Abstract

This invention relates to a device for fastening and anchoring heart valve prostheses which is essentially formed of wire-shaped interconnected elements. The aim of the invention is to be able to be implant, in a minimally invasive manner, a device of this type via the aorta by compressing the device to make it smaller, and by extending the same at the site of implantation, whereby ensuring a secure retention and a secure sealing with regard to the aorta wall. To this end, the invention provides that for fastening and supporting a cardiac valve prosthesis, three identical pairs of arched elements are interconnected, with a configuration that is offset by 120°, by means of solid body articulations. These solid body articulations carry out the function of pivot bearings.
