Abstract
A tissue connector has a first pointed end, an anchor end, a body with a periphery and a plurality of barbs projecting from said periphery of said body. The plurality of barbs are yieldable in one direction, which direction is the direction of motion of the first pointed end through tissue, and are rigid in an opposite direction, which is in the direction of the anchor end. At axial locations of said body, said barbs are about equally located about the periphery of said body. At axial locations on a cylindrical periphery of the body barbs are locate at about 120 degree spacings. The barbs are conically shaped.
