Event Description

During an endoscopy procedure to dilate the esophagus, a cook hercules 3 stage wireguided balloon esophageal-pyloric-colonic was used.After the dilation was completed, the physician attempted to remove the device.When approximately half of the device was retracted into the endoscope channel, the physician felt a resistance as if balloon was caught by something.The physician applied more force, removed the device and found the balloon was ruptured.No section of the device detached inside the endoscope or patient.A section of the device did not remain inside the patient's body.The patient did not require any additional procedures due to this occurrence.According to the initial reporter, the patient did not experience any adverse effects due to this occurrence.

Manufacturer Narrative

Investigation evaluation: our evaluation of the returned device confirmed the report.There is a tear in the balloon approximately 3 cm from the distal end of the balloon.The balloon was attempted to be inflated with a 60 cc syringe and an inflation handle.The balloon was impossible to inflate.Water could be seen streaming from the tear.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 patient 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.According to the report lubrication was not applied to the balloon prior to advancement through the endoscope.A possible contributing factor to balloon material failure 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 allow easier passage through the accessory channel.This activity will aid in endoscopic advancement and balloon preservation.The instructions for use advise the user that negative pressure is needed 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 material failure 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 state, "maintain balloon deflation with negative pressure and introduce into the accessory channel of the endoscope, advancing in short increments until the dilator is completely visualized endoscopically.Monitor endoscopically until the balloon is in the desired position within the structure." the instructions for use contain the following warning: during dilation do not inflate balloon beyond the maximum indicated inflation pressure, as this could result in overextension or bursting of the balloon to achieve increasingly larger balloon diameters, increase pressure as indicated on the catheter tag.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 failure of the balloon material.Prior to distribution, all hercules 3 stage wireguided esophageal-pyloric-colonic balloons are subjected to a visual inspection and functional testing 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: 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.Additional comments regarding this report: based on the information provided, a cook representative has been directed to contact the medical facility involved in an effort to promote further education and understanding related to appropriate usage of this product.
