Abstract

Systems and methods for treating bone, such as vertebral compression fractures are disclosed. A method includes controllably applying energy to a bone cement volume outside of a patient'"'"'s body to selectively accelerate the polymerization rate of the bone fill material volume prior to introduction into a bone. The method further includes sequentially introducing a plurality of cement carrying structures with the accelerated polymerization rate bone cement volume into the bone. A system for use in the method includes at least one elongated cement-carrying structure sized to carry a bone cement volume therein and an energy source operatively coupleable to the cement-carrying structure. The energy source applies energy to the bone cement volume to selectively accelerate a polymerization rate thereof. An elongated injector insertable into the bone has a passageway that removably receives the elongated cement-carrying structure to allow delivery of the accelerated polymerization rate bone cement into the bone.

Claims

1. A system for treating bone, comprising:

two or more elongated cement-carrying devices configured to receive a volume of mixed bone fill material therein;

two or more sleeves, each sleeve configured to removably receive at least a portion of an elongated cement-carrying device of the two or more elongated cement-carrying devices in an receiving channel thereof;

a controller configured to control the polymerization rate of the mixed bone fill material such that the mixed bone fill material of at least two of the two or more elongated cement-carrying devices have different viscosities;

wherein each of two or more sleeves further comprises an energy emitter, wherein the controller is configured to control the application of energy from the energy emitters so that different levels of energy are transmitted from the emitters to the mixed bone fill material in the two or more elongated cement-carrying devices disposed in the two or more sleeves; and

an elongated bone fill material injector, wherein the elongated bone fill material injector is sized to receive an elongated cement-carrying device of the two or more elongated cement-carrying devices therein.

2. The system of claim 1, wherein at least one sleeve of the two or more sleeves further comprises an energy emitter configured to apply energy to the mixed bone fill material in the cement-carrying device disposed in the at least one sleeve.

3. The system of claim 2, further comprising an energy source coupleable to the energy emitter to deliver energy thereto.

4. The system of claim 2, wherein the energy emitter is separate from the two or more elongated cement-carrying devices.

5. The system of claim 1, wherein at least one sleeve of the two or more sleeves further comprises a cooling system configured to retard the polymerization rate of the mixed bone fill material in the cement-carrying device disposed in the at least one sleeve.

6. The system of claim 1, further comprising a bone fill source.

7. The system of claim 1, wherein each elongated cement-carrying device has a corresponding sleeve.

8. The system of claim 1, further comprising a data acquisition system that communicates with the controller, wherein the data acquisition system is configured to provide information indicative of the viscosity of the mixed bone fill material.
