1. An apparatus for bypassing an occlusion in a blood vessel comprising:

  • a handle;

    an outer shaft component having a side port proximal to a distal end thereof, the outer shaft component including a needle lumen there-through that includes a curved distal portion that bends from a longitudinal axis of the apparatus and terminates at the side port of the outer shaft component, wherein a proximal end of the outer shaft component is fixed within the handle at a first attachment point;

    a stabilization tube having an elongated body extending between a proximal end and a distal end thereof, the elongated body being disposed within the needle lumen of the outer shaft component, wherein the proximal end of the stabilization tube is fixed within the handle at a second attachment point that is spaced apart from the first attachment point and the elongated body and distal end of the stabilization tube are not attached to the outer shaft component; and

    a needle component configured to be slidably disposed within the stabilization tube and removable therefrom, wherein the stabilization tube minimizes resistive forces exerted onto the needle component by the outer shaft component.
