Product code and device name: gca biliary catheter for stone removal that may also allow for irrigation and contrast injection.Investigation evaluation: our laboratory evaluation of the product said to be involved determined that there were portions of the balloon missing and all sections of the balloon did not match up under magnification.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 conclusion: 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 information provided indicated the balloon inflated properly prior to use.Therefore, the balloon was intact and functioning prior to advancement through the endoscope.A split or rupture in the balloon material can occur if the balloon has come into contact with a sharp object, such as a sharp stone, or possibly a burr in the endoscope channel.A split or rupture in the balloon material can also occur if added pressure was applied during extraction.The instructions for use direct the user to "gently withdraw the inflated balloon toward the papilla." the instructions for use contain the following: ¿warning: do not exert excessive pressure on ampulla while extracting stones.If stone does not pass easily, reassess need for sphincterotomy.¿ prior to distribution, all fusion quattro extraction 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: 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.

During an endoscopic retrograde cholangiopancreatography (ercp) procedure, the physician used a cook fusion quattro extraction balloon.It was initially reported that the balloon was pre-tested and worked as expected.The physician advanced balloon through an olympus 180 scope but when attempted to inflate it was noted that the balloon had burst.Another of the same device was used to complete the procedure.There was no reportable information at this time.Our evaluation of the returned device on 10/29/2021 determined that the balloon was ruptured and that there were portions of the balloon missing and all sections of the balloon did not match up.[subject of report] it was reported that a section of the device did not remain in the patient's body, but the location of the missing portion is unknown.Per the initial reporter, the patient did not require any additional procedures and didn't experience any adverse effects due to this occurrence.
