The invention relates to an implant to be used for the occlusion of aneurysms in the region of vessel branches, in particular bifurcation aneurysms (A), with a mesh structure (3, 4), said implant comprising—from proximal to distal—a fixing section (b) by means of which the implant can be supported on the wall of a vessel, a permeable section (c) for the region of the vessel bifurcation, and a distal section (d) in which the implant is radially expanded in comparison to section (b) and which is intended for placement into the aneurysm (A). In the area of sections (c) or (d) a separation zone (T1, T2) is arranged that closes off at least partially the neck of the aneurysm, the distal section (d) being provided with a plurality of filaments and/or loops (12) connecting to section (c) and said filaments/loops (12) forming an angle of between −45° and +175° in relation to the longitudinal axis of the implant (1), wherein a positive angle is indicative of filaments pointing radially outward and a negative angle of filaments/loops (12) pointing radially inward. Alternatively, the distal section (d) may also be enlarged in the form similar to a sphere, mushroom, anchor or ellipsoid.
