BONE FUSION DEVICE AND METHODS
First Claim
1. A bone fusion device comprising:
- a plurality of elongated interlockable segments, each segment having at least a first side and a second side each along a longitudinal axis of the segment;
a first engaging surface along the first side; and
a second mateably engaging surface along the second side,wherein the first engaging surface on a first one of the segments inserted into a location between bones is engageable with the second engaging surface on a second one of the segments inserted into the location so that the first and second segments are interlockable side by side in the location.

Abstract
A bone fusion device can include elongated interlockable segments, each having an engaging surface interlockable with the engaging surface of another segment. The segments can be inserted in between bones one at a time. A device can include an outer expandable component having outer expandable members insertable to a location between bones in an unexpanded configuration and an inner expander including surface engaging portions interlockable with inner surface engaging portions in the outer expandable members. A device can include the inner expander having an outwardly flared proximal portion that can interlock with the proximal end of the outer expandable members. A device can include a locking bridge expandable with an expandable body, such as an inflatable balloon, and movable to a locked expanded configuration. A bone fusion system, a bone fusion device kit, and/or a method for fusing bone can include such a bone fusion device.

17. A bone fusion device comprising:
-
an outer expandable component comprising a plurality of outer expandable members, each outer expandable member in an unexpanded configuration cooperating to define a lumen and having at least one separable interface with another one of the outer expandable members along a length of the device; a locking bridge at each interface connecting each outer expandable member with another one of the outer expandable members and movable from the unexpanded configuration to a locked expanded configuration; and an expandable body insertable into the lumen of the outer expandable component and adapted to expand the outer expandable members into the expanded configuration, wherein in the expanded configuration each locking bridge locks the outer expandable members together. - View Dependent Claims (18, 19, 20)
