Abstract
An anchor includes an anchor body configured to be retained within base tissue. The anchor body includes a unidirectional mechanism to selectively restrict passage of a flexible member through the anchor. The flexible member includes a loop to enable attachment of candidate tissue to base tissue without the use of knots.
