Abstract

A blood vessel implant to influence the flow of blood in the area of arteriovenous malformations. The implant has a wall of individual filaments forming a tubular braiding extending axially from the proximal to the distal end, the individual filaments crossing and forming points of intersection. The implant is deformable so that 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. 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. The filament ends connect with each other and are shaped so as to be atraumatic The filaments cross at the points of intersection distally from the filament ends and are connected with each other at the proximal end of the implant.
