The invention relates to an implant for vascular applications that can be transported by means of a catheter and is intended in particular to influence the blood flow in the area of arteriovenous malformations, such as fistulas and aneurysms, to fill the saclike dilation of the malformation, promote thrombus formation and cover the neck of the malformation. The implant according to the invention is provided with an occlusion unit (1, 13) having a three-dimensional shape constructed from several subunits (5a, 14) from a framework of struts (5, 16, 17), with a covering, preferably a membrane (6), being located between struts (5, 16, 17).
