摘要：Methods and systems for spinal radio frequency neurotomy. Systems includeneedles capable of applying RF energy to target volumes within a patient. Such targetvolumes may contain target medial branch nerves along vertebrae or rami proximate the

sacrum. Such procedures may be used to ablate or cauterize a portion of the targetednerve, thus blocking the ability of the nerve to transmit signals to the central nervoussystem. Disclosed needles may be operable to asymmetrically, relative to a centrallongitudinal axis of the needle, apply RF energy. Such asymmetry facilitates procedureswhere a tip of the needle is placed proximate to anatomical structures for locationverification. Then RF energy may be applied in a selectable direction relative to theneedle tip to ablate volumes that include the targeted medial branch nerves or rami,thus denervating facet joints or the sacroiliac joint, respectively, to relieve pain in apatient.
