Visual analysis was performed on the returned device.The reported balloon rupture and separation were confirmed.The reported difficulty removing the device could not be replicated in a testing environment as it was based on operational circumstances.The electronic lot history record (elhr) and corrective and preventive actions (capa) reviews were performed and revealed no indication of a product quality issue.Additionally, a query of the complaint handling database for the reported lot revealed no other similar complaints from this lot.The investigation determined the reported balloon rupture, difficulty removing the device from the anatomy, balloon separation and surgical intervention appear to be related to operational context.Balloon material ruptures can be affected by numerous factors including, but not limited to, balloon damage during processing of the balloon material, materials, inflation technique, and interactions with other devices or lesion calcification.In this case, it is likely that the balloon interacted with the heavily calcified anatomy such that the balloon became damaged and ruptured during inflation.Additionally, during removal there was resistance as the ruptured balloon material likely interacted with the patient challenging anatomy causing the balloon material to separate.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.
