Prosthetic implant
First Claim
1. 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, andat 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.

Abstract
Prosthetic implant of the type comprising: a tubular support (12) of axis X, which can be deformed between a compressed state with a small diameter and a dilated state with a larger diameter, the tubular support comprising a lattice comprising rhombus-shaped meshes (26), each mesh having a first diagonal (28) parallel to the axis X and a second diagonal (32) perpendicular to the axis X; and at least one resilient membrane (14A, 14B) arranged inside the tubular support. The membrane comprises a fixing portion (48, 52), the fixing portion being fixed to a fixing section (65, 66) delimited by a strand (20A, 20B) of the tubular support, the fixing section being oriented substantially parallel to the axis X.

4. 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 tubular support comprising at least one thread intertwined so as to delimit said meshes, said strand is an additional thread intertwined between the threads forming the lattice, wherein said additional thread is shaped to comprise at least one substantially U-shaped hairpin section, located along the first diagonal of a mesh known as the fixing mesh, the branches of the hairpin forming first and second fixing sections, the first fixing section carrying a first fixing portion of a first leaf and the second fixing section carrying a second fixing portion of a second leaf adjacent to the first leaf, said first and second fixing portions being edge to edge.

5. 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 tubular support comprising at least one thread intertwined so as to delimit said meshes, said strand is an additional thread intertwined between the threads forming the lattice, wherein said additional thread is saw-tooth-shaped so as to have a first segment sloping relative to the axis X and a second segment parallel to the axis X, each second segment comprising a fixing section of a fixing portion of a leaf.
