Claim:
1. A surgical implant for implementing a ligament reconstruction in a subject using a first ligament and a second ligament, the implant comprising: a sheath extending from a first end along a length to a second end to form an exterior surface and an interior surface, wherein the interior surface forms a lumen, the sheath including an end surface between the exterior surface and the interior surface; a first ledge formed on the exterior surface of the sheath and extending along the length of the sheath; a second ledge formed on the exterior surface of the sheath in a spaced relationship to the first ledge; a first anchor formed on the exterior surface of the sheath and extending along the length of the sheath; a second anchor formed on the exterior surface of the sheath and extending along the length of the sheath; the first anchor positioned between the first ledge and the second ledge on a first side of the sheath, and the second anchor positioned between the first ledge and the second ledge on a second side of the sheath, the first side being 180 degrees about a circumference of the sheath from the second side; a sheath expander configured to selectively extend and retract to and from the lumen of the sheath; wherein the spaced relationship of the first ledge and the second ledge are configured to cooperate with the sheath to form a barrier separating the first ligament and the second ligament when the implant is implanted in the joint of the subject; wherein the first anchor and the second anchor are configured to move between a first position to a second position in response to the sheath expander extending through the lumen of the sheath to thereby engage the first anchor with the first ligament and second anchor with the second ligament, the first position being a concave position and the second position being a convex position; and wherein the end surface of the sheath has a perimeter, the perimeter of the end surface of the sheath remains continuous when the sheath expander has been inserted completely into the lumen of the sheath thereby defining an uninterrupted end.
