Claims

a first beam and a second beam each extending along a longitudinal direction;
a connecting member bridging a first proximal portion of the first beam to a second proximal portion of the second beam such that the first beam is substantially aligned with the second beam; and,
a first barb protruding from an interior of the first beam, the first barb extending obliquely in a generally proximal direction;
a second barb protruding from inside the second beam, the second barb extending obliquely in a generally proximal direction;
the first barb includes a proximally facing surface separated from the first beam by a recess;
Surgical anchoring element.

The anchoring element of claim 1, further comprising a reinforcing ridge disposed within the first recess.

2. The method of claim 1, wherein the first beam, the second beam, the connecting member, the first barb, and the second barb comprise a monolithic structure formed from a single unitary piece of material. Anchoring element as described.

the first beam extends between a proximal end and a distal end, the proximal end terminating in a first surface having a first shape, and the distal end having a substantially different shape; Anchoring element according to claim 1, which terminates in a surface.

6. The anchoring element of claim 5, wherein the proximal end terminates in a substantially circular surface and the distal end terminates in a substantially teardrop-shaped surface.

7. The anchoring of claim 6, wherein the proximal end terminates in a surface aligned with a transverse axis and the distal end terminates in a surface oriented at an oblique angle to the transverse axis. element.

8. An anchoring element according to claim 7, wherein the third barb is continuous with the distal end of the first beam.

A deployment device for deploying a surgical anchoring element, the deployment device comprising:
at least one pair of needle members configured to extend from a distal end of the deployment device and configured to receive a beam of a surgical anchoring element;
at least one anchor engagement rod configured to engage an anchoring element when disposed within the needle member;
at least one configured to translate the pair of needles and the anchoring element from a first proximal position within the deployment device to a second distal position extending from the distal end of the deployment device. A push-in member;
upon retraction of the needle member, the anchor engagement rod maintains the anchoring element in the second distal position such that the anchoring element is released from the needle member;
