Investigation evaluation: our laboratory evaluation of the products said to be involved confirmed the report as it was described.Two (2) devices were returned along with their syringes that were packaged with the devices.During the evaluation of the first device, the syringe was filled with air and inflated.The balloon filled with air as intended.When it was time to deflate the device, the black rubber piece on the plunger of the syringe was stuck when pressed against the distal end of the syringe.There appeared to be some kind of substance in the syringe that could have prevented the syringe from performing as intended.The substance had a very greasy feeling to it.The syringe handle was pulled back on and the balloon deflated.During evaluation of the second device, the syringe was filled with air and was attached to the inflation port.The balloon filled and deflated as intended.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.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.

In preparation for an endoscopic procedure, the physician selected two (2) cook fusion quattro extraction balloons, they were prepping the devices and having issues with the inflation syringe sticking.This caused the balloons not to deflate.This occurred with two devices of same lot in one case.The devices did not make patient contact.
