1. A catheter comprising:
a catheter body;
a first guide tube having a first lumen and a second guide tube having a second lumen, the first guide tube and the second guide tube moveable between retracted positions within the catheter body and deployed positions inclined laterally away from the catheter body;
a first penetrator and a second penetrator configured to penetrate a wall of a target vessel, the first penetrator located coaxially inside of the first lumen of the first guide tube, and the second penetrator located coaxially inside of the second lumen of the second guide tube, wherein the first penetrator and the second penetrator are guided by the first guide tube and the second guide tube along different trajectories formed by the first lumen and the second lumen, respectively; and
a proximal handle comprising a movement mechanism configured to allow relative movement of the first guide tube and the second guide tube with respect to the catheter body by advancing the movement mechanism longitudinally along the catheter body between a first marker indicia line and a second marker indicia line, the movement mechanism further configured to allow relative movement of the first penetrator and the second penetrator relative to the first guide tube and the second guide tube, respectively, by advancing the movement mechanism longitudinally along the catheter body between the second marker indicia line and a third marker indicia line.
