TRANSDISCAL INTERBODY FUSION DEVICE AND METHOD
First Claim
1. A method of stabilizing two adjacent vertebral bodies, comprising:
- forming a disc-traversing channel in adjacent first and second vertebral bodies, positioning a system for stabilizing the adjacent vertebral bodies in the channel, the system including;
a first anchorable member and a second anchorable member, each member having a central passageway, each member having a constrained non-anchoring configuration and a released anchoring configuration; and
a connector having a central passageway, the connector attachable to the proximal end of the first anchorable member and the distal end of the second anchorable member, such that the central passageways of the anchorable members and the connector form a continuous passageway; and
anchoring the first anchorable member within the first vertebral body and the second anchorable member within the second vertebral body.

Abstract
Described herein are devices and systems for transdiscal fusion of vertebrae and methods for fusing adjacent vertebra. A system may include a device with two anchorable members connectable by an intervening connector forming a continuous passageway therethrough. An anchorable member may have a constrained non-anchoring configuration and a released anchoring configuration. The anchoring configuration typically includes a radially-expanded structure such as a plurality of struts. After positioning the anchorable members into two adjacent vertebral bodies, the anchorable members may be released from their constrained configuration so that they radially self-expand, anchoring the device across the fracture. A flowable bone-filling material may be conveyed into the passageway of the device after implantation, stabilizing it further in the vertebral implantation site.

21. A method of stabilizing adjacent vertebral bodies, comprising:
-
forming a channel in adjacent first and second vertebral bodies through adjacent endplate regions; anchoring a first anchorable member within the channel in the first vertebral body; anchoring a second anchorable member within the channel in the second vertebral body; and flowing a material through a continuous central passageway formed through the first anchorable member, the second anchorable member and a connector between the first anchorable member and the second anchorable member.
