED DURING OUR LABORATORY EVALUATION. A REVIEW OF THE DEVICE HISTORY RECORD CONFIRMED THAT THE LOT SAID TO BE INVOLVED MET ALL MANUFACTURING REQUIREMENTS PRIOR TO SHIPMENT. A REVIEW OF THE TWELVE MONTH COMPLAINT HISTORY FOR THIS PRODUCT FAMILY WAS CONDUCTED. CONCLUSION: A POSSIBLE CONTRIBUTING FACTOR TO BALLOON MATERIAL 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. ANOTHER POSSIBLE CONTRIBUTING FACTOR TO BALLOON MATERIAL DAMAGE IS FAILURE TO APPLY NEGATIVE PRESSURE TO THE BALLOON DILATOR PRIOR TO ADVANCEMENT THROUGH THE ENDOSCOPE. 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. 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 COMPLETE 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.
