Subcutaneous self attaching injection port with integral fasteners

摘要

A self attaching injection port has integral fasteners extending from the housing, fixed relative thereto. The fasteners include one way fasteners, such as formed by a plurality of axially spaced concentrically aligned frustroconical annular flanges. 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.
