Patent number: 11207182Abstract: A heart valve therapeutic device (1) comprises a coaptation assist valve (20) comprising a conduit (2) with an outer surface (3) for coaption with the native leaflets, and a prosthetic flow valve (5) mounted within the conduit (2) to allow one-way flow through the conduit (2). Support for the coaptation assist valve (20) is provided by a support (10) for positioning the conduit (2) across the native leaflets, and connectors (15) attaching the conduit (2) to the support (10).Type: GrantFiled: March 18, 2021Date of Patent: December 28, 2021Assignee: The Provost Fellows, Foundation Scholars and the Other Members of Board, of the College of the Holy and Undivided Trinity of Queen Elizabeth, Near Dublin (TCD)Inventors: Paul Heneghan, Bruce Murphy, Lucy O'Keeffe, Martin Quinn, Conor Quinn

Patent number: 10987220Abstract: A heart valve therapeutic device (1) has an elongate anchor (7) wherein the anchor has a stiffness to hold its shape and location to support the valve element. The anchor may have a stylet or a shaped or stiff collar (70) arranged to provide a desired shape to the anchor (7) and it may be lockable. A prosthetic valve element (15) has leaflets (17) and is supported on the anchor by coupler (16, 50) at a desired location. There is an actuator for changing relative axial position of the proximal and distal couplers (16, 50) on the anchor. The anchor stiffness may be sufficient to provide sufficient support to resist axial forces from the ventricle in use without necessarily having a fixing element engaging heart tissue. The prosthetic leaflets (240) may extend proximally and radially outwardly, so that there is excellent co-apting of the native leaflets (NL) against the prosthetic leaflets (240).Type: GrantFiled: June 12, 2020Date of Patent: April 27, 2021Assignee: The Provost, Fellows Foundation Scholars, and the Other Members of the Board, Of The College of the Holy and Undivided Trinity of Queen Elizabeth Near Dublin (TCD)Inventor: Martin Quinn
