ABSTRACT:
The invention is a sternal retractor comprising a curved crossbar and a pair of arms perpendicularly attached to the crossbar, at least one of which may slide over the length of the crossbar. Sternum engaging blades extend from the arms in a general direction from the concave side to the convex side of the retractor. The present invention lifts the ribcage, allowing access to the internal mammary artery while decreasing tissue damage associated with current retractors.
