1. A method for accessing a lumen of a vessel, the lumen defined by a vessel wall, the method comprising:
- a. advancing a first elongate member across the vessel wall to a deployed configuration wherein at least a portion of the first elongate member occupies the lumen, the first elongate member creating a first pathway through the vessel wall;
b. using the deployed configuration of the first elongate member to mechanically enforce an introduction angle for advancing a second elongate member across at least a portion of the vessel wall;
c. advancing the second elongate member across the vessel wall to a position wherein a second pathway is created through the vessel wall to the lumen; and
d. delivering a filler into the second pathway, wherein the filler comprises a solid setting liquid.
