  • Publication number: 20200155307
    Abstract: This invention discloses a valved stent for implantation at a dysfunctional or diseased atrioventricular valvular annulus. The valved stent is expandable from a collapsed shape to an expanded shape for minimally invasive delivery and has a low profile at the atrial or superior aspect to achieve improved hemodynamics and offers the capability to fabricate replacement valves having large diameters, The invention also includes a delivery apparatus uniquely designed for implantation of the valved stent and offering the potential for controlled and precise placement of the valved stent at the atrioventricular annulus. The invention also includes methods for use of the above devices and for treating diseased atrioventricular valves.
