Abstract
Apparatus for radiofrequency neurotomy are disclosed. Needles with deployable filaments capable of producing lesions at target volumes, which include a target nerve, and systems including such needles are disclosed. Ablation of at least a portion of the target nerve may inhibit the ability of the nerve to transmit signals, such as pain signals, to the central nervous system. The lesion may facilitate procedures by directing energy towards the target nerve and away from collateral structures. Example anatomical structures include lumbar, thoracic, and cervical medial branch nerves and rami and the sacroiliac joint.
