US Patent 9717551 Intravertebral tissue ablation device and method

A tissue ablation device is provided for use in soft tissue and/or in bone. It is configured to include an inner probe with a first electrode and a second electrode and an outer needle through which the inner probe extends. After the inner probe is directed therewithin to a target, the outer needle can be withdrawn to expose space between the first and second electrodes to form an RF or other energy field for tissue ablation therebetween upon actuation of an energy source. Such embodiments may include methods for tissue ablation and placement of stabilizing materials.
