In one aspect, the dual bevel needle can include a hollow tube having a proximal end, a distal end, a first lateral side, and a second lateral side opposite the first lateral side； a first needle point at the distal end of the hollow tube； a second point at the distal end of the hollow tube； a first bevel on each of the first lateral side and the second lateral side, the first bevel comprising a first bevel angle relative to a longitudinal axis of the tube； and a second bevel on each of the first lateral side and the second lateral side, the second bevel having a second bevel angle relative to the longitudinal axis of the tube, wherein the first and second bevels each form a portion of an ellipse, the ellipse having an inner cutting edge and terminating in the first and second needle points at the distal end of the tube, the second bevel angle being shallower than the first bevel angle, the second bevel being located adjacent the proximal end of the first bevel, and the inner cutting edge converging to a narrow heel.
