Event Description

During an esophageal dilation procedure, the physician used a cook hercules 3 stage wireguided balloon esophageal-pyloric-colonic.The balloon would not hold pressure when trying to dilate.They removed the balloon from the endoscope and saw that there was a hole in the balloon.They stopped the procedure at this time and it was not completed.

Manufacturer Narrative

On 9/8/2015, we became aware that the information provided in the other remarks section was not submitted on the initial emdr.Concomitant medical products: cook dilation syringe (ds-60cc-s).Investigation evaluation: our evaluation of the returned device confirmed the report.The balloon appears to be in the uninflated state when returned.There is a kink approximately.5 cm from the proximal balloon joint.The balloon was inflated with a 60cc syringe and an inflation handle.A small leak was observed at the distal balloon joint.The balloon would not hold pressure in this condition.No part of the device is missing.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 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.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 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.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 stricture." 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 balloon esophageal-pyloric-colonic 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: a review of the complaint history was conducted.The likelihood of occurrence is considered rare.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.
