Publication number: 20180021132Abstract: The invention relates to a catheter for the transvascular implantation of prosthetic heart valves, in particular comprising self-expanding anchorage supports (10), which allow a minimally invasive implantation of prosthetic heart valves. The aim of the invention is to reduce the risk to the patient during the implantation. To achieve this, according to the invention a prosthetic heart valve comprising anchorage supports is temporarily housed in a folded form in a cartridge-type unit (4) during the implantation. The cartridge-type unit can be fixed on the proximal end of a guide system (1), which comprises a flexible region (9) that can be guided through the aorta.Type: ApplicationFiled: September 11, 2017Publication date: January 25, 2018Applicant: JENAVALVE TECHNOLOGY, INC.Inventors: Rüdiger Ottma, Robert Moszner, Hans-Reiner Figulla, Markus Ferrari, Christoph Damm

Patent number: 9855142Abstract: A device for the transvascular 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 (20) in a position in the patient's aorta relative the heart valve predefinable by the positioning stent (20).Type: GrantFiled: June 28, 2016Date of Patent: January 2, 2018Assignee: JenaValve Technologies, Inc.Inventors: Hans-Reiner Figulla, Markus Ferrari, Christoph Damm

Patent number: 9775705Abstract: A catheter is described 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 with 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 includes 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: GrantFiled: January 30, 2014Date of Patent: October 3, 2017Assignee: JenaValve Technology, Inc.Inventors: Rüdiger Ottma, Robert Moszner, Hans-Reiner Figulla, Markus Ferrari, Christoph Damm

Patent number: RE46705Abstract: A self-expanding occlusion device for occluding an atrial auricula in the heart of a patient includes a braiding of thin wires or threads given a suitable profile form by means of a molding and heat treatment procedure. The occlusion device includes a proximal retention area, a distal retention area and a center section. The occlusion device holds securely in the atrial auricula of a patient in its expanded and implanted state without damaging the tissue of the patient's heart. The proximal retention area has a flanged area which positions at the inner walls of the atrial auricula when the occlusion device is in an expanded state in the atrial auricula to be occluded, and forms a force-fit connection with the inner walls of the atrial auricula, thus holding the implanted and expanded occlusion device in the atrial auricula, whereby the distal retention area closes the opening in the atrial auricula.Type: GrantFiled: January 24, 2014Date of Patent: February 13, 2018Assignee: Occlutech Holding AGInventors: Hans Reiner Figulla, Friedrich Moszner, Robert Moszner, Rüdiger Ottma, Christopf Damm, Susann Klebon
