Abstract:
1. A combination comprising an insertion catheter, an implant, a guide wire and a retaining element, wherein the implant is attached to the guide wire via the retaining element, the implant for blood vessels for influencing blood flow in areas of arteriovenous malformations, said implant having a wall comprising individual filaments combined so as to form a circular braiding, wherein the filaments have ends and said circular braiding being positionable in elongated form and with a reduced diameter in the insertion catheter and expandable at a placement site thus adapting to a vessel diameter and increasing its braiding density, wherein the circular braiding has a proximal end and a distal end, and at the proximal end the filament ends are joined at least in pairs and connected with each other permanently, with the joined filament ends being formed such that they do not cause traumatic effects and forming connecting elements that attach to the retaining element, the retaining element being provided over its periphery with recesses into which the connecting elements are fitted, the combination further comprising a hose drawn over the retaining element in a closed-form way with the connecting elements fitted therein so that the implant is liberated by retraction of the hose, wherein the drawn-over hose is not extendable over the circular braiding, and wherein the circular braiding has a surface coverage in stress-free arrangement achieved by the individual filaments in the range of between 30 and 80%, and the retaining element is secured to the guide wire, the retaining element being retractable into the insertion catheter by retracting the guide wire into the insertion catheter after liberation of the implant.
