Implant for the influence of blood flow in arteriovenous malformations

摘要

Implant for blood vessels, in particular to act on blood flow in the area of arteriovenous malformations, with a wall of individual filaments (2), which are grouped together to give a network essentially in the form of tubes, which extends in axial direction from the proximal end towards the distal end, in which the individual filaments (2) intersect each other and form intersecting points (3), the implant (1) can be shaped so that in an introduction catheter it adopts a shape with reduced diameter and expands at the implant site adapting to the diameter of the blood vessel, and at the proximal and / or distal end of the network the filament ends meet respectively at least in pairs and join together permanently , forming the ends of filaments joined together in an atraumatic manner and the filaments (2) that intersect at the intersection points (3) that are d aretal to the ends of filaments are connected to each other at the proximal end (10) of the implant (1) respectively directly or indirectly, characterized in that the filaments (2) at the intersection points (3) that are at the end The proximal (10) of the implant (1) are guided through loops (8) that are formed by threads (9) fixed in the implant (1).
