    Additional Manufacturer Narrative · 1

    EVALUATION: WE COULD NOT CONFIRM THE REPORT BECAUSE THE PRODUCT SAID TO BE INVOLVED WAS NOT RETURNED TO COOK ENDOSCOPY FOR EVAL. A REVIEW OF THE DEVICE HISTORY RECORD FOR THE PRODUCT SAID TO BE INVOLVED WAS CONDUCTED. DURING THE MFG PROCESS, (B)(4). THE APPROPRIATE PERSONNEL WERE INFORMED OF THIS OBSERVATION IN AN EFFORT TO HEIGHTEN AWARENESS. CUSTOMER QUALITY ASSURANCE WILL MONITOR FOR TRENDS. CONCLUSIONS: THE ADDITIONAL INFO PROVIDED INDICATED THE BALLOON DID NOT RECEIVE NEGATIVE PRESSURE PRIOR TO ADVANCEMENT THROUGH THE ENDOSCOPE. THIS IS THE MOST LIKELY CAUSE FOR THE REPORTED OBSERVATION. 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 MATERIAL RUPTURE 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. A BALLOON LEAK 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, SUCH AS A RUPTURE OR SPLIT. ANOTHER POSSIBLE CONTRIBUTING FACTOR IS USING 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 A RUPTURE OF 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 MFG REQUIREMENTS PRIOR TO SHIPMENT. CORRECTIVE ACTION: THE APPROPRIATE PERSONNEL HAVE BEEN INFORMED OF THIS TYPE OF OCCURRENCE IN AN EFFORT TO HEIGHTEN AWARENESS. NO FURTHER ACTION WARRANTED AT THIS TIME BECAUSE THIS REPORT COULD NOT BE VERIFIED AND THE INFO PROVIDED INDICATED THE PRODUCT WAS USED IN CONTRADICTION WITH THE INSTRUCTIONS FOR USE. CUSTOMER QUALITY ASSURANCE WILL CONTINUE TO MONITOR FOR COMPLAINT TRENDS.
