Patent number: 8663338Abstract: Methods, devices and systems facilitate intermittent and/or partial obstruction of a pyloric valve. Devices generally include a support portion for preventing the device from passing through the pyloric valve and a tissue engagement portion for contacting tissue adjacent the pyloric valve to obstruct the valve. Some embodiments also include a positioning member extending from the tissue engagement portion for helping position the device for obstructing the valve. A retaining member may optionally be included on the distal end of the positioning member for further maintaining a position of the device in the stomach. Some embodiments are deliverable into the stomach through the esophagus, either by swallowing or through a delivery tube or catheter. Some embodiments are fully reversible. Some embodiments self-expand within the stomach, while others are inflated or otherwise expanded.Type: GrantFiled: January 9, 2009Date of Patent: March 4, 2014Assignee: BAROnova, Inc.Inventors: Daniel Rogers Burnett, Gregory W. Hall, Roxanne Richman, David A. Gallup, Annette Campbell-White

Publication number: 20070293854Abstract: A control system alters one or more characteristics of an ablating element to ablate tissue. In one aspect, the control system delivers energy nearer to the surface of the tissue by changing the frequency or power. In another aspect, the ablating element delivers focused ultrasound which is focused in at least one dimension. The ablating device may also have a number of ablating elements with different characteristics such as focal length.Type: ApplicationFiled: August 9, 2007Publication date: December 20, 2007Inventors: Benjamin PLESS, Scott Anderson, Jonathan Podmore, Matthias Vaska, John Crowe, Roxanne Richman, Timothy Ciciarelli, David Gallup, Jack Ulstad

Publication number: 20070255276Abstract: An ablating device has a cover which holds an interface material such as a gel. The cover contains the interface material during initial placement of the device. The ablating device may also have a removable tip or a membrane filled with fluid. In still another aspect, the ablating device may be submerged in liquid during operation.Type: ApplicationFiled: April 16, 2007Publication date: November 1, 2007Inventors: John Sliwa, Matthias Vaska, Jonathan Podmore, Roxanne Richman, Scott Anderson, Gerard Champsaur, John Crowe

Publication number: 20070050032Abstract: Prosthetic intervertebral discs, systems including such prosthetic intervertebral discs, and methods for using the same are described. The subject prosthetic discs include upper and lower endplates separated by a compressible core member. The subject prosthetic discs exhibit stiffness in the vertical direction, torsional stiffness, bending stiffness in the saggital plane, and bending stiffness in the front plane, where the degree of these features can be controlled independently by adjusting the components, construction, and other features of the discs.Type: ApplicationFiled: September 1, 2005Publication date: March 1, 2007Inventors: Darin Gittings, Michael Reo, Janine Robinson, John Ashley, Nicholas Koske, Roxanne Richman, Elizabeth Wistrom, Uriel Chee
