Subcutaneous self attaching injection port with integral fasteners

摘要

A self attaching injection port (18) has integral fasteners (28) extending from the housing (20), fixed relative thereto. The fasteners include one way fasteners, such as formed by a plurality of axially spaced concentrically aligned frustroconical annular flanges (32). The injection port is self attaching upon the surgeon applying a distal force to the injection port housing, causing the fasteners to penetrate the tissue, engaging the tissue to hold the injection port in place.
