| abstract |
The invention relates to an implant (1) for blood vessels, in particular for influencing the blood flow in the area of arteriovenous defects, with a wall made up of individual filaments (2), which are brought together to form a substantially tubular mesh that extends in an axial direction from a proximal end to a distal end, wherein the individual filaments (2) cross one another and form intersections (3) with one another, wherein the implant (1) is deformable in such a way that, in an insertion catheter, it adopts a shape with a reduced diameter and, at the site of implantation, expands to adapt to the diameter of the blood vessel, wherein the filament ends are in each case brought together at least in pairs at the proximal and/or distal end of the mesh and are permanently interconnected, wherein the interconnected filament ends are shaped to be atraumatic, and wherein the filaments (2) crossing one another at the intersections (3) lying distally from the filament ends are connected directly or indirectly to one another at the proximal end (10) of the implant (1). This ensures that the implant (1), after release, also expands at the proximal end as far as the vessel walls, and the filament ends do not protrude into the vessel lumen. |
