Patent number: 7422588Abstract: An electrocautery device is disclosed. In accordance with one aspect of the invention, the electrocautery electrode/tip is provided with a hollow, conductive tube terminating at its distal end in a ball point type tip. Fluid, preferably conductive fluid, is applied to the proximal end of the hollow electrode/tip, and expelled from the distal end thereof during electrocautery.

In addition, the conductive fluid expelled from the distal tip further lubricates the distal tip as it moves across the tissue. If conductive fluid is used, the conductive fluid emanating from the electrode/tip conducts the RF electrocautery energy away from the distal tip so that it is primarily the fluid, rather than the distal tip that actually accomplishes the cauterizing of tissue.Type: GrantFiled: December 7, 2006Date of Patent: September 9, 2008Assignee: Medtronic, Inc.Inventors: Peter M.

Between the underperfused regions and the oxygenated blood source, a target area is selected where thermal or mechanical injury is introduced, and optionally reintroduced, to convert initial capillary blush, resulting from the injury.Type: GrantFiled: April 12, 2004Date of Patent: June 24, 2008Assignee: Boston Scientific Scimed, Inc.Inventors: Richard L. Mueller, U. Hiram Chee

Publication number: 20080132970Abstract: A system and method is provided for the implantation and treatment of pain, such as scrotal and/or testicular pain, using electrical stimulation. The implanted portion of the system includes an implantable pulse generator that provides an electrical current through an implantable lead that extends to at least one electrode or an electrode array. The electrode is implanted into the relatively fragile tissue of the scrotal sac using a method that eliminates or otherwise minimizes damage to the tissue of the scrotal sac during the implantation procedure. An embodiment of the invention allows in-place testing of the electrode while the sheath still covers the implantable lead.Type: ApplicationFiled: December 5, 2006Publication date: June 5, 2008Inventor: Giancarlo Barolat

Patent number: 7364579Abstract: An electrocautery device is disclosed. In accordance with one aspect of the invention, the electrocautery electrode/tip is provided with a hollow, conductive tube terminating at its distal end in a ball point type tip. Fluid, preferably conductive fluid, is applied to the proximal end of the hollow electode/tip, and expelled from the distal end thereof during electrocautery. The ball point distal tip allows the distal tip to be directly applied to the tissue and “rolled” or slid along the tissue. This allows the distal tip to be moved across the tissue without dragging or snagging on the tissue. In addition, the conductive fluid expelled from the distal tip further lubricates the distal tip as it moves across the tissue. If conductive fluid is used, the conductive fluid emanating from the electrode/tip conducts the RF electrocautery energy away from the distal tip so that it is primarily the fluid, rather than the distal tip that actually accomplishes the cauterizing of tissue.Type: GrantFiled: January 23, 2007Date of Patent: April 29, 2008Assignee: Medtronic, Inc.Inventors: Peter M. J. Mulier, Michael F. Hoey

Patent number: 7364546Abstract: The present invention provides multi-functional medical catheters, systems and methods for their use. In one particular embodiment, a medical catheter (100) includes a flexible elongate body (105) having a proximal end (110) and a distal end (120). A plurality of spaced apart electrodes (130-136) are operably attached to the flexible body near the distal end. At least some of the electrodes are adapted for mapping a tissue and, in some embodiments, at least one of the electrodes is adapted for ablating a desired portion of the tissue. The catheter includes a plurality of tissue orientation detectors (140-146) disposed between at least some of the electrodes. In this manner, the medical catheter is capable of tissue mapping, tissue imaging, tissue orientation, and/or tissue treatment functions.Type: GrantFiled: March 19, 2007Date of Patent: April 29, 2008Assignee: Boston Scientific SciMed, Inc.Inventors: Dorin Panescu, David K. Swanson

Publication number: 20080097557Abstract: Implant apparatus and method for effecting a controlled heating of tissue within the region of dermis of skin. The heater implants are configured with a thermally insulative generally flat support functioning as a thermal barrier. One surface of this thermal barrier carries one or more electrodes within a radiofrequency excitable circuit as well as an associated temperature sensing circuit. The implants are located within heating channels at the interface between skin dermis and the next adjacent subcutaneous tissue layer such that the electrodes are contactable with the lower region of dermis. During therapy a conformal heat sink is positioned against the skin above the implants and a slight tamponade is applied through the heat sink to assure uniform dermis contact with electrode surfaces. An adjuvant may be employed to infiltrate dermis to significantly lower the thermal threshold transition temperature for dermis or dermis component shrinkage.Type: ApplicationFiled: October 19, 2006Publication date: April 24, 2008Applicant: Apsara Medical CorporationInventors: Philip E. Eggers, Andrew R. Eggers, Eric A. Eggers

Patent number: 7357798Abstract: The present invention provides systems and methods for selectively applying electrical energy to a target location within a patient's body, particularly including tissue in the spine. The present invention applies high frequency (RF) electrical energy to one or more electrode terminals in the presence of electrically conductive fluid or saline-rich tissue to contract collagen fibers within the tissue structures. In one aspect of the invention, a system and method is provided for contracting a portion of the nucleus pulposus of a vertebral disc by applying a high frequency voltage between an active electrode and a return electrode within the portion of the nucleus pulposus, where contraction of the portion of nucleus pulposus inhibits migration of the portion nucleus pulposus through the fissure.Type: GrantFiled: May 13, 2003Date of Patent: April 15, 2008Assignee: ArthroCare CorporationInventors: Lewis Sharps, David C. Hovda, Brian Martini, Maria Ellsberry
