A device ( 1 ) for reinforcing and relieving a blood vessel ( 2 ) in a vessel dilation ( 3 ) thereof is provided. The device includes a stent ( 5 ) with metal reinforcement ( 4 ), which, in the position of use, bridges the vessel dilation ( 3 ) and can be anchored outside of the vessel dilation ( 3 ) on the blood vessel ( 2 ). The device ( 1 ) includes an insertion cannula ( 6 ), inside which the stent ( 5 ) is located during the insertion into the blood vessel ( 2 ) in a shape, in which it has a small radial extent. Once the stent ( 5 ) has left the insertion cannula ( 6 ), it automatically expands in order to correspond approximately to the vessel cross section. For anchoring the stent ( 5 ), the device is provided with pin anchors ( 7 ), which can pierce the vessel wall from inside, which are each attached to a traction element or thread ( 8 ), and which are set in a transverse arrangement after piercing through the vessel wall. The anchors ( 7 ) are connected to the stent ( 5 ) after it is positioned using the traction element ( 8 ). |
