Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
99 words
A method for treating or preventing a vertebral compression fracture comprising the steps of: inserting an insertion device percutaneously into a vertebral body; inserting a cavity-forming device through the insertion device into an area of cancellous bone in the vertebral body; displacing cancellous bone with the cavity-forming device to create a cavity and a barrier region of compressed cancerous bone substantially surrounding the cavity; and filling at least a portion of the cavity with a bone filler, and inserting a cavity-forming device into the cavity and compressing at least a portion of the bone filler against the barrier region.
Claim 2
Independent Claim
99 words
A method for treating or preventing a vertebral compression fracture comprising the steps of: inserting an insertion device percutaneously into a vertebral body; inserting a cavity-forming device through the insertion device into an area of cancellous bone in the vertebral body; displacing cancellous bone with the cavity-forming device to create a cavity and a barrier region of compressed cancerous bone substantially surrounding the cavity; and filling at least a portion of the cavity with a bone filler, and inserting a cavity-forming device into the cavity and compressing at least a portion of the bone filler against the barrier region.
Claim 3
Dependent Claim
12 words
The method of claim 1 wherein the insertion device comprises a needle.
Claim 4
Dependent Claim
13 words
The method of claim 2 , wherein the needle is an eleven-gauge needle.
Claim 5
Dependent Claim
30 words
The method of claim 1 wherein the cavity-forming device is selected from the group consisting of a mechanical tamp, a reamer, a drill, a hole puncher and a balloon catheter.
Claim 6
Dependent Claim
35 words
The method of claim 1 wherein the cavity-forming device is a balloon catheter comprising: a tube comprising a distal end and a proximal end; an expandable structure; and a fitting comprising at least one port.
Claim 7
Dependent Claim
27 words
The method of claim 5 wherein the tube of the balloon catheter is hollow and comprises at least one opening near the distal end of the tube.
Claim 8
Dependent Claim
21 words
The method of claim 6 wherein the expandable structure of the catheter is bonded to the distal end of the tube.
Claim 9
Dependent Claim
43 words
The method of claim 7 wherein the expandable structure is inflated with an inflation medium, thereby forming a cavity and a barrier surrounding the cavity within the vertebral body; and wherein the expandable structure is subsequently deflated and removed through the insertion device.
Claim 10
Dependent Claim
23 words
The method of claim 8 wherein the inflation medium is selected from the group consisting of air, nitrogen, saline, water and combinations thereof.
Claim 11
Dependent Claim
12 words
The method of claim 1 wherein the bone filler is a polymethylmethacrylate.
Claim 12
Independent Claim
174 words
A method for treating or preventing a vertebral compression fracture comprising the steps of: inserting a spinal needle of a needle assembly percutaneously through a pedicle into a vertebral body; inserting a balloon catheter through the spinal needle into an area of cancerous bone within the vertebral body, so that the distal end of the balloon catheter extends out of the distal end of the spinal needle; inflating the balloon catheter with an inflation medium such that inflation of the distal end of the balloon catheter extending from the spinal needle displaces cancerous bone around the inflating balloon, forming a barrier region around the balloon catheter that at least partly closes large cracks or veins within the cancellous bone area of the vertebral body; deflating the balloon catheter and leaving a cavity within the cancellous bone area of the vertebral body; removing the balloon catheter from the vertebral body through the needle assembly; filling the cavity with a bone filler; and compressing at least a portion of the bone filler against the barrier region.
Claim 13
Independent Claim
174 words
A method for treating or preventing a vertebral compression fracture comprising the steps of: inserting a spinal needle of a needle assembly percutaneously through a pedicle into a vertebral body; inserting a balloon catheter through the spinal needle into an area of cancerous bone within the vertebral body, so that the distal end of the balloon catheter extends out of the distal end of the spinal needle; inflating the balloon catheter with an inflation medium such that inflation of the distal end of the balloon catheter extending from the spinal needle displaces cancerous bone around the inflating balloon, forming a barrier region around the balloon catheter that at least partly closes large cracks or veins within the cancellous bone area of the vertebral body; deflating the balloon catheter and leaving a cavity within the cancellous bone area of the vertebral body; removing the balloon catheter from the vertebral body through the needle assembly; filling the cavity with a bone filler; and compressing at least a portion of the bone filler against the barrier region.
Claim 14
Dependent Claim
12 words
The method of claim 11 wherein the inflation medium comprises sterile saline.
Claim 15
Dependent Claim
11 words
The method of claim 12 wherein the bone filler is polymethylmethacrylate.
