<p>A heart valve prosthesis, comprising a housing (1) having a projection (3) along its whole perimeter (2), an occluder (4) which restricts the blood backflow (I), and a cuff (5) made of fabric and having a mounting surface (6) which comes into contact with cardiac tissues (II), and an outer surface (7) which comes into contact with the blood flow. Inside the cuff (5) are located a stent (8) forming an opening (9) for installation of the prosthesis housing (1), a supporting element (10) and a retaining element (11) which fix the projection (3) of the housing (1) within the stent (8) of the cuff (5) forming a quick- dismountable junction of the housing (1) with the cuff (5). The retaining element (11) in the form of a ring has two cams (12) protruding above the outer surface (7) of the cuff (5) with a cut (13) in the zone between the cams (12).</p> |
