Device evaluation summary: the device was returned to apollo, and a visual inspection was performed.The band ring and shell were noted to be discolored, as they were light brown in appearance.White particulate matter was observed on the inner and outer surfaces of the band shell, and on the outer surface of the band ring.The taper tubing was present on the separated piece of port tubing.The end of the separated piece of port tubing was separated approximately 1.25 inches from the taper tubing junction.Under microscopic analysis, both ends of the separated port tubing were noted to have striated edges, consistent with a surgical end cut to remove the device.Needle marks were observed on the port septum.One black particle was noted at the edge of the port septum.Non-penetrating nicks/marks were noted on the port housing near the septum.An air leak test was performed, and leakage was noted from the band shell where the band had been separated near the buckle.A fill inspection test was performed, and no blockage was noted when di water was passed through the port septum, or through the port tubing.Under microscopic analysis, the band was separated in half approximately 0.9 inches from the buckle.Both ends of the separated band ring and shell were observed to have striated edges, consistent with damage from a surgical tool.
