US Patent 7021316 Device and method for tacking a prosthetic screen

A prosthetic screen tacking device includes a barbed filament with a perpendicular foot at one end and a loop at the other. The barbs are situated near the foot and angulated in such a manner that they permit movement of the device through tissue in one direction (toward the loop), but prevent movement in the opposite direction (toward the foot). Different barbs and feet are shown. Methods of using the device with or without an associated button are also disclosed.
