Patent number: 7736379Abstract: Apparatus & methods for optimizing anchoring force are described herein. In securing tissue folds, over-compression of the tissue directly underlying the anchors is avoided by utilizing tissue anchors having expandable arms configured to minimize contact area between the anchor and tissue.

The sealed contracting member is operable to be disposed within an interior space defined by the circumferential wall and coupled to at least of portion of the circumferential wall. When reduced pressure is provided to the sealed contracting member, the sealed contracting member contracts and the circumferential wall delivers a closing force. Other systems and methods are presented.Type: ApplicationFiled: May 15, 2009Publication date: April 29, 2010Inventors: Keith Patrick Heaton, Ian James Hardman, Christopher Guy Coward, Colin John Hall

Publication number: 20100106187Abstract: A modular, reduced-pressure, wound-closure system for providing a closing force on a surface would includes a flexible strap operable to be formed into a closed loop inbound and around the surface wound and a plurality of modular closing members coupled to the flexible strap. A reduced-pressure source is fluidly coupled to the plurality of modular closing members. The modular closing members are operable to generate a closing force on the surface wound. A portion of the modular closing members are releasably attached to the patient's epidermis proximate the surface wound and another portion are attached to the flexible strap. A reduced pressure from the reduced-pressure source is delivered to each modular closing member to generate the closing force on the surface wound. Methods and other systems are presented.Type: ApplicationFiled: May 15, 2009Publication date: April 29, 2010Inventors: Keith Patrick Heaton, Christopher Guy Coward, Colin John Hall

Publication number: 20100106186Abstract: A reduced-pressure, deep-tissue closure device for applying a closing force on a deep tissue includes a contractible matrix that is formed with a first plurality of apertures and which has a first side and a second, inward-facing side. The contractible matrix is for disposing proximate to the deep tissue. A reduced-pressure source is fluidly coupled to the contractible matrix and operable to deliver reduced pressure to the contractible matrix. When under reduced pressure, the contractible matrix grips the deep tissue adjacent the contractible matrix and provides a closing force on the deep tissue. A system and method are also presented.Type: ApplicationFiled: May 15, 2009Publication date: April 29, 2010Inventors: James Joseph Sealy, Keith Patrick Heaton, Colin John Hall, Christopher Guy Coward, Mark Stephen James Beard

Patent number: 7691128Abstract: Devices and methods for sealing a passageway formed by a patent foramen ovale (PFO track) in the heart are provided. One method includes providing an abrading device to the PFO track and abrading the tissue within the PFO track. The abraded tissue forming the PFO track is then held together under pressure, either via lowering right atrial pressure or via applying suction to the septum primum to pull it into apposition against the septum secundum. After a sufficient period of time, the pressure is released and the abraded tissue heals to form a robust seal over the PFO track. Additionally, several devices are provided which can be placed into the PFO track to apply adhesive to the walls of the PFO track. The devices may or may not be left within the PFO track. If the devices are not left within the PFO track, the walls of the PFO track, covered with adhesive, are brought into apposition with one another and adhered together.Type: GrantFiled: October 14, 2005Date of Patent: April 6, 2010Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: David J. Blaeser, Peter T. Keith, Jerome K. Grudem, Jr., Scott A. Olson, Steven S. Hackett, Thomas V. Ressemann, Joel D. Phillips, Mark R. Christianson, Dennis W. Wahr

Patent number: 7686829Abstract: A wound closure system and a method of closing a wound are disclosed. The disclosure is directed to a wound closure system comprising a skin anchor mechanically attached to external skin tissue on a first side of a generally linear wound, an anchorable tensioning apparatus mechanically attached to external skin tissue on an opposite side of the wound, and a line extending between the skin anchor and the tensioning apparatus to movably connect the anchor to the tensioning apparatus. The line is fixedly engaged with an anchor on one side of the wound while the tensioning apparatus provides tension on the line to draw the skin anchor and the tensioning apparatus toward each other and toward the wound.Type: GrantFiled: November 4, 2004Date of Patent: March 30, 2010Assignee: Wound Care Technologies, Inc.Inventors: Daniel M. Elliott, George M. Hoedeman, John J. Berkey, Paul J. Anderson, Robert C. Wilke

Patent number: 7683234Abstract: Devices, bandages, kits and methods are described that can control or regulate the mechanical environment of a wound to ameliorate scar and/or keloid formation. The mechanical environment of a wound includes stress, strain, and any combination of stress and strain. The control of a wound's mechanical environment can be active, passive, dynamic, or static. The devices are configured to be removably secured to a skin surface in proximity to the wound site and shield the wound from endogenous and/or exogenous stress.Type: GrantFiled: August 3, 2007Date of Patent: March 23, 2010Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Geoffrey C. Gurtner, Reinhold H. Dauskardt, Michael T. Longaker, Paul Yock

Patent number: 7678135Abstract: Apparatus & methods for optimizing anchoring force are described herein. In securing tissue folds, over-compression of the tissue directly underlying the anchors is avoided by utilizing tissue anchors having expandable arms configured to minimize contact area between the anchor and tissue. When the anchor is in its expanded configuration, a load is applied to the anchor until it is optimally configured to accommodate a range of deflections while the anchor itself exerts a substantially constant force against the tissue. Various devices, e.g., stops, spring members, fuses, strain gauges, etc., can be used to indicate when the anchor has been deflected to a predetermined level within the optimal range. Moreover, other factors to affect the anchor characteristics include, e.g., varying the number of arms or struts of the anchor, positioning of the arms, configuration of the arms, the length of the collars, etc.Type: GrantFiled: April 14, 2006Date of Patent: March 16, 2010Assignee: USGI Medical, Inc.Inventors: Tracy D.
