Abstract
An anchoring member comprises a support structure and at least one anchor secured to the anchoring member. An anchor deflection member supports the anchoring member for sliding longitudinal movement in directions which result in advancement and retraction of a point on the anchor. A deflection lip is positioned relatively inwardly with respect to the guide surface. The deflection lip is positioned to outwardly deflect the point of the anchor as the anchor is advanced from a position removed from the deflection lip toward the deflection lip into contact with the deflection lip and beyond the deflection lip.
