1. A guide device deployable through a vessel comprising:
- an expandable member movable between a collapsed position and an outwardly extending, expanded position; and
a guide tube operatively coupled to the expandable member and having a distal tip which is moveable between a first position generally parallel with the expandable member in the collapsed position and a second position askew to the first position,a first elongate member comprising a first lumen; and
a second elongate member comprising a second lumen and a side opening,wherein the guide tube is disposed along the second lumen and the second elongate member is disposed along the first lumen,wherein the expandable member extends between a first end connected to the first elongate member and an opposite second end connected to the second elongate member, such that the expandable member is radially displaceable in response to longitudinal displacement of the second elongate member relative to the first elongate member, andwherein the guide tube actuates between the first and second positions in response to contraction and expansion of the expandable member between the collapsed and expanded positions, respectively.

Abstract
The present disclosure provides methods and apparatuses for guiding an endovascular tool, such as a puncturing tool or an angioscope, in a radial direction, such as toward or through the sidewall of a vessel, stent, or stent graft, using elongate members and specialized catheters. The present disclosure provides methods and apparatuses for locating branch vessels from within a grafted main vessel while maintaining continuous blood flow to the branch vessel. Another aspect of the present disclosure involves a reverse cannulation system, particularly useful for stenting the abdominal aorta proximate the renal arteries and stenting the renal artery.
