Abstract
Methods of accessing a destination vessel involve use of a catheter having an outer guide and an inner guide. The outer guide includes an outer guide lumen, a distal end, a proximal end, and a predetermined deflection location proximate the distal end. The inner guide includes an inner guide lumen, a pre-formed distal end, and a proximal end. An access method can involve axially displacing the inner guide beyond the distal end of the outer guide, axially rotating the inner guide relative to the outer guide, and changing a bend angle at the predetermined deflection location of the outer guide to direct the pre-formed distal end of the inner guide for finding and cannulating the destination vessel. A payload can be delivered into the destination vessel via the inner guide, or via the outer guide upon removal of the inner guide.
