US Patent 8409221 Implantable access port device having a safety cap

A system for attaching an access port to bodily tissue includes an access port assembly and including an access port having a generally central axis. The access port assembly further includes an attachment mechanism structured to enable the access port to be attached, for example, to an abdominal muscle of a patient. The system includes a safety cap which lies substantially flush against the anchor base to provide no space for movement of the anchors. The safety cap prevents the anchors from deploying prematurely.
