Abstract
A repair system including a closure prosthesis and deployment device, and associated methods for repairing any imperfection including a flaw, hole, tear, bulge, or, in some cases, a deliberate cut or incision in any tissue including an intervertebral disc. The prosthesis has first and second side portions with a connecting central portion, and is designed to span an imperfection with opposite ends positioned on opposite sides of the imperfection. The prosthesis may include anchoring features including barbs and/or members that extend transversely. The deployment device can include a cannula for positioning the prosthesis near the imperfection, and, in some cases, a mechanism that may cause the two sides of the prosthesis to be deployed in a specific order.
