Abstract

A method of deploying a surgical fastener into a patient by introducing the fastener into a body of a patient while the fastener is in a first shape having a first loop with a back span and an original size and shape. The method then involves moving end segments of the fastener away from each other substantially along an entire length thereof while keeping the back span in substantially its original size and shape. The method then involves forming the fastener into a second loop having a width greater than a width of the first loop.
