摘要： The invention relates to an aortic cannula for delivering fluid, especially blood, into a vessel of the human body, particularly the aortic arch. Said aortic cannula comprises an elongate basic cannula body into which the fluid is directed, an orifice from which the fluid is discharged at the distal end of the basic cannula body in a basic direction of flow defined by the basic cannula body, as well as at least one first deflecting element and a second deflecting element that are disposed in front of the orifice within the flow path of the fluid. Said at least one deflecting element and said second deflecting element are respectively provided with a passage opening that is aligned relative to the orifice, and a deflecting area which redirects the portion of the fluid, which does not flow through the passage opening. The area of the passage opening of the first deflecting element is greater than area of the passage opening of the second deflecting element, and/or the angle of deflection of the deflection area of the first deflecting element is greater than the angle of deflection of the deflection area of the second deflecting element which is arranged behind the first deflecting element.

摘要： A prosthetic heart valve includes a valve frame (2), on which a plurality of valve leaflets (8) are fixed, and a fastening area for fastening in a blood vessel, which axially adjoins the valve frame (2). A stabilizing ring (14) is arranged in the fastening area. The stabilizing ring (14) defines a predetermined shape and a predetermined diameter of the fastening area and has at least one predetermined expansion point (22), whereby it is possible to expand the stabilizing ring (14) by an action of radial force on an inner circumference.

摘要： The invention relates to a textile vascular prosthesis (1) with a circulatory pleating formed by folds (4), and with an arch-shaped longitudinal flexion (2) extending over at least a partial section and formed by asymmetric shortening gathering of the prosthesis wall by means of at least one longitudinal seam (7) extending along the partial section. The at least one longitudinal seam gathers the prosthesis wall while preserving the accordion-like structure (4) and the compacted state of the pleating (4) in the longitudinal direction.

摘要： A heart valve prosthesis includes a downstream first axial end (6) and an upstream second axial end (8) and a stitching ring (10) extending in an arcuate manner for stitching in a blood vessel. The arcuate course of the stitching ring (10) is formed by three arcs (12) and three transition regions (14). At each end of two of the arcs (12) transition into each other. The stitching ring (10) has a movable tab (18) at at least one of the three transition regions (14). The movable tab (18) can be selectively directed toward the first axial end (6) or folded over toward the second axial end (8).
