Abstract:
A device comprising:a generally flexible substantially tabular member sized to fit and expand transversely into a hollowed region of an intervetebral space or intravertebral space; the substantially tubular member defining an interior space; the interior space extending from a first end of the substantially tubular member to second end of the substantially tubular member; at least one end defining an opening; the opening in fluid communication with the interior space; the substantially tubular member constructed and arranged to expand from a reduced state to an expanded state by the introduction of fill material into the interior space; the substantially tubular member including a plurality of pores; the plurality of pores being sized to allow ingress and egress of liquids, solutions or small particle suspensions and ingrowth of bony trabeculae or fibrous elements into and through the device when the device is positioned in the hollowed region of a intervertebral space or intravertebral space; the plurality of pores being sized to retain the fill material within the interior space of the substantially tubular member; the substantially tubular member including at least one fill opening through which the fill material may be introduced into the interior space; the at least one fill opening including at least one of the plurality of pores.
