Publication number: 20100152818Abstract: A system for stimulation includes an implantable pulse generator, a lead, and conductors. The lead includes an array body disposed at a distal end of the lead and electrodes concentrically arranged on the array body. A center electrode may also be disposed on the array body. The electrodes may be arranged in more than one concentric ring. A method of using an implantable stimulator includes implanting an implantable stimulator and providing an electrical signal to at least one electrode of the implantable stimulator to stimulate a tissue. The electrical signal may be provided between diametrically opposed electrodes or between electrodes that are not diametrically opposed. If the implantable stimulator has a center electrode, the electrical signal may be provided between the center electrode and at least one concentrically arranged electrode.Type: ApplicationFiled: February 24, 2010Publication date: June 17, 2010Applicant: Boston Scientific Neuromodulation CorporationInventors: Meredith L. Anderson, Anne M. Pianca

Patent number: 7734348Abstract: Various embodiments of the present subject matter relate to a lead. Various lead embodiments comprise a lead body including a first portion, a first branch and a second branch. The first portion has an end adapted to connect to an implantable medical device. The first branch and the second branch is connected to the first portion at a bifurcated region. The first branch includes a distal end adapted to be fed into a right pulmonary artery and to securely position at least one electrode within the right pulmonary artery. The second branch includes a distal end adapted to be fed into a left pulmonary artery and to securely position at least one electrode within the left pulmonary artery. Other embodiments are provided herein.Type: GrantFiled: May 10, 2005Date of Patent: June 8, 2010Assignee: Cardiac Pacemakers, Inc.Inventors: Yongxing Zhang, Yunlong Zhang

Patent number: 7715921Abstract: As compared to conventional electrodes, the electrode configurations disclosed herein minimize irritation and damage to the skin when they are placed in contact with a patient's body over extended of time. The electrodes are formed from a conductive substrate coated with a thin dielectric material, and a plurality of open spaces pass through the electrodes. Those open spaces are distributed and sized to permit moisture on the surface of the patient's body to escape when the electrode is placed in contact with the patient's body. One intended use for the electrodes is for treating tumors by applying an AC electric field with specific frequency and field strength characteristics over an extended period of time.Type: GrantFiled: December 5, 2005Date of Patent: May 11, 2010Assignee: Standen Ltd.Inventor: Yoram Palti

Publication number: 20100076508Abstract: A neurostimulation lead or lead extension includes a lead body having a proximal end and a distal end. A plurality of first contacts are disposed on the distal end of the lead body. A plurality of second contacts are disposed on a proximal end of the lead body. A plurality of conductors extend along the lead body. Each of the plurality of conductors electrically couples at least one of the first contacts to at least one of the second contacts. At least one of the conductors includes at least one switch disposed along a length of the conductor. The at least one switch is configured and arranged to separate the conductor into a plurality of individual segments when the at least one switch is opened.Type: ApplicationFiled: September 25, 2008Publication date: March 25, 2010Applicant: Boston Scientific Neuromodulation CorporationInventors: Matthew Lee McDonald, Anne Margaret Pianca

Publication number: 20100070010Abstract: An electrostimulation device (e.g., 100) consists of a single paddle (e.g., 102) and at least one lead (e.g., 110) for connecting the electrostimulation device to a pulse generator. The paddle has at least one electrode (e.g., 106) for providing electrical stimulation. The electrode(s) is provided in an area (A) of the paddle and a ratio of the width of the area to the length of the area is greater than 0.5. The present invention also relates to a paddle (e.g., 102) implantable in a vertebra.Type: ApplicationFiled: March 7, 2007Publication date: March 18, 2010Inventor: Brian Arthur Simpson

Patent number: 7676275Abstract: A lead of the present invention comprises an electrode array adapted to be stably anchored at a selected location within the vena cava of a human patient. The electrode array may take various shapes, including helical, annular and linear. The electrode array is connectable to an electrical stimulation means such as an implantable pulse or signal generator. Electrical stimulation applied to a selected region of the vena cava and across the wall of the vein, that is, transvascularly, to the vagus nerve or branches thereof, depolarizes the nerve to thereby effect control of the heart rate.Type: GrantFiled: May 2, 2005Date of Patent: March 9, 2010Assignee: Pacesetter, Inc.Inventors: Taraneh Ghaffari Farazi, Timothy A.
