(b)(4).Additional information: a leak in the band has been confirmed utilizing contrast; however, the doctor could not tell specifically where the leak was originating as it was not a ct scan.They plan to remove the band and will be providing the band for analysis.Components were returned as follows: the port, engraved with lot number zpgbb9.Biological debris was evident on the port.The band/balloon, engraved with lot number zpgbbz, with approx.42 cm of catheter attached.The band was returned without the buckle.The locking connector and tubing strain relief were returned detached from the device.Leak testing was performed on the band/balloon and no air bubbles were visible.No leak on the band/balloon was evident.Leakage was observed on the end of the catheter where the catheter connects to the hose of the port.No leakage was observed on the balloon or port.Upon visual inspection, two tears were evident on the catheter, however no leak was identified.It is suggested that the damage may have been caused by a sharp instrument.Perforations were evident on the tubing strain relief - this is likely due to needle puncture.It is noted that the measurements of the perforation areas on the catheter end and the tubing strain relief do not align.It is also noted that if the locking connector was correctly secured in the locked position the perforation areas on the catheter end would not have been easily accessible.Root cause is difficult to assign.The port septum was examined under microscopic view, and 11 punctures were evident on the septum.This suggests that several adjustments were performed.A device history record review was performed and no anomalies were found with respect to the manufacturing process.It was also noted that products are 100% inspected prior to distribution therefore a manufacturing issue is unlikely to have contributed to the event.
