    摘要： A valve prosthesis device (20) is disclosed suitable for implantation in body ducts. The device comprises a support stent (22), comprised of a deployable construction adapted to be initially crimped in a narrow configuration suitable for catheterization through the body duct to a target location and adapted to be deployed by exerting substantially radial forces from within by means of a deployment device (48) to a deployed state in the target location, and a valve assembly (28) comprising a flexible conduit having an inlet end (24) and an outlet (26), made of pliant material (29) attached to the support beams (23) providing collapsible slack portions of the conduit at the outlet. The support stent is provided with a plurality of longitudinally rigid support beams (23) of fixed length. When flow is allowed to pass through the valve prosthesis device from the inlet to the outlet, the valve assembly is kept in an open position, whereas a reverse flow is prevented as the collapsible slack portions of the valve assembly collapse inwardly providing blockage to the reverse flow.

    摘要： The invention relates to a cardiac prosthesis fixing device made up of a tubular element that can be accommodated inside a valve annulus of a heart and is provided with a bottom flange and top flange, between which the valve annulus can be accommodated. According to the invention the bottom flange is bent, or can be bent, reversibly, against a resilient force, from a first outward-pointing position into a second position in which the projection of the bottom flange on a radial transverse surface of the tubular element is located essentially on and/or within the periphery of the tubular element and the bottom flange is fixed or can be fixed in said second position in such a way that the fixing can be released in order to bend back the bottom flange towards the first position under the influence of said resilient force.

    摘要： The present invention provides a lumen support device (10), or stent, used to open or expand a body lumen. The stent (10) incorporates elongated parallel stent components (23) with circumferential members (20), fingers, which weave into paired slots (30) of an adjacent stent component. This weave-like interlocking configuration enables the stent (10) to expand radially without yielding or plastically deforming the material of which the stent is fabricated. The weave-like mechanism allows for uniform, smooth expansion without change in longitudinal dimensions for the complete assembly. Once assembled, the plurality of parallel elongated stent components form a cylindrical configuration.
