Abstract
A surgical fastener is provided for various surgical fastening applications, including attaching an implantable prosthesis, such as a soft tissue repair fabric, to tissue and/or muscle. The surgical fastener may include a coil body and a separate head that is attached to the coil body. The head may include an internal thread that is threadably attached to the coil body. The head may also be further secured to the coil body with a compression fit therebetween. A locking feature may prevent back-out of the coil body from the head. The surgical fastener may be assembled by threading the coil body through the head.
