Manufacturer Narrative

Concomitant medical products: (b)(4) inflation handle, syringe (unknown type). For the one (1) reported event, the device was not returned to cook endoscopy and the operating condition was unable to be confirmed. A product evaluation was not performed in response to this report because the product said to be involved was not provided to cook for evaluation. The report could not be confirmed. 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. We could not conduct a complete investigation because the product said to be involved was not returned for evaluation. A definitive cause for the reported observation could not be determined. According to the report lubrication and negative pressure were 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 facilitate passage through the endoscope accessory channel. " this activity will aid in endoscopic advancement and balloon and catheter 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 and catheter 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 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. The instructions for use state: "to achieve increasingly larger balloon diameters, increase pressure as indicated on 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 balloon esophageal are subjected to a visual inspection and functional testing to ensure device integrity. 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. 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.

 
Event Description

This report summarizes one (1) malfunction event. A review of the event indicated that when inflating the cook hercules 3 stage balloon during an esophageal dilation procedure, the balloon popped. The physician had to remove the endoscope containing the balloon for removal. Another device was used to complete the procedure. The event involved a patient with no patient consequences.
