<p>An implantable prosthesis (20) for repairing or augmenting anatomical defects, including an inguinal hernia. The prosthesis includes a repair fabric having a body portion (22) and a support member (24) that may be arranged in or on the repair fabric to help deploy the repair fabric at the surgical site and/or help inhibit folding or buckling of the repair fabric. The support member may first and second ends (28, 30) that are spaced apart to form an interruption (32) so that a slit or keyhole arrangement may be formed in the repair fabric through the interruption and into an interior region of the body portion to receive a body structure. A portion of the support member may deviate inwardly toward the body portion to form an indentation (34) that is adapted to be positioned adjacent to a body structure, such as the femoral vessels. The indentation may be offset to one side of the prosthesis.</p>
