Patent ID: 8353955

Claim:
A prosthetic implant of the type comprising: a tubular support of axis X, which can be deformed between a compressed state with a small diameter and a dilated rest state with a larger diameter, the tubular support comprising a lattice comprising substantially rhombus-shaped meshes, each mesh having a first diagonal substantially parallel to the axis X and a second diagonal substantially perpendicular to the axis X, and at least one resilient membrane arranged inside the tubular support, comprising a portion which is fixed to fixing section delimited by a strand of the tubular support, said fixing section being oriented substantially parallel to the axis X, the at least one resilient membrane forming a plurality of leaves cooperating together to form an obturator, each leaf having a free downstream edge suitable for resting against one or more other free downstream edges of adjacent leaves to prevent the blood flow from circulating from downstream to upstream along the axis X, and for separating from the one or more free downstream edges to allow the blood flow to circulate in the upstream to downstream direction along the axis X, wherein at least one fixing mesh is a deformed mesh of which one of the segments forming its edges comprises the fixing section of the strand, the deformed mesh differing from the substantially rhombus shape of the meshes of the lattice and said segment of the deformed mesh having two points of curvature delimiting between them the fixing section.
