The invention relates to an implant (1) for blood vessels, in particular to influence the flow of blood in the area of arteriovenous malformations, said implant having a wall consisting of individual filaments (2) forming, in essence, a tubular braiding extending in axial direction from the proximal to the distal end, wherein the individual filaments (2) cross one another and form points of intersection (3), and wherein the implant (1) being deformable in such a manner that, when accommodated in an insertion catheter, it is shaped so that its diameter is reduced and can be expanded at the implantation site adapting to the diameter of the blood vessel, and wherein the filament ends at the proximal and/or distal end of the braiding are each brought together at least in pairs and connected with each other permanently, and with the filament ends connected with each other being shaped so as to be atraumatic, and wherein the filaments (2) crossing one another at the points of intersection (3) located distally from the filament ends are directly or indirectly connected with each other at the proximal end (10) of the implant (1). It is ensured in this manner that the implant (1) when released expands up to vessel walls also at the proximal end and the filament ends do not protrude into the vessel lumen. |
