Implant for influencing the blood flow in arteriovenous defects
First Claim
1. An implant for blood vessels to influence the flow of blood in an implantation site comprising the area of arteriovenous malformations, said implant having proximal and distal ends and a wall comprising individual filaments forming a tubular braiding extending in axial direction from the proximal to the distal end, whereinthe individual filaments have ends at the proximal and/or distal end of the braiding and cross one another to form points of intersection, and whereinthe implant is 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 and adapt to the diameter of the blood vessel into which it is inserted, and whereinthe 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, andwith the filament ends connected with each other being shaped so as to be atraumatic, characterized in thatthe filaments crossing one another at the points of intersection located distally from the proximal ends are connected with each other at said points of intersection in the area of the proximal end of the implant, in the following manner:
- the intersected filaments in the area of the proximal end of the implant are passed through loops formed by wires secured at the proximal end of the implant, the wires originating from the points where the filaments are brought together at the proximal end of the implant, the starting point and the end point of the wires being at the proximal end of the implant, the individual wires extending from the proximal point of attachment in distal direction and passed around the proximal points of intersection of the filaments.

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.
