Abstract
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.
Claims23
A system for intravertebral tissue ablation, the system comprising:
- an elongate device comprising a distal portion configured for insertion into a vertebral body, the elongate device including a utility channel comprising an open proximal end and an open distal end;
- and
- one or more components configured for insertion into the utility channel via the open proximal end;
- wherein the system includes at least one temperature sensor for measuring a temperature adjacent the open distal end;
- wherein, in an ablation configuration, the system comprises a first electrode and a second electrode disposed adjacent the open distal end, and
- wherein the first electrode and the second electrode are each configured for electrical connection to a power source such that, when the system is activated in the ablation configuration, energy flows between the first electrode and the second electrode.
A system for intravertebral tissue ablation, the system comprising:
- an elongate device comprising a distal portion including a plurality of slots, the distal portion configured for insertion into a vertebral body, the elongate device including a utility channel comprising an open proximal end and an open distal end;
- and
- one or more components configured for insertion into the utility channel via the open proximal end;
- wherein the system includes at least one temperature sensor for measuring a temperature adjacent the open distal end;
- wherein the distal portion is transitionable between a linear configuration and a non-linear configuration,
- wherein, in an ablation configuration, the system comprises a first electrode and a second electrode adjacent the open distal end, and
- wherein the first electrode and the second electrode are each configured for electrical connection to a power source such that, when the system is activated in the ablation configuration, energy flows between the first electrode and the second electrode.
A method of ablating tissue within a vertebral body, the method comprising:
- obtaining an ablation system comprising:
- an elongate device comprising a distal portion configured for insertion into a vertebral body, the elongate device including a utility channel comprising an open proximal end and an open distal end;
- and
- one or more components configured for insertion into the utility channel,
- curving the distal portion of the elongate device such that the distance between opposite sides of at least one slot disposed on the distal portion of the elongate device changes;
- and
- delivering energy to the vertebral body.
