A visual, dimensional, and functional inspection was performed on the returned device.The reported inflation problem could not be confirmed; however, operational circumstances may have contributed.The reported bulky feeling (product quality problem) could not be confirmed.The reported difficult to remove could not be tested as it was based on operational context.A review of the production records and corrective or preventive actions (capa) was performed and revealed no indication of a product quality issue.Additionally, a query of the complaint handling database for the reported lot revealed no indication of a lot specific issue.The investigation determined the reported difficulties appear to be related to the operational context of the procedure.It was reported that the balloon dilation catheter (bdc) took longer than expected to deflate.A functional analysis was performed on the returned bdc.The bdc was inflated to rated burst pressure three times and the deflation time was measured.The deflation time was within specification.A bend on the hypotube was noted.A bend on the hypotube has the potential to limit contrast flow, possibly contributing to the reported deflation problem.It was also reported that the bdc encountered resistance during removal.It is possible that the balloon failed to fully deflate, due to the noted deflation problem.A not fully deflated balloon would impact the bdc¿s clearance with the guiding catheter, possibly resulting in the reported difficulty during removal.Additionally, a visual and dimensional examination was performed.No irregular appearance or anomalies were noted, it is unknown what contributed to the reported ¿bulky¿ feeling.There is no indication of a product quality issue with respect to manufacture, design, or labeling.D1 correction: brand name updated d2a correction: common device name updated d3 correction: name, address updated.
