Abstract
Abstract Methods, systems and apparatus are provided for interbody fusion. In some embodiments, a device is provided for fusing vertebral bodies. The device includes a shell configured to be disposed between a first body and a second body, an injection opening to receive fusing material, and a delivery hole configured to enable fusing material to flow into at least one of the first body and the second body.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
96 words
A method for interbody fusion of adjacent vertebral bodies, the method comprising: inserting a delivery device into a disc space; inserting a material restrictor in a disc space including guiding the material restrictor along a portion of the delivery device to a select position in the disc space; preparing the vertebral bodies for fusion, including drilling at least one channel from a central cavity of the material restrictor into at least one of the adjacent vertebral bodies; and delivering fusing material to the material restrictor such that the fusing material extends into the adjacent vertebral bodies.
Claim 2
Independent Claim
96 words
A method for interbody fusion of adjacent vertebral bodies, the method comprising: inserting a delivery device into a disc space; inserting a material restrictor in a disc space including guiding the material restrictor along a portion of the delivery device to a select position in the disc space; preparing the vertebral bodies for fusion, including drilling at least one channel from a central cavity of the material restrictor into at least one of the adjacent vertebral bodies; and delivering fusing material to the material restrictor such that the fusing material extends into the adjacent vertebral bodies.
Claim 3
Dependent Claim
15 words
The method of claim 1 , wherein inserting the delivery device includes retracting neural material.
Claim 4
Dependent Claim
36 words
The method of claim 1 , wherein the delivery device is provided with at least one stop configured to rest against at least one of the adjacent vertebral bodies when the delivery device is fully inserted.
Claim 5
Dependent Claim
23 words
The method of claim 1 , wherein guiding the material restrictor includes enabling operative connection between the material restrictor and the delivery device.
Claim 6
Dependent Claim
30 words
The method of claim 1 , wherein guiding the material restrictor includes operation of guiding and/or alignment structures on at least one of the delivery device and the material restrictor.
Claim 7
Independent Claim
95 words
A method for interbody fusion of adjacent vertebral bodies, the method comprising: inserting a delivery device into a disc space; inserting a material restrictor in a disc space including guiding the material restrictor along a portion of the delivery device to a select position in the disc space; preparing the vertebral bodies for fusion, wherein preparing the vertebral bodies includes drilling through at least one of a top and a bottom surface of the material restrictor; and delivering fusing material to the material restrictor such that the fusing material extends into the adjacent vertebral bodies.
Claim 8
Independent Claim
95 words
A method for interbody fusion of adjacent vertebral bodies, the method comprising: inserting a delivery device into a disc space; inserting a material restrictor in a disc space including guiding the material restrictor along a portion of the delivery device to a select position in the disc space; preparing the vertebral bodies for fusion, wherein preparing the vertebral bodies includes drilling through at least one of a top and a bottom surface of the material restrictor; and delivering fusing material to the material restrictor such that the fusing material extends into the adjacent vertebral bodies.
Claim 9
Dependent Claim
15 words
The method of claim 6 , wherein inserting the delivery device includes retracting neural material.
Claim 10
Dependent Claim
36 words
The method of claim 6 , wherein the delivery device is provided with at least one stop configured to rest against at least one of the adjacent vertebral bodies when the delivery device is fully inserted.
Claim 11
Dependent Claim
23 words
The method of claim 6 , wherein guiding the material restrictor includes enabling operative connection between the material restrictor and the delivery device.
Claim 12
Dependent Claim
30 words
The method of claim 6 , wherein guiding the material restrictor includes operation of guiding and/or alignment structures on at least one of the delivery device and the material restrictor.
Claim 13
Dependent Claim
28 words
The method of claim 6 , where preparing the vertebral bodies for fusion includes drilling at least a channel into at least one of the adjacent vertebral bodies.
