The electrode element may be created by forming divisions (such as slits or slots) from a first end of an electrically conductive elongate member towards an opposing second end of the elongate member. Alternatively, the divisions can be formed from a first end of an electrically conductive sheet towards an opposing second end of the sheet, and then bent or rolled to form the elongate member. In either case, the common electrode base can either be separately mounted to a probe shaft, or the probe shaft can be formed from the elongate member, in which case, the electrode base will be integrated with the probe shaft as a unibody structure. The electrode tines can be optionally shaped, e.g.Type: GrantFiled: July 19, 2010Date of Patent: April 16, 2013Assignee: Boston Scientific Scimed, Inc.Inventors: Jeff W.

Patent number: 8409194Abstract: A spinal surgical system comprising a plurality of surgical components for cooperating with a electrosurgical handpiece comprising an elongated tubular member housing an electrode, with the tubular member configured to fit within and be extended down a standard sized cannula in a MIS procedure. The system components comprise one or more cannulas, straight or beveled; one or more guide wires, with and without pointed ends for piercing tissue; a tapered dilator; a trephine; and one or more depth control stops for mounting on the cannula for monitoring its depth. The system is especially useful for performing a discectomy.Type: GrantFiled: July 5, 2011Date of Patent: April 2, 2013Inventor: Alan Ellman

Patent number: 8401667Abstract: Methods and systems for heating a body tissue region adjacent a body lumen using selective accumulation of energy without knowledge of tissue topography. Methods include positioning an energy delivery portion of a catheter within the lumen adjacent the body tissue region, determining a pulse characteristic in response to a thermal property of a first tissue type and applying pulsed energy with the characteristic to treat a second tissue type within the region by drawing heat from the first tissue at a rate that inhibits thermal damage to the first tissue while building-up heat in the second tissue. Systems include a catheter body having an energy delivery portion processor configured to control a pulse characteristic of pulsed energy to therapeutically treat the second tissue by drawing heat from the first tissue at a rate that inhibits thermal damage to the first tissue while building-up heat in the second tissue.Type: GrantFiled: November 12, 2009Date of Patent: March 19, 2013Assignee: Vessix Vascular, Inc.Inventors: Rolfe Tyson Gustus, Linas Kunstmanas, Arthur G.

Patent number: 8388618Abstract: The use of non-thermal plasma to treat mucus membrane bleeding is described herein. A non-thermal plasma is generated using an apparatus having a first electrode that receives alternating electrical potentials from a power supply. When placed in an appropriate location proximate to tissue, a non-thermal plasma is generated, the second electrode being human tissue, blood, etc. To reduce the likelihood of an arc being generated, potentially causing tissue damage or pain, the first electrode is partially encapsulated by a dielectric. The non-thermal plasma is applied to the area of bleeding for treatment.Type: GrantFiled: July 18, 2008Date of Patent: March 5, 2013Assignees: Drexel University, Philadelphia Health & Education CorporationInventors: Gregory Fridman, Alexander Fridman, Alexander F. Gutsol, Gennady Friedman, David Staack, Richard J. Hamilton

Publication number: 20130041436Abstract: A method and apparatus for treating masses, such as prostate or breast cancer, or any other soft tissue cancerous or benign mass, employs a unique, three-dimensional software-controlled electronic amplifier array using arbitrary waveforms that dynamically and proportionally steer electrical currents by using two or more current vector paths, sequentially or simultaneously, through a mass containing electrically-conductive ionic solutions so as to obtain 100% thermal heating or hyperthermia through the mass, and destroying it with a minimally-invasive treatment which requires no radiation or chemotherapy which could be harmful to the patient.Type: ApplicationFiled: August 8, 2012Publication date: February 14, 2013Inventors: RICHARD B.

Patent number: 8361067Abstract: 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 systems may include energy delivery probes and bone channeling instruments.Type: GrantFiled: September 12, 2012Date of Patent: January 29, 2013Assignee: Relievant Medsystems, Inc.Inventors: Richard Pellegrino, Paula Papineau, John S.
