Abstract:
A medical anchor for emplacement in a borehole in biological tissue, the anchor comprising:a central portion;at least one outer portion attached to the central portion, the outer portion having a cutting edge;the anchor being adapted to be inserted in the borehole in approximate alignment with a longitudinal axis of the borehole, and further being adapted to be rotated in two axes to secure the anchor in the borehole, a first axis of rotation being aligned with the axis of the borehole and a second axis of rotation being perpendicular to the axis of the borehole, further comprising a cam surface on said anchor for engagement by a pushing member for causing said anchor to rotate about the second axis, whereby the anchor moves outwardly about the second axis so that the cutting edge cuts into a wall of the borehole and the anchor is rotated about the first axis to achieve a final position substantially perpendicular to the borehole.
