    INVESTIGATION EVALUATION: OUR EVALUATION OF THE RETURNED PRODUCT CONFIRMED THE REPORT. THERE WAS A SPLIT ALONG THE LENGTH OF THE BALLOON. THE BALLOON WOULD NOT HOLD FLUID AND COULD NOT BE INFLATED. A PRODUCT-SPECIFIC DISCREPANCY THAT COULD HAVE CAUSED OR CONTRIBUTED TO THIS OBSERVATION WAS NOT OBSERVED DURING OUR LABORATORY ANALYSIS. THE DEVICE HISTORY RECORD FOR THE LOT NUMBER SAID TO BE INVOLVED WAS REVIEWED. A DISCREPANCY OR ANOMALY WAS NOT OBSERVED WITH THE PRODUCT THAT WAS RELEASED FOR DISTRIBUTION. INVESTIGATION CONCLUSIONS: A DEFINITIVE CAUSE FOR THIS OBSERVATION COULD NOT BE DETERMINED BECAUSE THE ACTUAL USE CONDITIONS COULD NOT BE DUPLICATED IN THE LABORATORY SETTING. DUE TO A VARIETY OF CLINICAL CONDITIONS SUCH AS PT ANATOMY, ENDOSCOPE POSITION OR PROGRESSION OF DISEASE STATE, WE COULD NOT REPRODUCE THE ACTUAL CONDITIONS OF PRODUCT USAGE DURING OUR LABORATORY ANALYSIS. THIS LIMITS OUR ABILITY TO CONCLUSIVELY DETERMINE A CAUSE. A POSSIBLE CONTRIBUTING FACTOR TO BALLOON MATERIAL RUPTURE 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 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 BALLOON RUPTURE 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 ALSO CONTAIN THE FOLLOWING PRECAUTION: "THE ENTIRE QUANTUM TTC ESOPHAGEAL BALLOON DILATORS SHOULD BE EXTENDED BEYOND THE TIP OF THE ENDOSCOPE AND BE COMPLETELY VISUALIZED AND POSITIONED BEFORE INFLATION." THE INSTRUCTIONS FOR USE CONTAIN THE FOLLOWING WARNING, "THE RECOMMENDED 100% BALLOON INFLATION PRESSURE CAN BE FOUND ON THE QID - QUANTUM INFLATION DEVICE AND ON THE SHRINK TUBE OF THE QUANTUM TTC BALLOON DILATORS." OVER INFLATION CAN CAUSE DAMAGE TO THE BALLOON DILATOR, SUCH AS A RUPTURE OR SPLIT. 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 A RUPTURE OF THE BALLOON MATERIAL. PRIOR TO DISTRIBUTION, ALL QUANTUM TTC ESOPHAGEAL BALLOON DILATORS ARE SUBJECTED TO A VISUAL INSPECTION AND FUNCTIONAL TESTING TO ENSURE DEVICE INTEGRITY. CORRECTIVE ACTION: CORRECTIVE ACTION IS NOT WARRANTED AT THIS TIME BASED ON THE QUALITY ENGINEERING RISK ASSESSMENT. QUALITY ASSURANCE WILL CONTINUE TO MONITOR FOR COMPLAINT TRENDS AND REASSESS THE RISK ASSESSMENT RESULTS AS POST MARKET FEEDBACK CONTINUES TO BECOME AVAILABLE.

    Description of Event or Problem · 1

    A COOK QUANTUM TTC ESOPHAGEAL BALLOON DILATOR WAS USED DURING A PROCEDURE TO DILATE THE ESOPHAGUS. THE BALLOON WAS ADVANCED THROUGH THE ENDOSCOPE AND INFLATED WITH WATER. DURING THE INITIAL INFLATION OF THE BALLOON, IT BURST. THE PHYSICIAN USED ANOTHER OF THE SAME DEVICE TO COMPLETE THE PROCEDURE. A SECTION OF THE DEVICE DID NOT REMAIN INSIDE THE PT'S BODY. THE PT DID NOT REQUIRE ANY ADDITIONAL PROCEDURES DUE TO THIS OCCURRENCE. ACCORDING TO THE INITIAL REPORTER, THE PT DID NOT EXPERIENCE ANY ADVERSE EFFECTS DUE TO THIS OCCURRENCE.
