Abstract

An apparatus for implanting an element within a tissue a cannula having a sharpened tip at a beveled distal end, and a stylet. The stylet is configured to engage the element within a hollow bore of the cannula, so that the element is pushed through the hollow bore out of the beveled distal end onto the tissue, when the cannula is moved relative to the stylet along an axis. A bevel-shaped insert member has a bevel angle that matches the bevel angle of the cannula distal end. The outer surface of the insert member supports the tissue, to prevent the tissue from prolapsing into the interior of the beveled distal end during penetration of the tissue by the sharpened tip. A protruding structure extends from the outer surface of the member, and frictionally holds the member in place along the interior surface of the hollow bore during the penetration.
