1. A catheter comprising:
a catheter body;
a first needle and a second needle, the first needle and the second needle movable between a retracted position within the catheter body and an extended position for piercing a vessel wall;
a first guiding element and a second guiding element, the first needle coaxial with the first guiding element and the second needle coaxial with the second guiding element, the first guiding element and the second guiding element configured to be advanced outwardly from the catheter body toward the vessel wall,
the first needle configured to be advanced through the first guiding element and into the vessel wall and the second needle configured to be advanced through the second guiding element and into the vessel wall, wherein the first guiding element and the second guiding element are configured to maintain their position against the vessel wall as the first needle and the second needle are advanced into the vessel wall; and
a wire reducing the internal volume of the catheter.
