Abstract: 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. 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 the 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 the resilient force.

Abstract: 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.

Abstract: The invention relates to an anastomotic device for joining one end of a graft vessel to a target vessel at an opening made in the wall thereof The anastomotic device comprises a tubular body on which an outer flange, which comes into contact with the outside of the wall of the target vessel around the opening, and an inner flange, which comes into contact with the inside of the wall of the target vessel around the opening, are arranged. The inner flange is made up of a number of arms which are able to move from an extended position, located in the extension of the tubular body, under the influence of a pretension into a position extending in the lateral direction with respect to the tubular body, after the pretension has been released, in order to form the inner flange.
