Bone treatment systems and methods

摘要

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.

主权项

1. A kit for treating bone, comprising:
one or more elongated cement-carrying devices configured to receive a volume of mixed bone fill material therein; an elongated bone fill material injector; at least one housing configured to removably receive at least one of the one or more elongated cement-carrying devices in an elongated passage thereof, the housing further comprising an energy emitter configured to apply energy to the mixed bone fill material in the cement-carrying device disposed in the housing to selectively accelerate the polymerization rate of a selected volume of the mixed bone fill material to a selected endpoint; and an energy source coupleable to the energy emitter to deliver energy thereto.
