Publication number: 20150342731Abstract: A device for the tranavascular implantation and fixation of prosthetic heart valves having a self-expanding heart valve stent (10) with a prosthetic heart valve (11) at its proximal end is introducible into a patient's main artery. With the objective of optimizing such a device to the extent that the prosthetic heart valve (11) can be implanted into a patient in a minimally-invasive procedure, to ensure optimal positioning accuracy of the prosthesis (11) in the patient's ventricle, the device includes a self-expanding positioning stent (20) introducible into an aortic valve positioned within a patient. The positioning stent is configured separately from the heart valve stent (10) so that the two stents respectively interact in their expanded states such that the heart valve stent (10) is held by the positioning stent (2) in a position in the patient's aorta relative the heart valve predefinable by the positioning stent (20).Type: ApplicationFiled: May 11, 2015Publication date: December 3, 2015Inventors: Hans-Reiner FIGULLA, Markus FERRARI, Christoph DAMM

Publication number: 20140214153Abstract: A catheter is disclosed for the transvascular implantation of prosthetic heart valves, e.g., including self-expanding anchorage supports, to reduce the risk to the patient during the implantation. Accordingly, a prosthetic heart valve comprising anchorage supports is temporarily housed in a folded form in a cartridge-type unit during the implantation. The cartridge-type unit can be fixed on the proximal end of a guide system, which comprises a flexible region that can be guided through the aorta. Actuating elements run through the interior of the hollow guide system, permitting sections of the cartridge-type unit to be displaced radially about their longitudinal axis and/or laterally in a proximal direction, thus allowing individual sections of the anchorage support and the associated prosthetic heart valve to be sequentially released.Type: ApplicationFiled: January 30, 2014Publication date: July 31, 2014Applicant: JENAVALVE TECHNOLOGY GMBHInventors: Rüdiger OTTMA, Robert MOSZNER, Hans-Reiner FIGULLA, Markus FERRARI, Christoph DAMM

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
