1. A kit for treating tissue of a subject, the kit comprising:
a tool for creating a wedge opening within a bone tissue, comprising:
an outer member comprising a first end and a second end, a cylindrical interior extending from the first end to the second end and having openings at the first and second ends, the first end comprising a tapered portion configured to be inserted within a cylinder-shaped opening created within the bone tissue;
a cutting member comprising an inner passage, positioned within the cylindrical interior of the outer member near the first end of the outer member and coupled to the outer member, the cutting member comprising at least one cutter configured to be radially expanded outward; and
an inner member configured to be moved within the inner passage of the cutting member, wherein when the inner member is moved within the inner passage of the cutting member, the at least one cutter is configured to radially expand,
wherein the at least one cutter is configured to radially expand at an angle relative to a longitudinal axis of the tool so as to create the wedge opening within the bone tissue when the at least one cutter is expanded and rotated relative to said tissue; and
an implant configured to be inserted and secured within the wedge opening created by the tool.
