Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
70 words
A system for treating bone comprising a cannula having an axis establishing a percutaneous path leading to inside bone, a shaft adapted to be deployed inside bone by movement within and along the axis of the cannula, and a cavity forming structure carried by the shaft comprising a surface which directly contacts and shears cancellous bone in response to rotating the shaft within and about the axis of the cannula.
Claim 2
Independent Claim
70 words
A system for treating bone comprising a cannula having an axis establishing a percutaneous path leading to inside bone, a shaft adapted to be deployed inside bone by movement within and along the axis of the cannula, and a cavity forming structure carried by the shaft comprising a surface which directly contacts and shears cancellous bone in response to rotating the shaft within and about the axis of the cannula.
Claim 3
Dependent Claim
11 words
A tool according to claim 1 wherein the shaft is flexible.
Claim 4
Dependent Claim
23 words
A tool according to claim 1 wherein the surface carries at least one marker to aid visualizing the cavity forming structure inside bone.
Claim 5
Dependent Claim
15 words
A tool according to claim 3 wherein the marker is made from a radiopaque material.
Claim 6
Dependent Claim
15 words
A tool according to claim 1 wherein the cavity forming structure comprises a resilient material.
Claim 7
Dependent Claim
12 words
A tool according to claim 5 wherein the resilient material is metal.
Claim 8
Dependent Claim
12 words
A tool according to claim 5 wherein the resilient material is plastic.
Claim 9
Dependent Claim
16 words
A tool according to claim 1 wherein the cavity forming structure comprises a shape memory material.
Claim 10
Dependent Claim
22 words
A tool according to claim 1 and further including an element to adjust extension of the cavity forming structure beyond the shaft.
Claim 11
Dependent Claim
12 words
A system according to claim 1 wherein the surface comprises a loop.
Claim 12
Independent Claim
126 words
A method for treating bone comprising the steps of providing a cannula having an axis that establishes a percutaneous path leading to inside bone, providing a shaft adapted to be deployed inside bone through the cannula including a cavity forming structure carried by the shaft comprising a surface which directly contacts and shears cancellous bone in response to rotating the shaft within and about the axis of the cannula, deploying the cannula percutaneously to establish a path leading to inside bone, introducing the shaft by movement within and along the axis of the cannula to deploy the cavity forming structure inside bone, and rotating the shaft within and about the axis of the cannula to cause the surface to shear cancellous bone and form a cavity.
Claim 13
Independent Claim
126 words
A method for treating bone comprising the steps of providing a cannula having an axis that establishes a percutaneous path leading to inside bone, providing a shaft adapted to be deployed inside bone through the cannula including a cavity forming structure carried by the shaft comprising a surface which directly contacts and shears cancellous bone in response to rotating the shaft within and about the axis of the cannula, deploying the cannula percutaneously to establish a path leading to inside bone, introducing the shaft by movement within and along the axis of the cannula to deploy the cavity forming structure inside bone, and rotating the shaft within and about the axis of the cannula to cause the surface to shear cancellous bone and form a cavity.
Claim 14
Dependent Claim
17 words
A system according to claim 11 further including the step of filling the cavity with a material.
