Patent number: 7758537Abstract: The present invention provides systems, apparatus and methods for removing the outer layer, or stratum corneum, of a patient's skin. In one aspect of the invention, a method includes positioning an active electrode adjacent to or near a target site on a patient's outer skin, and applying a sufficient high frequency voltage to the active electrode to remove the stratum corneum without removing the entire epidermis layer. In this manner, the present invention removes dead and/or damaged skin cells on the surface of the skin which improves the overall appearance of the skin. In addition, this process helps to stimulate the bodies own rejuvenation process. In some embodiments, this rejuvenation process occurs by the actual removal of the stratum corneum, which accelerates the regrowth of new cell layers in the skin. In other embodiments, thermal energy is applied to the underlying epidermis and/or dermis to stimulate the growth of new collagen.Type: GrantFiled: April 16, 1999Date of Patent: July 20, 2010Assignee: ArthroCare CorporationInventors: Stephen M. Brunell, Jean Woloszko, Michael A. Baker, Hira V. Thapliyal, Philip E. Eggers

Patent number: 7678069Abstract: Systems and methods are provided for applying a high frequency voltage in the presence of an electrically conductive fluid to create a relatively low-temperature plasma for ablation of tissue adjacent to, or in contact with, the plasma. In one embodiment, an electrosurgical probe or catheter is positioned adjacent the target site so that one or more active electrode(s) are brought into contact with, or close proximity to, a target tissue in the presence of electrically conductive fluid. High frequency voltage is then applied between the electrode terminal(s) and one or more return electrode(s) to generate a plasma adjacent to the active electrode(s), and to volumetrically remove or ablate at least a portion of the target tissue. The high frequency voltage generates electric fields around the active electrode(s) with sufficient energy to ionize the conductive fluid adjacent to the active electrode(s).Type: GrantFiled: June 2, 2000Date of Patent: March 16, 2010Assignee: ArthroCare CorporationInventors: Michael A. Baker, Stephen M. Brunell, Jean Woloszko, Ronald A. Underwood, Hira V. Thapliyal, Philip E. Eggers

Patent number: 6896672Abstract: Systems and methods are provided for removing fatty tissue underlying a patient's epidermis (e.g., blepharoplasty, brow lifts, eyelid shortening procedures, and the like). These methods include positioning one or more active electrode(s) and one or more return electrode(s) in close proximity to a target site on an external body surface of the patient. A high frequency voltage difference is applied between the active and return electrode(s), and the active electrode(s) are translated across the external body surface to create an incision therein. The bipolar configuration controls the flow of current to within and around the distal end of the probe, which minimizes tissue necrosis and the conduction of current through unwanted paths in the patient. The residual heat from the electrical energy also provides simultaneous hemostasis of severed blood vessels, which increases visualization and improves recovery time for the patient.Type: GrantFiled: May 1, 2000Date of Patent: May 24, 2005Assignee: Arthrocare CorporationInventors: Andrew R. Eggers, Philip E. Eggers, Ronald A. Underwood, Stephen M. Brunell, Hira V. Thapliyal

Patent number: 6719754Abstract: Systems and methods are provided for removing adipose or fatty tissue underlying a patient's epidermis is disclosed (e.g., liposuction, abdominoplasty, and the like). The method includes positioning one or more active electrode(s) and one or more return electrode(s) in close proximity to a target region of fatty tissue. A high frequency voltage difference is applied between the active and return electrodes, and the fatty tissue or fragments of the fatty tissue are aspirated from the target region. The high frequency voltage either softens the fatty tissue or completely removes at least a portion of the tissue. In both embodiments, the remaining fatty tissue is more readily detached from the adjacent tissue in the absence of energy, and less mechanical force is required for removal. The bipolar configuration of the present invention controls the flow of current to the immediate region around the distal end of the probe, which minimizes tissue necrosis and the conduction of current through the patient.Type: GrantFiled: April 9, 2002Date of Patent: April 13, 2004Assignee: ArthroCare CorporationInventors: Ronald A. Underwood, Stephen M. Brunell, Michael A. Baker, Hira V. Thapliyal, Philip E. Eggers

Patent number: 6461354Abstract: Systems and methods are provided for selectively applying electrical energy to a target location on an external body surface, such as skin tissue removal and/or collagen shrinkage in the epidermis or dermis, e.g., the removal of pigmentations, vascular lesions (e.g., leg veins), scars, tattoos, etc., and for other surgical procedures on the skin, such as tissue rejuvenation, cosmetic surgery, wrinkle removal, hair removal and/or transplant procedures. The present invention applies high frequency (RF) electrical energy to one or more electrode terminals adjacent an external body surface, such as the outer surface of the skin, to remove and/or modify the structure of tissue structures within the skin. Depending on the specific cosmetic procedure, the present invention may be used to: (1) volumetrically remove tissue or hair (i.e.Type: GrantFiled: May 18, 1999Date of Patent: October 8, 2002Assignee: ArthroCare CorporationInventors: Phillip M.

Publication number: 20010029373Abstract: Systems and methods are provided for treating a discolored blood vessel in tissue under the surface of the skin. In this method, one or more active electrode(s) are positioned in close proximity to a target region of the blood vessel, and a sufficient high frequency voltage is applied to the electrode terminal(s) to cause thermal damage to a target region within the blood vessel. The thermal injury causes the vessel to shrink or to thrombose and collapse so that blood flow through the vessel is restricted or completely interrupted. Preferably, the vessel is injured with minimal thermal energy being applied to the surrounding tissue, which prevents the tissue discoloration or scarring associated with prior art thermal processes. The electrode terminal(s) may be positioned on the external surface of the skin, or they may be introduced through a percutaneous penetration in the outer skin surface to the blood vessel.Type: ApplicationFiled: January 30, 2001Publication date: October 11, 2001Applicant: ArthroCare CorporationInventors: Michael A.
