1. A method for closing a fissure in a region of tissue having an inner surface and an outer surface, the method comprising:
- providing a first transverse anchor having a first surface, a second surface and a hole extending from the first surface to the second surface, and a first flexible longitudinal fixation component having a first end and a second end, wherein the first flexible longitudinal fixation component is passed through the hole in the first transverse anchor and secured to the first transverse anchor with a first knot tied on the second surface of the first transverse anchor;
providing a second transverse anchor having a first surface, a second surface and a hole extending from the first surface to the second surface, and a second flexible longitudinal fixation component having a first end and a second end, wherein the second flexible longitudinal fixation component is passed through the hole in the second transverse anchor and secured to the second transverse anchor with a second knot tied on the second surface of the second transverse anchor;
positioning the first surface of the first transverse anchor on one side of the fissure and against the inner surface of the tissue, with the second end of the first flexible longitudinal fixation component extending to the outer surface of the tissue on the first side of the fissure;
positioning the first surface of the second transverse anchor on the second side of the fissure and against the inner surface of the tissue, with the second end of the second flexible longitudinal fixation component extending to the outer surface of the tissue on the second side of the fissure;
tensioning the first flexible longitudinal fixation component and second flexible longitudinal fixation component so as to reduce the size of the fissure; and
securing the first flexible longitudinal fixation component to the second flexible longitudinal fixation component.

Abstract
A method for closing a fissure in a region of tissue having an inner surface and an outer surface, the method comprising:
- providing at least a pair of transverse anchor components, each transverse anchor component being coupled to at least one flexible longitudinal fixation component having a longitudinal axis;
- placing the transverse anchor components relative to the inner surface of the tissue on both sides of the fissure such that an exposed end of a flexible longitudinal fixation component extends through the tissue and past the outer surface of the tissue on both sides of the fissure;
- applying axial tension to the exposed ends; and
- anchoring the exposed ends.

2. A method for closing a fissure in the annulus of an intervertebral disc, comprising:
-
providing a first transverse anchor having a first surface, a second surface and a hole extending from the first surface to the second surface, and having a first filament extending therefrom, wherein the first filament comprises a first end and a second end, and further wherein the first filament is passed through the hole in the first transverse anchor and secured to the first transverse anchor with a first knot tied on the second surface of the first transverse anchor; providing a second transverse anchor having a first surface, a second surface and a hole extending from the first surface to the second surface, and having a second filament extending therefrom, wherein the second filament comprises a first end and a second end, and further wherein the second filament is passed through the hole in the first transverse anchor and secured to the first transverse anchor with a second knot tied on the second surface of the second transverse anchor; advancing said first transverse anchor through the annulus of the intervertebral disc on one side of the fissure so that the first transverse anchor is disposed against an inner surface of the annulus and the first filament extends through the wall of the annulus on one side of the fissure, and advancing said second transverse anchor through the annulus of the intervertebral disc on a second side of the fissure so that the second transverse anchor is disposed against an inner surface of the annulus and the second filament extends through the wall of the annulus on the second side of the fissure; applying tension to the first and second filaments so as to close the fissure; and welding the first filament to the second filament.
