Abstract: A staple cartridge is adapted to enhance cell migration towards a wound site when staples are placed in tissue. In order to enhance cell migration, the staple cartridge is adapted to create an electrical potential within the tissue in the area of a wound or cut line. In embodiments, the electrical potential is created within the tissue by using staples in spaced rows formed of dissimilar metals having different anodic indexes to create a voltage gradient in the tissue to enhance cell migration toward the cut line.
