A tissue anchor includes a generally flexible elongate continuous anchor member capable of being inserted through tissue and moving between an elongate configuration and a shortened configuration suitable for anchoring against at least one side of the tissue. The anchor member has a first set of openings and a second set of openings formed therein at spaced locations along a length of the anchor member. The tissue anchor also includes a tensioning member operatively connected to the anchor member and the tensioning member extends through the proximal end portion to the distal end portion by passing through the first set of openings and then back to the proximal end portion by passing through the second set of openings. The anchor member is configured to form a plurality of folded panels upon pulling the tensioning member. The plurality of folded panels comprises a set of first panels that are oriented in a first direction and at least one second panel that is oriented in a second direction that is perpendicular to the folded set of first panels.
