Devices and methods for creating wedge-shaped recesses
First Claim
1. A tool configured to make a wedge-shaped recess within a bone along or near a joint of a patient, comprising:
- a main body comprising a proximal end and a distal end;
wherein the proximal end of the main body is configured to be selectively rotated;
a flange located along the distal end of the main body; and
at least one articulating cutter extending distally from the flange, said at least one articulating cutter configured to be selectively moved between a stowed position and a radially extended position;
wherein the at least one articulating cutter is configured to be angled relative to a longitudinal axis of the tool when in the radially extended position; and
wherein the at least one articulating cutter is configured to create a wedge-shaped recess within a bone when in the radially extended position, wherein a diameter of a bottom opening of the recess is larger than a diameter of a surface opening of the recess.

Abstract
According to some embodiments, a method of treating a joint of a patient comprises creating a recess in a bone located at or near a targeted joint, wherein the recess includes a generally wedge or truncated cone shape. In one embodiment, the recess in a bone comprises a surface opening along an outer surface of the bone and a bottom opening along the distal end of the recess, such that a diameter of the surface opening is generally smaller than a diameter of the bottom opening. The method additionally comprises providing a joint implant having a wedge or truncated cone shape, wherein a diameter of a top end of the joint implant is generally smaller than a diameter of a bottom end of the joint implant, inserting the joint implant within the recess.
