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 staples in the staple cartridge are adapted to create an electrical potential within the tissue in the area of a wound or cut line. More specifically, the staples are arranged in spaced rings, wherein the staples in the spaced rings are formed of dissimilar metals having different anodic indexes to create a voltage gradient in the tissue to enhance cell migration toward the cut line.
