Concomitant medical products: boston scientific alliance inflation handle, olympus visiglide 0.035 inch wire guide.Investigation evaluation: our laboratory evaluation of the product said to be involved confirmed the report.As per the image provided by the customer, a visual inspection of the device returned confirmed a pinhole is present near the proximal end of the balloon.During a functional test, a cook quantum biliary inflation device (qbid) syringe filled with water was attached to the inflation port of the biliary dilation device.While inflating the balloon, a pinhole leak near the proximal end of the balloon material was observed.No section of the balloon was missing.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.A discrepancy or anomaly that could have contributed to the reported observation was not observed during our laboratory analysis of the returned product.The instructions for use under the intended use of the device states: "this device is used to dilate strictures of the biliary tree".A balloon material pinhole can occur if inadequate lubricant is applied prior to advancement through the endoscope.This is the most likely cause for the reported observation.The instructions for use direct the user to: "apply a water-soluble lubricant to balloon to allow easier passage through accessory channel".This activity will aid in endoscopic advancement and balloon preservation.A balloon material pinhole can occur if inadequate negative pressure is applied.The instructions for use direct the user to "create and maintain a vacuum with inflation device.Dilation balloon is now ready for placement through accessory channel of duodenoscope." 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 pinhole 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 inflate the balloon prior to introduction into the scope.¿ the instructions for use also contain the following precaution: ¿the entire dilation balloon must be extended beyond the tip of the duodenoscope and be fluoroscopically visualized and positioned before inflation.¿ prior to distribution, all fusion biliary dilation balloons are subjected to a visual inspection and functional test to ensure device integrity.During this test, the outer diameter vs.Pressure is measured and verified.During the final quality control (fqc) inspection, all devices are inflated to check for leakage 100%.The outer diameter of the balloon is measured 100% during inflation.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 that the device was used to dilate the papilla (off-label use), 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.

During an endoscopic papillary balloon dilation (epbd) procedure, the physician used a cook fusion biliary dilation balloon.The user inserted a fusion biliary dilation balloon into the papilla and applied pressure, but the balloon would not inflate to the desired size.It was replaced with another manufacturer's balloon catheter to complete the procedure.A picture of the balloon was provided on 11/16/2016.This picture shows a pinhole in the balloon, implying leakage of the device.
