1. A method for reattaching a soft tissue to bone at a natural footprint of the soft tissue on the bone, comprising:
- providing at least one directional anchor having a soft tissue anchoring section and a bone anchoring section;
inserting the at least one directional anchor into the surface of bone so that the bone anchoring section penetrates the bone surface and the soft tissue anchoring section extends away from the bone;
placing soft tissue over the soft tissue anchoring section so that the soft tissue anchoring section penetrates only one surface of the soft tissue; and
applying force onto the soft tissue so that the soft tissue anchoring section extends into the soft tissue and enhances the mating engagement of the soft tissue to the bone, wherein the mating engagement is at the natural footprint of the soft tissue on the bone.

Abstract
Disclosed herein are devices and methods for securing soft tissue to a rigid structure such as bone. Various directional anchors that allow for increasing the stability the attachment of soft tissue to bone are described. Also described is a delivery system for use with the directional anchors that allows for open surgical or arthroscopic application of one embodiment of the device. A method for repairing rotator cuff tears is also described.

13. A method for reattaching a tissue to bone, comprising:
-
providing a first directional anchor, a second directional anchor, up to an Nth directional anchor, the directional anchors having a tissue anchoring section and a bone anchoring section; preparing the surface of the bone by abrading a cortical surface of the bone; inserting the directional anchors into the prepared cortical surface of bone so that the bone anchoring sections penetrate the prepared cortical bone surface and the tissue anchoring sections extend away from the bone; placing tissue over the tissue anchoring sections so that the tissue anchoring sections penetrate only one surface of the tissue; and applying force onto the tissue so that the tissue anchoring sections extend into the tissue thereby enhancing the mating engagement of the tissue to the bone. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)

21. A method for attaching tissue to bone, comprising:
-
providing a plurality of directional anchors each having a tissue anchoring section and a bone anchoring section; preparing the surface of the bone by abrading a cortical surface of the bone; inserting the directional anchors into the prepared cortical surface of bone so that the bone anchoring sections penetrate the prepared cortical surface of the bone and the tissue anchoring sections penetrate tissue; placing tissue over the tissue anchoring sections so that the tissue anchoring sections penetrate only one surface of the tissue; one of the directional anchors having an aperture for receiving a suture; and inserting a suture thread into the tissue and through the aperture and tensioning the suture thread to secure the tissue onto the directional anchors. - View Dependent Claims (22, 23)
