  • Publication number: 20240115375
    Abstract: A prosthetic heart valve includes an annular frame that is radially collapsible and expandable between a radially collapsed configuration and a radially expanded configuration. The frame has a plurality of circumferentially extending rows of angled struts, each row of angled struts comprising angled struts arranged in a zig-zag pattern. The prosthetic heart valve further includes a leaflet structure positioned within the frame and secured thereto, and an outer sealing member mounted outside of the frame. The sealing member has an undulating outflow edge portion forming a plurality of triangular projections that are connected to and shaped to correspond to the zig-zag pattern of one of the rows of angled struts. The outer sealing member is sized to fit snugly against the outer surface of the frame when the frame is in the expanded configuration.

  • Patent number: 9472451
    Abstract: Semiconductor package device, such as wafer-level package semiconductor devices, are described that have pillars for providing electrical interconnectivity. In an implementation, the wafer-level package devices include an integrated circuit chip having at least one pillar formed over the integrated circuit chip. The pillar is configured to provide electrical interconnectivity with the integrated circuit chip. The wafer-level package device also includes an encapsulation structure configured to support the pillar.
