20120172982CARDIAC VALVE PROSTHESIS - A cardiac valve prosthesis includes a frame and a set of prosthetic valve leaflets supported by the frame. The frame defines a principal axis of the cardiac valve prosthesis and includes first and second annular elements expandable from a radially contracted state to a radially expanded state, a plurality of valve supports supporting the leaflets, and a plurality of connecting members. The valve supports are angularly spaced from one another about the principal axis of the cardiac valve prosthesis, and the connecting members extend between and connect the first and second annular elements. When the annular elements are in the radially expanded state each of the connecting members arches radially outward with respect to the annular elements and is configured to project into one of the Valsalva sinuses when implanted. The connecting members are angularly spaced from the valve supports about the principal axis.07-05-2012

The valve leaflets may be flexible (e.g., so-called tissue or synthetic leaflets) or mechanical.03-28-2013
20110015731Anatomically Approximate Prosthetic Mitral Valve - An anatomically approximate prosthetic heart valve includes dissimilar flexible leaflets, dissimilar commissures and/or a non-circular flow orifice. The heart valve may be implanted in the mitral position and have one larger leaflet oriented along the anterior aspect so as to mimic the natural anterior leaflet. Two other smaller leaflets extend around the posterior aspect of the valve. A basic structure providing peripheral support for the leaflets includes two taller commissures on both sides of the larger leaflet, with a third, smaller commissure between the other two leaflets. The larger leaflet may be thicker and/or stronger than the other two leaflets. The base structure defines a flow orifice intended to simulate the shape of the mitral annulus during the systolic phase. For example, the flow orifice may be elliptical. A relatively wide sewing ring has a contoured inflow end and is attached to the base structure in such a way that the valve can be implanted in an intra-atrial position and the taller commissures do not extend too far into the left ventricle, therefore avoiding injury to the ventricle.01-20-2011

The holder has a safety mechanism that prevents valve delivery before the rod is deployed. One embodiment automatically deploys the rod upon opening a storage jar. One embodiment permits a delivery handle to directly deploy the rod, while another uses a separate worm screw and coupling. A holder clip that attaches to a packaging sleeve may be formed of flexible members meshed together from which the heart valve and holder are easily pulled free to eliminate a step of decoupling the clip from the sleeve.11-15-2012
