Abstract: Methods and systems for spinal radio frequency neurotomy. Systems include needles capable of applying RF energy to target volumes within a patient. Such target volumes 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 targeted nerve, thus blocking the ability of the nerve to transmit signals to the central nervous system. Disclosed needles may be operable to asymmetrically, relative to a central longitudinal axis of the needle, apply RF energy. Such asymmetry facilitates procedures where a tip of the needle is placed proximate to anatomical structures for location verification. Then RF energy may be applied in a selectable direction relative to the needle 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 a patient.

Abstract: A device includes a first unit and a second unit. The first unit comprises a first C-shaped portion, a first bridge portion, and a first U-shaped portion. The first U-shaped portion comprises a first projection extending therefrom. The second unit comprises a second C-shaped portion, a second bridge portion, and a second U-shaped portion. The second U-shaped portion comprises a second projection extending therefrom. The first projection interlocks with the second projection when the first C-shaped portion and the second C-shaped portion are fastened to a plate.

Abstract: Systems and methods for tissue ablation. Systems include needles with deployable filaments capable of producing asymmetrical offset lesions at target volumes, which may include a target nerve. 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 offset 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.

Abstract: Representations of physiological structures for thermal treatment simulation. Training operators of the treatment devices by physically illustrating thermal profiles on organs, tissue, and nerves in real time may advantageously provide an understanding of heating and/or cooling effects. An experimenter may witness the thermal effects of lesion creation (e.g., RF lesion creation) rather than just monitoring a thermocouple temperature and assuming end-organ/tissue/nerve effects.

Abstract: A method of outputting an alert indicating that an unauthorized event has occurred. The method includes obtaining a status from a sensor and retrieving personnel information from a database, the personnel information relating to the sensor. The method also includes generating the alert, applying a filter to determine whether to modify a severity of the alert, and outputting the alert.
