Described herein is a prosthetic valve device having an optimized valve component for durability and functionality of the collapsible leaflets. Specially designed commissures contribute to the optimization along with identified parameters. In other embodiments, the invention is a frame formed from a unique cutting pattern.

主权项

1. A commissure for anchoring a valve component of a prosthetic valve device to a frame, comprising:
an elongated strip of pliable material; a valve component comprising an annular sleeve having an annular inner wall; and a fastening element;wherein a portion of the annular inner wall is cinched between opposing legs of the elongated strip of pliable material; andwherein the frame comprises:
a tubular body comprising an axis; a plurality of circumferentially spaced-apart axial posts; and a lattice structure comprising open cells extending between each of the axial posts; wherein the lattice structures and the axial posts are integrally formed as a unitary structure free of seams; and wherein the axial posts comprise axially elongated nodes.
