FENESTRATION DEVICES, SYSTEMS, AND METHODS
First Claim
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 movable between a first position generally parallel with the expandable member in the collapsed position and a second position askew to the first position.

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.

18. A method for guiding an endovascular tool in a vessel comprising:
-
deploying a guide device into a main vessel wherein the guide device comprises; 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 movable between a first position generally parallel with the expandable member in the collapsed position and a second position generally orthogonal to the first position. outwardly extending the expandable member and thereby causing movement of the guide tube to the second position with only minor disruption of fluid flow through the vessel. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26)
