A dental treatment apparatus includes a holder, a power supply, root canal length measurement circuitry, and control circuitry. The holder holds an electrode placed in a root canal. The power supply energizes file with a high-frequency current. The root canal length measurement circuitry electrically measures a position of a distal end of electrode in the root canal. The control circuitry causes, in accordance with information on the position of the distal end of the electrode measured by root canal length measurement circuitry, the power supply to control a current value of the high-frequency current which energizes the electrode.

Systems for controlling ablation procedures that include a user interface. The user interface can include a display; and a memory with a computer executable method stored thereon, the computer executable method adapted to cause to be displayed on the display a plurality of interactive elements for controlling one or more aspects of the ablation.

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).

Methods and surgical devices for performing an anastomosis of a living tissue. More particularly the methods and devices relate to anastomosis of tissue performed through tissue fusion performed by delivering energy to the tissue.

A device for fragmenting a surgical implant includes a cap. The cap includes a first channel extending from a first end of the cap to the second end of the cap. The device includes a first electrode, a second electrode, and an endoscope coupled with the cap.

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.

Disclosed herein is a system for treating skin and/or nails with cold plasma. The system includes a discharge device, which includes a handle and an applicator mounted thereon, and control infrastructure, which includes a waveform generator. The applicator includes an elongated tube housing therein a cathode. The handle includes a flyback amplifier. The waveform generator is configured to induce the flyback amplifier to establish a voltage at the cathode. The voltage produced by the flyback amplifier is configured to generate a self-sustaining Townsend avalanche when a distal end of the tube is positioned sufficiently near a target site on a skin surface or a nail of a subject, such that a cold plasma discharge is produced and directed at the target site and having an average power between about 0.1 .Math.W and about 10 .Math.W, so that the target site is not heated.

A surgical tool according to at least one embodiment of the present disclosure includes a proximal end; and a distal end, the distal end including a first electrode; a second electrode different from the first electrode; and a thermal bridge that is disposed between the first electrode and the second electrode and that electrically isolates the first electrode from the second electrode.

Catheter systems, tools and methods are disclosed for the selective and rapid application of DC voltage pulses to drive irreversible electroporation for minimally invasive transurethral prostate ablation. In one embodiment, a switch unit is used to modulate and apply voltage pulses from a cardiac defibrillator, while in another, the system controller can be configured to apply voltages to an independently selected multiplicity or subsets of electrodes. Devices are disclosed for more effective DC voltage application including the infusion of cooled fluid to elevate the irreversible electroporation threshold of urethral wall tissue and to selectively ablate regions of prostate tissue alone.

Ablation catheters and systems include flexible catheter tips with a distal needle or ports for delivery of an ablative agent to a target tissue. Pressure monitoring during ablation ensure operation is performed within safe limits and with desired efficacy. Positioning elements help maintain the devices in the proper position with respect to the target tissue and also prevent the passage of ablative agent to normal tissues.
