Abstract: Disclosed herein are high efficiency surgical devices and methods of using same using radio frequency (RF) electrical power and/or electrically heated filaments to destroy tumors, form lesions, denaturize, desiccate, coagulate and ablate soft tissues, as well as to drill, cut, resect and vaporize soft tissues. According to the principles of this invention, the electrosurgical instruments can be used with externally supplied conductive or non-conductive liquids, as well as without externally supplied liquids, a mode of operation often referred to as “dry field” environment.

Abstract: Disclosed herein are embodiments of an electrosurgical device that include one or more floating electrodes and are specifically adapted to remove, cut, resect, ablate, vaporize, denaturize, drill, coagulate and form lesions in soft tissues, with or without externally supplied liquids, preferably in combination with a resectoscope, particularly in the context of urological, gynecological, laparoscopic, arthroscopic, and ENT procedures. Specific adaptations for urological and gynecological applications, for example kidney stone removal and BPH treatment, are also described.

Abstract: Disclosed herein is a flexible single piece active element for use in connection with aspirating electrosurgical ablators, particularly those configured for bulk tissue vaporization. The active electrode elements of the present invention provide a simple construction suitable for use with a wide array of electrosurgical components and adjustable to wide range of angled positions to permit access to a variety of tissues, in an array of diverse environments and address a host of ablation needs. Additionally, the novel geometry and positioning of both ablation surface and aspiration ports permit aspiration flow to remove primarily waste heat rather than process heat, to thereby improve vaporization efficiency and reduce procedure time. Thus, active electrodes and ablation devices of the present invention maximize efficiency and adaptability while minimizing manufacturing cost and device profile.

Abstract: Herein disclosed are dual-mode electrosurgical devices designed to function in a first mode in which high-density RF energy is used to cut or vaporize tissue, and then a second mode in which lower-density RF energy desiccates tissue to produce hemostasis, as well as methods of performing electrosurgery using same. Devices formed in accordance with the principles of this invention may be used for any surgical procedure in which highly vascular tissue is cut electrosurgically in a dry or semi-dry field, examples of which include tonsillectomy, liver resection, and cosmetic procedures such as breast augmentation, breast reduction, breast mastopexy, and abdominoplasty.

Abstract: An electrosurgical instrument, system, and methods are provided for the vaporization, cutting, coagulation, or treatment of tissue in the presence of an electrically conductive fluid medium. The electrosurgical probe comprises at least one active electrode, and at least one “floating” electrode having at least one end in close proximity to at least one active electrode. The floating electrode is not connected in any way to the electrosurgical power supply, but rather has a “floating” potential determined by the shape and position of the electrode. The floating electrode increases current density in the region of the probe distal end.

Abstract: Disclosed herein is a distal end electrode assembly for use in connection with electrosurgical devices, particularly those adapted for the modification, sculpting, resection, removal, or vaporization of tissue, configured for coagulation, cauterization or hemostasis purposes, or utilized for thermal treatment of normal and tumorous tissues. In the context of the present invention, mechanical fastening means, epoxies and other high-temperature adhesives connecting electrode(s) to insulator(s) are replaced with brazed joints to yield electrosurgical devices capable of safely and reliably operating at high power densities and elevated temperatures without thermal failure of the bonds between the electrode and the insulator.

Abstract: The present invention relates to electrosurgical probes suitable for tissue vaporization and cutting of tissue structures, more particularly for performing electrosurgical cutting, ablation (volumetric tissue vaporization), coagulating and/or modification within a body tissue, cavity or vessel or on the surface of a patient. The system and method of the present invention optionally include structure for irrigation and/or aspiration of the surgical site and therefore may be used in relatively dry environments such as in the context of oral, otolaryngological, laparoscopic, and dermatologic procedures.
