ABSTRACT:
A fastening system device having dimensions of very small magnitudes for attaching a mesh prosthesis or tissue to body tissue. The device has a shaft member which has a continuous outer peripheral surface and so constructed such that the outer surface is a continuous surface and has a continuous curved cross-section where the center of curvature is in the radial direction of the longitudinal axis; the shaft has sufficient columnar resistance to bending to permit the shaft member to penetrate body tissue. A head member extends radially from the shaft member at a second end and is so dimensioned and proportioned to form a bearing surface for bearing against the mesh prosthesis. A resiliently collapsible anchor member is integrally fixed to the first end of the shaft and separately forms a conical distal tip. The anchor member extends proximately and is contained at least in part in the conical surface of the conical tip and projects angularly with respect to the outer continuous peripheral surface and is bounded in radial collapsibility by the continuous outer peripheral surface of the shaft.
