    Abstract: An implantable prosthetic valve can comprise an annular frame comprising an inflow end and an outflow end and being radially collapsible and expandable between a radially collapsed configuration and a radially expanded configuration, the frame defining an axial direction extending from the inflow end to the outflow end, a leaflet structure positioned within the frame and secured thereto, and an annular outer skirt positioned around an outer surface of the frame, wherein the outer skirt comprises an inflow edge secured to the frame at a first location, an outflow edge comprising a plurality of alternating projections and notches, wherein the projections are secured to the frame at a second location, and the notches are not directly secured to the frame, an intermediate portion between the inflow edge and the outflow edge that comprises a plurality of openings.

    Abstract: An implantable prosthetic valve includes a radially collapsible and expandable annular frame having three commissure attachment posts and four rows of circumferential struts. The rows include a first row, a second row downstream of the first row, a third row downstream of the second row, and a fourth row downstream of the third row and defining an outflow end of the frame. Each row of circumferential struts includes angled struts arranged in a zig-zag pattern. A leaflet structure includes three leaflets forming three commissures, each commissure being connected to one of the commissure attachment posts only at locations along the commissure attachment posts between a first plane that is perpendicular to a longitudinal axis of the frame and intersects crowns of the third row of struts and a second plane that is perpendicular to the longitudinal axis and intersects crowns of the fourth row of struts.

    Abstract: Systems, dies, and methods are provided for processing pericardial tissue. The method includes positioning a die-cut assembly over the pericardial tissue, the die-cut assembly including a die having a plate, a the pattern, and an opening, the die pattern attached to the plate, the opening formed in the plate to provide access to the pericardial tissue, and measuring a thickness of the tissue through the opening. The die-cut assembly may be mounted for automated vertical movement, and a platen on which the tissue is placed is capable of automated horizontal movement. Different target areas on the tissue can be assessed by measuring the thickness through the die, and when an area is deemed suitable the die pattern cuts a shape therefrom. The system is useful for cutting uniform thickness heart valve leaflets, and can be automated to speed up the process.
