Bone fusion device
First Claim
1. A bone fusion device for insertion between bones comprising:
- a. first and second ends;
b. an interior cavity deposed between the first and second ends;
c. an exterior surface;
d. a conduit providing a pathway from the interior cavity to the exterior surface;
e. one or more tabs for bracing the bone fusion device in a space between the bones;
f. a positioning element positioned through the first end and substantially within the interior cavity; and
g. a plurality of extending blocks coupled to the positioning element for moving the one or more tabs.

Abstract
A bone fusion device provides stability to bones during a bone fusion period. The bones include, for example, the vertebrae of a spinal column. The bone fusion device comprises one or more extendable tabs attached to the bone fusion device by associated rotating means. The bone fusion device is preferably inserted by using an arthroscopic surgical procedure. During arthroscopic insertion of the device, the tabs are pre-configured for compactness. In this compact configuration, the tabs are preferably deposed along and/or within an exterior surface of the bone fusion device. After the bone fusion device has been positioned between the bones, one or more tab(s) are extended. In the preferred embodiment, the position of each tab is related to a positioning element and extending blocks. Typically, the tabs advantageously position and brace the bone fusion device in the confined space between the bones until the bones have fused.

11. A bone fusion device for insertion between adjacent bones, comprising:
-
a. a hollow body having one or more holes along a length of the hollow body;
b. one or more moveable tabs each attached to the hollow body by a pin and a slot, wherein the one or more moveable tabs are aligned along a surface of the hollow body in a compact position during insertion into a patient;
c. a positioning element coupled through the hollow body and substantially within the hollow body; and
d. a plurality of extending blocks coupled to the positioning element for moving the one or more moveable tabs when the positioning element is rotated. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

26. A method of implanting a bone fusion device between bones, the method comprising:
-
a. inserting the bone fusion device between the bones, wherein the bone fusion device comprises an internal cavity, an exterior surface, a positioning element, an extending block and one or more moveable tabs;
b. pre-configuring the one or more moveable tabs to lie within the exterior surface by using the positioning element with the plurality of extending blocks such that the bone fusion device has a minimized form factor; and
c. extending the one or more tabs to a desired position by moving the plurality of extending blocks by rotating the positioning element. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)
