    EVAL: A PRODUCT EVAL WAS NOT PERFORMED IN RESPONSE TO THIS REPORT BECAUSE THE PRODUCT SAID TO BE INVOLVED WAS NOT PROVIDED TO COOK FOR EVAL. 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. 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 CAUTION THE USER THAT NEGATIVE PRESSURE IS MANDATORY TO MAINTAIN BALLOON DEFLATION. 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 DAMAGE IS INADEQUATE LUBRICATION OF THE BALLOON WITH A WATER SOLUBLE LUBRICANT. THE INSTRUCTIONS FOR USE DIRECT THE USER TO APPLY A WATER SOLUBLE LUBRICANT TO THE BALLOON TO ALLOW EASIER PASSAGE THROUGH THE ACCESSORY CHANNEL. THIS ACTIVITY WILL AID IN ENDOSCOPIC ADVANCEMENT AND BALLOON PRESERVATION. 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 QUANTUM TTC ESOPHAGEAL BALLOON DILATORS ARE SUBJECTED TO A TEST THAT MEASURES THE OUTER DIAMETER AND PRESSURE. CORRECTIVE ACTION: BASED ON THE QUALITY ENGINEERING RISK ASSESSMENT, NO CORRECTIVE ACTION IS WARRANTED AT THIS TIME. QUALITY ASSURANCE WILL CONTINUE TO MONITOR FOR COMPLAINT TRENDS.
