    摘要: The implant has an annularly bent base, whereby the imagined surface enclosed by the base is bent. Preferably the surface enclosed by the base is a symmetrical. It is particularly advantageous if the base is enclosed by a solid material and this is enclosed by a relatively soft material. This offers the possibility of designing fastening clips in the relatively solid material. Such implants are especially suited as heart valve rings.

    摘要: In a cardiac assist device, a housing has an inlet and outlet connectable to a patient's cardiovascular system. A pump is located within the housing to force blood that has entered through the inlet out through the outlet. The pump is connectable between the patient's left atrium and the aorta so as to assist the function of the left ventricle. A motor unit is also disposed within the housing, hermetically sealed from the pump. The whole unit is wholly implantable in a patient's chest. Permanently sealable valves, disposed in the inlet and outlet, may be closed without any invasive procedure to isolate the device from the heart once cardiac function assist is no longer required. The device may remain implanted within the patient indefinitely after the valves have been closed, and there is no requirement for a surgical procedure to remove the device once it is de-activated.

    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: 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.
