Abstract
Abstract Tools for use in the creation of cavities in bones. The tools include a probe, a cannula that provides percutaneous passageway to the interior of the treated bone, a bone tamp, and a system for delivering bone filler material into the cavity. The bone tamp has a shaft that is inserted into the bone through the cannula. The end of the shaft that is inserted into the bone may have a flapper tip that extends out of axial alignment with the shaft upon deployment by the physician. Once the tip is deployed, the bone tamp can be rotated to form the cavity. The cavity may then be treated with a medicament, filled with bone filler material, or both. Other tools and materials described herein may be used to lift or restore the treated bone closer to its natural anatomy.

Claims Analysis
Total Claims: 32
Claim 1
Independent Claim
126 words
A surgical instrument having a longitudinal axis for creating a cavity in bone, comprising: first and second members having proximal and distal ends, a tip having proximal and distal ends for creating a cavity in bone, and a fastening element for securing the tip to the first member, the first member, the tip, and the fastening element forming a joint, wherein the joint is operatively associated with the second member to provide a first mode allowing the joint to articulate freely between an initial position and a fully deployed position, a second mode that substantially immobilizes the joint in the fully deployed position, and a third mode, wherein the second member blocks the tip from articulating freely between the initial position and the fully deployed position.
Claim 2
Dependent Claim
126 words
A surgical instrument having a longitudinal axis for creating a cavity in bone, comprising: first and second members having proximal and distal ends, a tip having proximal and distal ends for creating a cavity in bone, and a fastening element for securing the tip to the first member, the first member, the tip, and the fastening element forming a joint, wherein the joint is operatively associated with the second member to provide a first mode allowing the joint to articulate freely between an initial position and a fully deployed position, a second mode that substantially immobilizes the joint in the fully deployed position, and a third mode, wherein the second member blocks the tip from articulating freely between the initial position and the fully deployed position.
Claim 3
Dependent Claim
27 words
The device of claim 1 , wherein the third mode allows the joint to articulate freely between at least one intermediate position and the fully deployed position.
Claim 4
Dependent Claim
17 words
The device of claim 1 , further comprising a collar located between the handle and the tip.
Claim 5
Dependent Claim
19 words
The device of claim 3 , wherein the collar is operably associated with the tip to articulate the joint.
Claim 6
Dependent Claim
19 words
The device of claim 4 , wherein the collar is operably associated with the tip to lock the joint.
Claim 7
Dependent Claim
19 words
The device of claim 5 , wherein the collar is operably associated with the tip to unlock the joint.
Claim 8
Dependent Claim
27 words
The device of claim 3 , wherein the third mode allows the joint to articulate freely between at least one intermediate position and the fully deployed position.
Claim 9
Dependent Claim
42 words
The device of claim 7 , wherein the at least one intermediate position and the fully deployed position define a range of free motion, and the collar is operably associated with the joint to selectively define the at least one intermediate position.
Claim 10
Dependent Claim
19 words
The device of claim 8 , wherein rotating the collar in one direction decreases the range of free motion.
Claim 11
Dependent Claim
28 words
The device of claim 9 , wherein rotating the collar through a range of motion decreases the free range of motion of the tip by a related amount.
Claim 12
Dependent Claim
20 words
The device of claim 10 , wherein the related amount is proportional to the range of motion of the collar.
Claim 13
Dependent Claim
21 words
The device of claim 11 , wherein the related amount is directly proportional to the range of motion of the collar.
