Claim 13
Dependent Claim
49 words
12 . An implantable device for insertion into a cavity in a vertebral body comprising: a container including; an upper wall member; a lower wall member; a circumfrential wall member; a set of ribs extending from said upper wall to said lower wall, thereby forming a set of channels.
Claim 14
Dependent Claim
49 words
12 . An implantable device for insertion into a cavity in a vertebral body comprising: a container including; an upper wall member; a lower wall member; a circumfrential wall member; a set of ribs extending from said upper wall to said lower wall, thereby forming a set of channels.

20 . A method of treating an vertebral body having a superior endplate and an inferior endplate, comprising the steps of: inserting a container into an vertebral body; deploying said container within said vertebral body; injecting a bone filler material into said container under pressure; whereby said pressure supplies a distraction force to move said superior and inferior endplates apart; ending injection after said endplates have moved apart.
Claim 23
Dependent Claim
68 words
20 . A method of treating an vertebral body having a superior endplate and an inferior endplate, comprising the steps of: inserting a container into an vertebral body; deploying said container within said vertebral body; injecting a bone filler material into said container under pressure; whereby said pressure supplies a distraction force to move said superior and inferior endplates apart; ending injection after said endplates have moved apart.

21 . The method of claim 20 wherein said filler material is selected from the group comprising: bone cement, human bone graft allograft; human bone graft autograft; synthetic derived bone substitute; sulfate and/or calcium phosphate, hydroxylapatite.
Claim 25
Dependent Claim
60 words
22 . A method of treating an vertebral body comprising the steps of: creating a cavity in the vertebral body through an access aperture; inserting a container into said vertebral body; said container having a fill passage coupled to said container; deploying said container within said vertebral body; injecting a bone filler material into said container through said fill passage.
Claim 26
Dependent Claim
60 words
22 . A method of treating an vertebral body comprising the steps of: creating a cavity in the vertebral body through an access aperture; inserting a container into said vertebral body; said container having a fill passage coupled to said container; deploying said container within said vertebral body; injecting a bone filler material into said container through said fill passage.
Claim 27
Dependent Claim
135 words
23 . A method of treating an vertebral body comprising the steps of: inserting a container into an vertebral body; said container having a fill passage coupled to said container; said container having a porous outer membrane sufficiently porous to allow filler material under pressure to leave the container after filling the container; deploying said container within said vertebral body injecting a filler material into said container through said fill passage with bone filler material in a sufficient volume to allow the bone filler material to exit the container and interdigitates with cancellous bone within said vertebral body thereby reinforcing said bone and stabilizing fractures in said bone; said container membrane porosity sufficient to provide resistance to the flow of said bone filler material to generate force to move the endplates of said vertebral body.
Claim 28
Dependent Claim
135 words
