Patent number: RE45130Abstract: 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.Type: GrantFiled: June 26, 2008Date of Patent: September 9, 2014Assignee: JenaValve Technology GmbHInventors: Hans-Reiner Figulla, Markus Ferrari, Carsten Weber, Thomas Peschel, Christoph Damm
