  • ARTIFICIAL VALVE
    Publication number: 20110153008
    Abstract: The invention relates to a valve endoprosthesis, characterised in that it substantially comprises an extensible stent or frame (1) made of several parts, i.e. an upper cylinder (11), a lower bearing portion (21) having the shape of a truncated cone and a maximum diameter higher than that of the aortic ring and decreasing down to the diameter of the extensible stent or frame (1) in the direction of the proximal end, and arches (31), the upper cylinder (11) being connected to the lower bearing portion (21) via mounts (41) and by a valve (2) connected to said stent (1) by stitches, staples or clips. The invention can particularly be used in the field of medicine, in particular in plastic surgery, and particularly in cardiac surgery, in particular for cardiac prostheses.
