Toggle anchor and tool for insertion thereof

A method for delivering an anchor member into biological tissue comprising: accessing and preparing an insertion site for the anchor member; holding the anchor member at a distal end of an insertion tool; providing the anchor member to the site with the insertion tool; causing a rotational movement of the anchor member about a first axis perpendicular to a longitudinal axis of the insertion tool whereby the anchor member engages the tissue at the site by moving about the first axis from a first position substantially aligned with the longitudinal axis to a second position at an angle relative to the longitudinal axis; and withdrawing the insertion tool from the site, leaving the anchor member secured at the site.
