Each prong of the fastener has a protuberance at one end that is received in a depression around an edge of the first element and rotatable in the depression and has a tip at a second end. In an undeployed configuration, each prong passes through a slot of the second element and the tip of each prong is at a first distance from the axis. In a deployed configuration, each prong passes through the prong's slot of the second element, and the tip of each prong is at a second distance from the axis that is greater than the first distance. The invention also provides a system for surgical fastening including one or more surgical fasteners of the invention and a surgical fastening device configured to deploy the fasteners.
