The frame (1) further includes at least two radially spaced commissure attachment regions (10, 10?, 10?) and a cell structure (30), composed of a plurality of lattice cells being arranged radially around a flow axis of the frame (1) and connecting the at least two commissure attachment regions (10, 10?, 10?). Finally, at least one anchoring/positioning arch (20, 20?, 20?) is provided, wherein said at least one anchoring/positioning arch (20, 20?, 20?) radially overlaps the cell structure (30) at least partially.
Abstract: A method of placing an implant including a stent at a native heart valve site includes orienting an expandable body of the stent such that a first open end of the stent is upstream a second open end of the stent relative to a direction of blood flow through a native heart valve. The native heart valve includes native leaflets and an annulus. The method also includes radially expanding a plurality of positioning arches positioned around an outer perimeter of the expandable body. The method additionally includes inserting the plurality of positioning arches respectively within a plurality of pockets defined by leaflets of the native heart valve and a heart structure from which the native leaflets extend.

Abstract: 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).

Abstract: The present invention relates to a stent (10) for the positioning and anchoring of a valvular prosthesis (100) in an implantation site in the heart of a patient. Specifically, the present invention relates to an expandable stent for an endoprosthesis used in the treatment of a narrowing of a cardiac valve and/or a cardiac valve insufficiency. So as to ensure that no longitudinal displacement of a valvular prosthesis (100) fastened to a stent (10) will occur relative the stent (10) in the implanted state of the stent (10), even given the peristaltic motion of the heart, the stent (10) according to the invention comprises at least one fastening portion (11) via which the valvular prosthesis (100) is connectable to the stent (10). The stent (10) further comprises positioning arches (15) and retaining arches (16), whereby at least one positioning arch (15) is connected to at least one retaining arch (16) via a first connecting land (17).

Abstract: 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.
