The invention relates to a medical implant (1) for the occlusion of a patients auricula sinistra by endovascular means, said implant having a cage structure (10) comprising a plurality of webs (3) that are proximally attached to a retaining ring (4) via connecting webs (2) and distally limited by a rim of converging webs (3), wherein said implant (1) consists of a self-expanding material, has in contracted state the shape of a slotted tube and, after expansion, assumes the cage structure (10) of a diameter larger than that of the retaining ring (4) and wherein at least one or several anchor elements (7) are arranged within or distally to the cage structure (10) said anchor elements being proximally connected directly or indirectly with the retaining ring (4), therein (a) the one or more anchor elements (7a) are provided at the distal end with a tip (8) with barb (9), with tip (8) and barb (9) projecting beyond the cage structure (10) with the intention for the tip (8) and barb (9) to be anchored in the muscle tissue of the auricula sinistra, or (b) the one or more anchor elements (7b) project laterally beyond the cage structure (10), extend in proximal direction in a curved configuration with the intention to be laterally supported against the muscle tissue of the auricula sinistra, or (c) a combination of alternatives (a) and (b) is provided.
