Abstract:
1. A bone fusion device comprising: an elongated structure extending along a longitudinal axis and comprising at least two anchor portions and at least one deformable segment connected on each end to one of the at least two anchor portions, each deformable segment comprising a plurality of spaced apart deformable members deformable from an unexpanded configuration to an expanded configuration, each of the deformable members individually having an outer cross section in the shape of a circle extending axially along the longitudinal axis of the device from a first of the anchor portions to a second of the anchor portions, the device being implantable between two bone structures in the unexpanded configuration, wherein compression of the deformable members along the longitudinal axis of the device deforms the deformable members to the expanded configuration into contact with the two bone structures.
