Abstract
Anchoring elements of a fastener are made elastically curved. The curvatures of the elements are resiliently straightened by a trocar for tissue insertion. As the trocar is withdrawn, the anchoring elements resume the curved configuration, laterally pressing the elements against tissue to anchor the fastener.
