    • A thin-film transcatheter heart valve includes a stent support structure extending along a longitudinal axis and having a circular cross-section and a fenestrated thin-film mesh cover having a circular cross-section and attached to the stent support structure. The thin-film transcatheter heart valve may further include a bioprosthetic valve and/or a polymer outer covering. The fenestrated thin-film mesh cover may be formed by deep reactive ion etching a pattern of grooves on a surface of a substrate, the grooves corresponding to fenestrations in a desired Nitinol structure, depositing a lift-off layer on the grooved substrate surface, depositing a first Nitinol layer over the lift-off layer, lifting off the fenestrated thin-film sheet by etching, wherein the etching removes the lift-off layer, and expanding the fenestrated thin-film sheet to expand the fenestrations.
    • 薄膜经导管心脏瓣膜包括沿着纵向轴线延伸并具有圆形横截面的支架支撑结构以及具有圆形横截面并且附接到该孔的开窗薄膜网罩, 支架支撑结构。 薄膜经导管心脏瓣膜可进一步包括生物人造瓣膜和/或聚合物外覆层。 有孔薄膜网罩可以通过深反应离子蚀刻在衬底表面上的凹槽图案来形成,所述凹槽对应于期望的镍钛诺结构中的窗孔,在带槽衬底表面上沉积剥离层,沉积 在剥离层上方的第一镍钛诺层,通过蚀刻剥离开窗薄膜片,其中蚀刻除去剥离层,并且扩张开窗薄膜片以扩展开窗。
