Abstract
An access platform having a first and a second blade interconnected to a spreader member that laterally drives the blades apart or together and support pads interconnected to the first blade. A torsional member is operably interconnected to the first blade and the spreader member and is used to vertically displace the first blade in either direction and, thus, increase a surgeon's working space and visual access for the dissection of an internal mammary artery. A tissue retractor interconnected to the blades is used to draw the soft tissue around an incision away from the surgeon's working area.
