Anchor and anchor installation tool and method

摘要

Apparatus for inserting an anchor into a bore in a medium, the anchor being adapted to engage the walls of the bore for securing the anchor into the medium. The bore is sized slightly larger than the outside diameter of the anchor in its undeployed condition. The apparatus includes a first manually graspable member having a distal end and a proximal end, the distal end being adapted to releasably receive the anchor. The manually graspable member has a central opening therethrough, the proximal end of the manually graspable member having a pivotable handle extending therefrom. A second member is movable longitudinally in the central opening and is attached to the pivotable handle and to the anchor. A release member couples the anchor to the second member. The pivotable handle is pivotable with respect to the first member and exerts a force longitudinally on the second member to move the second member longitudinally in the first member. This movement exerts a force on the anchor connected thereto to deform the anchor to cause the anchor to engage the walls of the medium thereby to secure the anchor in the medium. The force exerted on the second member further acts on the release member to separate the anchor from the second member when the anchor has deformed to engage the walls of the bore.
