    摘要: Spinal tumor ablation devices and related systems and methods are disclosed. Some spinal tumor ablation devices include electrodes that are fixedly offset from one another. Some spinal tumor ablation devices include a thermal energy delivery probe that has at least one temperature sensor coupled thereto. The position of the at least one temperature sensor relative to other components of the spinal tumor ablation device may be controlled by adjusting the position of the thermal energy delivery probe in some spinal tumor ablation devices. Some spinal tumor ablation devices are configured to facilitate the delivery of a cement through a utility channel of the device.

    摘要: The present invention relates in certain embodiments to medical devices for treating vertebral compression fractures. More particularly, embodiments of the invention relate to instruments and methods for controllably restoring vertebral body height by controlling the flow of bone cement into the interior of a vertebra and the application of forces causes by the cement flow. An exemplary system utilizes Rf energy in combination a conductive bone cement for selectively polymerizing the inflow plume to increase the viscosity of the cement. In one aspect of the invention, the system utilizes a controller to control bone cement flow parameters to either allow or disallow cement interdigitation into cancellous bone. A method of the invention includes pulsing the flows of bone cement wherein high acceleration of the flow pulses can apply expansion forces across the surface of the cement plume to reduce a vertebral fracture.

    摘要: Systems and methods for treating vertebral compression fractures are discussed. In an embodiment, a method includes mixing bone cement precursors thereby causing a first chemical curing reaction characterized by a first time-viscosity profile, controllably applying energy to the bone cement from an external source to modify the first time-viscosity profile to a second time-viscosity profile, and injecting the cement into bone at a substantially constant viscosity greater than about 1000 Pa·s to greater than about 5000 Pa·s over an extended working time. In another embodiment, a bone cement injector system is provided that includes a first handle component that is detachably coupled to a second sleeve component having a distal end for positioning in bone and a flow channel extending through the first and second components. The system includes first and second thermal energy emitters for delivering energy to bone cement flows in a flow channel portion in the first and second components, respectively.

    摘要: A bone anchor can include an elongated body and a plurality of separate elements. The bone anchor can be configured to be insertable into bone. The bone anchor can be coupleable to a spine treatment apparatus. The bone anchor can be revisable so that after a treatment interval attached to a spine treatment apparatus, the spine treatment apparatus can be detached and the bone anchor revised by removing the plurality of separate elements from the bone thus allowing a new anchor to be implanted in the bone.

    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.
