Tissue repair system
First Claim
1. A method for attaching a first tissue with a second tissue using a prosthesis having a central portion connected to a first end portion and a second end portion, the first end portion having a first anchoring device and the second end portion having a second anchoring device, comprising the steps of:
- inserting a first end portion of prosthesis into a first portion of the first tissue by moving an actuator a first distance;
wherein the first end portion is disposed within a first channel formed in a first penetrating memberejecting the first end portion of the prosthesis from the first channel of the first penetrating member and into the first tissue prior to implanting the second end portion, wherein the second end portion is disposed within a second channel formed in a second penetrating member; and
controlling the insertion of the second end portion of the prosthesis into the second tissue by moving the actuator a second distance beyond the first distance.

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 is disclosed. 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 or the same side of the imperfection. The prosthesis may include anchoring features including barbs and/or members that extend transversely or at different angles. 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.

10. A method for repairing an imperfection associated with a tissue comprising the steps of:
-
inserting a prosthesis deployment device into a patient, wherein a prosthesis is positioned proximate a distal end of the prosthesis deployment device wherein the prosthesis has a central portion connected to the first end portion, wherein the first end portion is disposed within a first penetrating member of the prosthesis deployment device and a second end portion connected to the central portion, wherein the second end portion is disposed within a second penetrating member of the prosthesis deployment device;
the first end portion having a first anchoring device, and the second end portion having a second anchoring device;positioning the distal end of the prosthesis deployment device proximate the tissue; inserting a first penetrating member of the prosthesis deployment device into a first portion of the tissue by moving a first actuator associated with the prosthesis deployment device, wherein the first portion of the tissue is on a first side of the imperfection, and wherein the first penetrating member of the prosthesis deployment device creates its own path through the first portion of the tissue; ejecting a first end portion of a prosthesis from the first penetrating member and into the first portion of the tissue by moving a second actuator associated with the prosthesis deployment device while a second end portion of the prosthesis remains generally stationary within the second penetrating member of the prosthesis deployment device; inserting the second end portion of the prosthesis into a second portion of the tissue that is spaced from the first portion of the tissue by moving the second actuator, wherein the second portion of the tissue is on a second side of the imperfection, and wherein the movement of the second end portion of the prosthesis is independent from the movement of the first end portion of the prosthesis; and spanning the imperfection with the central portion of the prosthesis. - View Dependent Claims (11, 12, 13, 14)

15. A method for attaching a first tissue with a second tissue comprising the steps of:
-
positioning a device configured to deliver a prosthesis proximate the first tissue and the second tissue, wherein a prosthesis is associated with a distal end of the device configured to deliver a prosthesis, wherein the prosthesis has a central portion connected to a first end portion and a second end portion, wherein the first end portion has a first anchoring device, and the second end portion has a second anchoring device; positioning the device configured to deliver a prosthesis so that the first end portion of the prosthesis is positioned proximate the first tissue and the second end portion of the prosthesis is positioned proximate the second tissue; penetrating the first tissue with a first member of the device configured to deliver a prosthesis, wherein the first end portion of the prosthesis is positioned within a first hollow portion of the first member of the device configured to deliver a prosthesis; inserting the first end portion of the prosthesis into the first tissue while retaining the second end portion of the prosthesis within the device, wherein the first end portion of the prosthesis is inserted by moving an actuator associated with the device configured to deliver a prosthesis a first distance to eject the first end portion of the prosthesis from the first hollow portion of the first member of the device configured to deliver a prosthesis; penetrating the second tissue with a second member of the device configured to deliver a prosthesis after the first end portion of the prosthesis has stopped moving, wherein the second end portion of the prosthesis is positioned within a second hollow portion of the second member of the device configured to deliver a prosthesis; and inserting the second end portion of the prosthesis into the second tissue by moving the actuator associated with the device configured to deliver a prosthesis a second distance to eject the second end portion of the prosthesis from the second hollow portion of the second member of the device configured to deliver a prosthesis so that the central portion of the prosthesis spans between the first tissue and the second tissue. - View Dependent Claims (16, 17, 18, 19, 20)
