Patent number: 9730751Abstract: 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.Type: GrantFiled: July 28, 2016Date of Patent: August 15, 2017Assignee: ElectroMedical Associates, LLCInventors: Robert A.

Patent number: 9168084Abstract: 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.Type: GrantFiled: May 10, 2011Date of Patent: October 27, 2015Assignee: ElectroMedical Associates, LLCInventors: Yuval Carmel, Anatoly Shkvarunets, Robert A.

Publication number: 20150196350Abstract: Conventional electrosurgical devices used in a conductive fluid environment have one or more electrodes at the active electrode potential, and one or more return electrodes at the return potential. The shape of the electric field and the current density for a given power setting are determined primarily by the configuration, size and relative locations of the active and return electrodes and of dielectric elements surrounding and separating the electrodes. Two potentials are supplied to the site by the electrosurgical power supply. Disclosed herein are mechanisms and methods for enhancing the effectiveness of an electrosurgical device in a conductive fluid environment that utilize an additional electrode (i.e., an auxiliary electrode) that designates a third potential between that of the active and return electrodes.Type: ApplicationFiled: January 13, 2015Publication date: July 16, 2015Applicant: ElectroMedical Associates LLCInventors: Yuval CARMEL, Anatoly SHKVARUNETS, Robert A.

Publication number: 20140081256Abstract: In contrast to instruments of the prior art that require bulky, cumbersome and/or costly electrical connections and energy sources, instruments designed in accordance with the instant disclosure are both portable and self-powered. The electrosurgical instruments of the present invention are not limited to a particular use or construction and can be adapted for operation with or without a patient return electrode (sometimes referred to as return pad or plate), in dry or wet fields, in the presence of bodily fluids (such as blood saliva and more), electrically conductive or non-conductive fluids. They may further be optionally equipped or configured for irrigation and or aspiration of liquids, gases or cryogenics, either external, remote or on-board. The electrode component of the electrosurgical instrument of the present invention may be monopolar, bipolar, or multipolar and may optionally include one or more floating electrodes.Type: ApplicationFiled: September 12, 2013Publication date: March 20, 2014Applicant: ElectroMedical Associates LLCInventors: Yuval CARMEL, Anatoly Shkvarunets, Robert A.
