Abstract: Provided herein are several embodiments for an anchor device for insertion into a bone, all of which include a post suitable for implantation into a bone, and a cord housing coupled to the post. The cord housing has a lower housing with a cradle for receiving therein at least one cord, and an upper housing with a clamp for placement over the at least one cord inserted into the cradle. The joining of the upper housing to the lower housing forms a cord channel by the cradle and the clamp, to encase the at least one cord placed into the cradle. The cord housing also has means for fastening the upper housing to the lower housing and securing the at least one cord within the cord channel.

Abstract: An expandable cage for enhancing fusion of adjacent vertebral bodies includes a housing having a top and a bottom surface. A flexible mesh couples the top and bottom surfaces to allow movement of the top and bottom plate members relative to one another. An aperture formed on the expandable cage receives a selected material. The flexible mesh is in a normally collapsed position but enables the top and bottom plate members to move farther relative to one another when the housing is injected with the selected material. A portion of the flexible mesh expands laterally out of the housing when the housing is injected with the selected material. The top and bottom surfaces are made from carbon fiber, titanium, steel, implantable plastics, or other suitable material. The injected material may be a bone graft or a bone graft substitute (e.g., bone morphogenetic protein).
