Patent number: 7896915Abstract: A medical device for treating a heart valve insufficiency, with an endoprosthesis which can be introduced into a patient's body and expanded to secure a heart valve prosthesis in the patient's aorta. In an embodiment, the endoprosthesis has at plurality of positioning arches configured to be positioned with respect to a patient's aorta and a plurality of retaining arches to support a heart valve prosthesis. The endoprosthesis includes a first collapsed mode during the process of introducing it into the patient's body and a second expanded mode when it is implanted.Type: GrantFiled: April 13, 2007Date of Patent: March 1, 2011Assignee: JenaValve Technology, Inc.Inventors: Volker Guyenot, Thomas Peschel, Christoph Damm, Hans-Reiner Figulla, Markus Ferrari, Johannes Jung

Patent number: 7892276Abstract: A valve for use in a body lumen, where the valve includes a valve leaflet with delayed leaflet deployment relative an in vivo implant time. The valve includes a valve frame, a valve leaflet coupled to the valve frame. The valve leaflet includes a commissure that can reversibly seal for unidirectional flow of a liquid through the valve, and a biodegradable adhesive between the valve leaflet and the valve frame to hold at least the commissure of the valve leaflet in a static relationship relative the valve frame for a predetermined time once implanted in vivo.Type: GrantFiled: December 21, 2007Date of Patent: February 22, 2011Assignee: Boston Scientific Scimed, Inc.Inventors: Patrick J. Stocker, Joseph C. Walker

Publication number: 20110029066Abstract: A stent valve insertable in a body vessel containing a body fluid. The stent valve includes: a valve for at least partially controlling the flow of the body fluid in the body vessel; and a scaffold, the scaffold including: an anchoring section for anchoring the scaffold to said body vessel and a valve supporting section supporting the valve. The scaffold is substantially radially expandable from a scaffold retracted configuration to a scaffold expanded configuration. The valve supporting section is expandable over a greater range of radial expansion than the anchoring section.Type: ApplicationFiled: June 24, 2010Publication date: February 3, 2011Inventors: Ran Gilad, Frank Baylis, Youssef Bisdillah

Publication number: 20110029067Abstract: A vascular device comprising a plurality of vessel engaging members and a valve. The device is movable from a collapsed insertion position having a first diameter to a second expanded position having a second diameter larger than the first diameter. The plurality of vessel engaging members extend outwardly from the device for securely engaging the internal wall of a vessel upon expansion of the device to the second expanded position, wherein the vessel engaging members pull the internal wall of the vessel radially inwardly upon movement of the device from the second expanded position toward a first expanded position having a third diameter greater than the first diameter and less than the second diameter. In the first expanded position the valve is movable between an open position to allow blood flow therethrough to a closed position to prevent blood flow.Type: ApplicationFiled: September 13, 2010Publication date: February 3, 2011Inventors: James F. McGuckin, JR., Peter W.J. Hinchliffe
