A curved surgical fastener for anchoring medical devices to tissue includes a curved member having a proximal end, a distal end, and a tissue penetrating end at the distal end of the curved member. The curved member has a total curvature of less than 360 degrees between the proximal and distal ends. The proximal end of the curved member lies in a first plane, the distal end of the curved member lies in a second plane that is offset from the first plane, and the curved member has an intermediate section that extends between the first and second planes. The curved member includes a compound curve having a proximal section with a first radius of curvature and a distal section with a second radius of curvature that is different than the first radius of curvature.
