Abstract
Implementations of the present disclosure provide a fastener including a tip portion, a proximal portion, an advancement mechanism and an expandable member. The tip portion has a first surface. The proximal portion is configured for coupling to the tip portion and has a second surface. The mechanism advances the first surface toward the second surface. The expandable member includes a first end abutting the first surface of the tip portion and a second end abutting the second surface of the proximal portion. Advancement of the two surfaces toward each other advances the first end of the expandable member toward the second end of the expandable member. The expandable member is configured to expand in response to the advancement. At least one of the ends of the expandable member is a free end extending under and configured to rotate with respect to an abutting one of the first or second surfaces.
