Patent number: 10660751Abstract: Apparatus for use at a native atrioventricular valve of a heart of a subject includes a prosthetic valve structure. The prosthetic valve structure comprises a valve ring, a leaflet frame, a plurality of prosthetic leaflets, and an upper skirt. The valve ring circumscribes a longitudinal axis of the prosthetic valve structure. The leaflet frame is disposed within the valve ring. The prosthetic leaflets are coupled to the leaflet frame, and are configured to facilitate upstream-to-downstream bloodflow longitudinally through the prosthetic valve structure. The upper skirt includes an annular skirt fabric, and an annular skirt frame coupled to the valve ring by the skirt fabric. The upper skirt extends radially outward and in an upstream direction from the valve ring. The upper skirt is configured to rest against an atrial portion of the native atrioventricular valve. Other embodiments are also described.Type: GrantFiled: August 6, 2019Date of Patent: May 26, 2020Assignee: CARDIOVALVE LTD.Inventor: Gil Hacohen

Patent number: 10226329Abstract: An artificial valve (5; 10; 20; 30; 50) for implantation in a mammal body, in or adjacent to a blood vessel, comprising a casing (12; 37; 61) and a closing mechanism. Part of the closing mechanism is a moving part (11; 21, 22; 31, 32, 33; 51) adapted to make movements to assume an open and a closed position for opening and closing of the blood vessel and positions between said open and closed positions, the closing mechanism (11; 21, 22; 31, 32, 33; 51) is adapted to let the moving part initiate and carry out its movements when a predefined threshold value is reached by a physical parameter of the mammal or a functional parameter of a device (8) used by the mammal. The closing mechanism is arranged to power at least one of said movements of the moving part (51) and to let a movement of the moving part take place passively.Type: GrantFiled: October 12, 2009Date of Patent: March 12, 2019Inventor: Peter Forsell

Patent number: 7896913Abstract: The invention relates to an anchoring system for heart valve prostheses which can be implanted by introduction via the aorta without any major surgical operation. With the heart valve prosthesis according to the invention it shall be achieved that this can be safely and quickly guided through the aorta toward the heart, and can be fixed there. With this, hook-shaped elements are secured to the commissures of the heart valve prosthesis the hooks of which are guided in an outward direction through the heart valve prosthesis material.Type: GrantFiled: September 5, 2006Date of Patent: March 1, 2011Assignee: JenaValve Technology, Inc.Inventors: Christoph Damm, Carsten Weber, Stefan Risse, Volker Guyenot, Matthias Mohaupt, Gerd Harnisch, Peggy Dorrer, Markus Ferrari, Klaus Lang, Hans-Reiner Figulla

Publication number: 20110029072Abstract: A heart valve prosthesis can include a supported valve including a biological valve portion mounted within a support structure. The supported valve is configured to provide for substantially unidirectional flow of blood through the supported valve. The supported valve has inflow and outflow ends that are spaced axially apart from each other. A fixation support member includes inflow and outflow portions. The inflow portion of the fixation support member extends from a radially inner contact surface of the fixation support member radially outwardly and axially in a direction of the inflow end of the supported valve. The outflow portion of the fixation support member extends from the radially inner contact surface radially outwardly and axially in a direction away from the inflow portion of the fixation support member. The radially inner contact surface is attached to a radially outer surface of the supported valve adjacent the inflow end of the supported valve.Type: ApplicationFiled: August 3, 2009Publication date: February 3, 2011Inventor: Shlomo Gabbay

Patent number: 7311730Abstract: An apparatus is disclosed for supporting a heart valve at an annulus of an implantation site. The apparatus includes a base portion operative to maintain a circumferential dimension thereof. A plurality of fingers extend axially and radially outwardly from the first end of the support element. A heart valve can be located within the apparatus to provide a prosthesis that can be suturelessly implanted at an annulus of a patient.Type: GrantFiled: February 13, 2004Date of Patent: December 25, 2007Inventor: Shlomo Gabbay

Patent number: 6569197Abstract: The present invention relates to a heart valve prosthesis having an annular body with a pair of flanges, and a closing element in the form of two or three flaps mounted through bearings into the body's recesses with freedom to be rotated. The annular body has a constant height on a greater portion of a ring circle, and a number of ledges equal to that of the flaps. The ledges are provided with flap rotation limiters. The flaps have ascending and descending surfaces oriented to the direct and reverse flow of blood, a side edge and an edge for joining the other flap. The descending surface of a flap is flat and the ascending surface thereof is spherically concave. The flaps have the minimal thickness on an axis of symmetry at the joining edge. The axes of rotation of the three flap embodiment are arranged relative to each other at an angle of 60° thereby to form the sides of an equilateral triangle. For the valve with two flaps the flange facing the direct flow of blood is thickened.Type: GrantFiled: June 27, 2001Date of Patent: May 27, 2003Inventors: Alexandr Vasilievich Samkov, Naum Abramovich Iofis, Andrej Vasilievich Agafonov

Patent number: 6228112Abstract: A prosthesis for use in a human heart as a valve that reduces or eliminates blood stagnation, and therefore, the possibility of thrombosis while increasing available blood flow area through the artificial heart valve without using hinges which can become inoperable due to interaction with blood and human tissue. The artificial heart valve includes a supporting ring, a pair of radially-disposed supporting arms having specially designed and support heads of a particular shape and a pair of semi-circular valve plates that hang from the support arm and engage the support arm heads. The valve plates each include a specially designed slot that receives the support arm head which allows movement of each of the valve plates during operation of the valve to prevent accumulation of human tissue from blocking the operation of the valve.Type: GrantFiled: May 14, 1999Date of Patent: May 8, 2001Inventors: Jack Klootz, Brian W.
