Device for fastening and anchoring cardiac valve prostheses

Abstract

The invention relates to a device for fastening and anchoring heart valve prostheses which is essentially formed of wire-shaped interconnected elements. According to the object such a device shall be able to be implanted through the aorta in a minimally invasive manner by folding up small enough, and deployed at the site of implantation, wherein a secure retention and a secure sealing with respect to the aorta wall are ensured. To solve this object, for fastening and anchoring a heart valve prosthesis three respective identical pairs of arched elements are interconnected by means of solid articulations in a respective configuration offset by 120° each. These solid articulations meet the function of pivot bearings.
