A nerve mapping system includes an energy based dissection device, a plurality of beacons, and a processing device. The plurality of beacons are disposed in a tissue of a patient. Each beacon is adapted to transmit one or more first electrical signals within the body and receive one or more second energy signals. The processing device is adapted to determine first locations associated with the plurality of beacons, a second location associated with the energy based dissection device, and a third location associated with a nerve within the tissue, based on the one or more second signals, generate a mapping of the first locations, second location, and third location, and cause the first locations, second location, and third location to be displayed on a display device.

An injection adaptor hub for a medical catheter.

Disclosed herein is an epidural catheter with an RF generation function. More specifically, the epidural catheter with an RF generation function may include a main body, an inserting part being connected to the main body and being inserted inside a physical body, and a manipulating part being provided in the main body and being connected to the inserting part or an internal assembly part of the inserting part, so as to manipulate the inserting part or to perform a function of the inserting part, wherein two steering wires may be interpolated in the inserting part, the two steering wires being manipulated by the manipulating part so as to allow flexion of the inserting part to be controlled, and wherein, by allowing power status to be turned on/off using the main body as medium, the steering wires may act as electrodes.

System and methods for channeling a path into bone include a trocar having a proximal end, distal end and a central channel disposed along a central axis of the trocar. The trocar includes a distal opening at or near the distal end of the trocar. The system includes a curved cannula sized to be received in the central channel, and having a curved distal end configured to be extended laterally outward from the distal opening in a curved path extending away from the trocar. The curved cannula has a central passageway having a diameter configured allow a probe to be delivered through the central passageway to a location beyond the curved path.

Methods and systems for modulating intraosseous nerves (e.g., nerves within bone) are provided. For example, the methods and systems described herein may be used to modulate (e.g., denervate, ablate) basivertebral nerves within vertebrae. The modulation of the basivertebral nerves may facilitate treatment of chronic back pain. The modulation may be performed by a neuromodulation device (e.g., an energy delivery device).

The invention includes a system for generating virtual images of proposed and designated areas on a patient's anatomy that are to be treated in a RFA procedure. The images include a size, shape, and location of lesion/ablation patterns. The virtual images include dynamic (developing) or static (developed) lesions selected for the RFA procedure. The images are provided on at least one user interface that superimposes or overlays the lesion pattern(s) on an image of a patient's anatomy that undergoes the procedure. The images can be used to accurately and efficiently conduct RFA procedures and to record the procedures with enhanced visual data to confirm treated tissue areas. The invention further includes a diagnostic method of generating images in preparation for a RFA procedure, and a method of conducting the RFA procedure in which measured parameters determine the size and shape of the ablated areas achieved in the procedure.

This invention relates to high-frequency ablation of tissue in the body using a cooled high-frequency electrode connected to a high frequency generator including a computer graphic control system and an automatic controller for control the signal output from the generator, and adapted to display on a real time graphic display a measured parameter related to the ablation process and visually monitor the variation of the parameter of the signal output that is controlled by the controller during the ablation process. In one example, one or more measured parameters are displayed simultaneously to visually interpret the relation of their variation and values. In one example, the displayed one or more parameters can be taken from the list of measured voltage, current, power, impedance, electrode temperature, and tissue temperature related to the ablation process. The graphic display gives the clinician an instantaneous and intuitive feeling for the dynamics and stability of the ablation process for safety and control. This invention relates to monitoring and controlling multiple ground pads to optimally carry return currents during high-frequency tissue ablation, and to prevent of ground-pad skin burns. This invention relates to the use of ultrasound imaging intraoperatively during a tissue ablation procedure. This invention relates to the use of nerve stimulation and blocking during a tissue ablation procedure.

A device is provided for supplying electrical current to an intervertebral disc. The device comprises a cannula having a proximal end and a distal end and a longitudinal axis therebetween. The distal end comprises a beveled tip for contacting a region of the intervertebral disc, and an electrode disposed within or on a surface of the cannula adjacent to the distal end. The electrode is configured to discharge electrical current to the region of the intervertebral disc. Methods of diagnosing and/or treating discogenic back pain are also provided.

Systems, devices, and methods for transvascular ablation of target tissue. The devices and methods may, in some examples, be used for splanchnic nerve ablation to increase splanchnic venous blood capacitance to treat at least one of heart failure and hypertension. For example, the devices disclosed herein may be advanced endovascularly to a target vessel in the region of a thoracic splanchnic nerve (TSN), such as a greater splanchnic nerve (GSN) or a TSN nerve root. Also disclosed are method of treating heart failure, such as HFpEF, by endovascularly ablating a thoracic splanchnic nerve to increase venous capacitance and reduce pulmonary blood pressure.
