Methods of repairing herniated segments in the disc

Abstract

Systems for minimally invasive disc augmentation include an anulus augmentation component and a nucleus augmentation component. Both are suited for minimally invasive deployment. The nucleus augmentation component restores disc height and/or replaces missing nucleus pulposus. The anulus augmentation component shields weakened regions of the anulus fibrosis and/or resists escape of natural nucleus pulposus and/or the augmentation component. Methods and deployment devices are also disclosed. Method of supporting and augmenting a nucleus pulposus by inserting a flexible biocompatible material into the disc space using an anchoring means are also provided.

1 . A method of facilitating treatment of an intervertebral disc in a spine comprising:
 introducing a distal end of an implant delivery device be and at least a first outer layer of an anulus of an intervertebral disc, the distal end configured to deliver an implant within the intervertebral disc;   delivering an implant in the intervertebral disc using the implant delivery device,   wherein the implant is configured to be held alone an innermost layer of the anulus in a nuclear space of the intervertebral disc;   inserting at least one fixation device into a vertebral body surrounding the intervertebral disc;   connecting the at least one fixation device to the implant and   removing the implant delivery device.   
     
     
         2 . The method of  claim 1 , wherein the at least one fixation device comprises a suture. 
     
     
         3 . The method of  claim 2 , wherein the suture is resorbable. 
     
     
         4 . The method of  claim 1 , wherein the at least one fixation device comprises a woven or web-like material. 
     
     
         5 . The method of  claim 1 , wherein the at least one fixation device comprises a connection member that is knotted. 
     
     
         6 . The method of  claim 1 , wherein the at least one fixation device comprises a resorbable material. 
     
     
         7 . The method of  claim 1 , wherein the at least one fixation device comprises at least one connection member and at least one anchor portion. 
     
     
         8 . The method of  claim 7 , wherein the at least one connection member comprises a suture or wire. 
     
     
         9 . The method of  claim 7 , wherein the at least one anchor portion comprises at least one barb. 
     
     
         10 . The method of  claim 1 , wherein the implant is cap-shaped, bar-shaped, plate-shaped, or bead-shaped. 
     
     
         11 . The method of  claim 1 , wherein the at least one fixation device is affixed to said vertebral body with a cement or surgical adhesive. 
     
     
         12 . The method of  claim 1 , wherein the at least one fixation device comprises a screw anchor, and wherein said anchor is screwed into the vertebral body. 
     
     
         13 . The method of  claim 1 , wherein the implant delivery device carries said implant. 
     
     
         14 . The method of  claim 1 , wherein the implant delivery device comprises a handheld grasping tool. 
     
     
         15 . The method of  claim 1 , wherein the implant delivery device comprises a delivery tube. 
     
     
         16 . A method of facilitating treatment of an intervertebral disc in a spine comprising:
 providing an implant delivery system comprising an implant delivery device, at least one fixation device, and an implant, the implant delivery system configured for:
 (i) introducing a distal end of the implant delivery device beyond at least a first outer layer of an anulus of an intervertebral disc, the distal end configured to deliver the implant within the intervertebral disc; 
 (ii) delivering the implant in the intervertebral disc using the implant delivery device, 
 wherein the implant is configured to be held along an innermost layer of the anulus in the space occupied by the nucleus; and 
 (iii) inserting the at least one fixation device into a vertebral body surrounding the intervertebral disc. 
   
     
     
         17 . The method of  claim 16 , wherein the implant delivery system is further configured for connecting the at least one fixation device to the implant during delivery. 
     
     
         18 . The method of  claim 16 , wherein the at least one fixation device comprises at least one anchor portion and at least one connection member. 
     
     
         19 . The method of  claim 16 , wherein the implant delivery device carries said implant. 
     
     
         20 . The method of  claim 16 , wherein the implant delivery device is a handheld grasping tool or a delivery tube.
