Abstract

Cette prothèse (1) comprend une armature tubulaire expansible (2) et une valve prothétique (3) montée sur cette armature. Selon l'invention : - la portion atriale (2a) est formée de trois ou quatre extensions (4) en fil métallique, régulièrement réparties sur la circonférence de cette portion atriale (2a) et se projetant depuis ladite portion annulaire (2i), chaque extension (4) étant formée d'un fil unique en U ou V inversé et les différentes extensions (4) étant sensiblement inscrites dans une sphère tronquée imaginaire placée au-dessus de ladite portion annulaire (2i) ; - ladite portion annulaire (2i) est formée de mailles en losange qui comprennent des pointes d'ancrage (5) ; et - ladite portion ventriculaire (2v) est formée de trois ou quatre extensions (6) homologues aux extensions (4), sensiblement inscrites dans une forme ovoïde imaginaire placée au-dessous de ladite portion annulaire (2i).This prosthesis (1) comprises an expandable tubular frame (2) and a prosthetic valve (3) mounted on this frame. According to the invention: - the atrial portion (2a) is formed of three or four extensions (4) of metal wire, regularly distributed over the circumference of this atrial portion (2a) and projecting from said annular portion (2i), each extension (4) being formed of a single inverted U or V-shaped wire and the various extensions (4) being substantially inscribed in an imaginary truncated sphere placed above said annular portion (2i); - Said annular portion (2i) is formed of diamond-shaped meshes which include anchoring points (5); and - said ventricular portion (2v) is formed of three or four extensions (6) homologous to the extensions (4), substantially inscribed in an imaginary ovoid shape placed below said annular portion (2i).
