Radially collapsible frame for a prosthetic valve and method for manufacturing such a frame

Abstract

The present invention relates to a radially collapsible frame (1) for a prosthetic valve, the frame (1) comprising an outflow end region (3) at a proximal end of the frame (1) and an inflow end region (2) at a distal end of the frame (1), opposite to the outflow end region (3). 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. In order to form the inventive frame from as a single piece, the invention further relates to a method comprising bending the at least one anchoring/positioning arch (20, 20′, 20″) towards the cell structure (30) of the frame (1).
