1. An intraluminal device comprising:
- a proximal section configured to be positioned and anchored in a blood vessel, the proximal section having a central longitudinal axis;
a distal section having (i) a first wing including first base struts, the first base struts extending from a first side of the distal section and (ii) a second wing including second base struts, the second base struts extending from a second side of the distal section, substantially diametrically opposing the first side, the first base struts being connected to each other by a first end strut of the first wing, the second base struts being connected to each other by a second end strut of the second wing, the first and second wings being configured to expand from a collapsed state to an expanded state;
at least two junctures between the proximal section and the distal section, the first wing and the second wing being fixedly connected to each other only at the at least two junctures, wherein each of the first base struts extends from a different one of the at least two junctures and each of the second base struts extends from a different one of the at least two junctures, each of the first base struts being between the first end strut and a corresponding one of the at least two junctures, each of the second base struts being between the second end strut and a corresponding one of the at least two junctures;
wherein, when the second wing expands to the expanded state, the second wing is configured to extend transverse to the axis from the second side to the first side through an opening in the first wing, such that the first end strut is on the second side and the second end strut is on the first side.

Abstract
An intraluminal device may be used at a bifurcation to anchor in an afferent vessel, allow perfusion to efferent vessels, and act as scaffolding to inhibit herniation of objects out of a neck of a bifurcation aneurysm. An intraluminal device may include a first side; a second side opposite the first side across a longitudinal axis of the intraluminal device; a proximal section configured to anchor in an afferent vessel; a distal section comprising a first wing and a second wing wherein, in an expanded state, the first wing extends from the first side to the second side and the second wing extends from the second side, through an opening of the first wing, and to the first side.

17. A method of preparing an intraluminal device, comprising:
-
providing the intraluminal device comprising a proximal section and a distal section, the distal section having (i) a first wing having first base struts, the first base struts extending from a first side of the distal section, the first base struts being connected to each other by a first end strut of the first wing and (ii) a second wing having second base struts, the second base struts extending from a second side of the distal section, substantially diametrically opposing the first side, the second base struts being connected to each other by a second end strut of the second wing; bending the first wing to extend from the first base struts on the first side to the first end strut on the second side; and bending the second wing to extend from the second base struts on the second side to the second end strut on the first side through an opening in the first wing while the first wing and the second wing are fixedly connected to each other only at at least one-two junctures between the proximal section and the distal section, wherein each of the first base struts extends from a different one of the at least two junctures and each of the second base struts extends from a different one of the at least two junctures, each of the first base struts being between the first end strut and a corresponding one of the at least two junctures, each of the second base struts being between the second end strut and a corresponding one of the at least two junctures. - View Dependent Claims (18, 19, 20, 21, 22)
