Abstract:
1. An anchor unit implant for the repair of body tissue comprising: an anchor housing including a first peripheral wall and a second peripheral wall each including a sharp edge along an outer portion of the respective peripheral wall, the first peripheral wall and the second peripheral wall being laterally spaced from each other at a proximal end and converging into a sharp tip at a distal end such that the anchor housing is arranged in the shape of a knife blade; and an anchor blade assembly rotatably arranged with respect to the anchor housing and including a plurality of blades rigidly connected with a main shaft, the main shaft being rotatably arranged between the first and second peripheral walls of the anchor housing; wherein the anchor blade assembly is capable of being rotated with respect to the anchor housing from (i) a non-deployed state in which the plurality of blades are co-planar with the first and second peripheral walls of the anchor housing whereby the anchor unit implant can penetrate an area of body tissue to be repaired into (ii) a deployed state in which the plurality of blades extend beyond a plane defined by the first and second peripheral walls of the anchor housing and cut into body tissue to secure the anchor unit implant to the body tissue to be repaired; and wherein the anchor blade assembly is capable of being rotated with respect to the anchor housing from the deployed state back into the non-deployed state in which the plurality of blades are co-planar with the first and second peripheral walls of the anchor housing and the anchor unit implant is then removable from the area of body tissue to be repaired and re-positionable.
