1. An intraluminal device comprising:
- a proximal section configured to anchor in an afferent vessel;
an intermediate section configured to allow perfusion to efferent vessels; and
a distal section comprising an embolization coil coupled to and extending distally from the intermediate section and configured to be positioned within an aneurism.

Abstract
A vascular remodeling device is provided that can comprise a proximal section, an intermediate section, and a distal section. During deployment, the proximal section can expand from a compressed delivery state to an expanded state and anchor the device in the afferent vessel of a bifurcation. The distal section can comprise at least one embolization coil that can be positioned within an aneurysm to treat the aneurysm and expand from the compressed delivery state to an expanded state upon deployment. The intermediate section can allow perfusion to efferent vessels. Before, during, and/or after the device is positioned, additional embolic material can be used to treat the aneurysm.

8. A method of treating an aneurysm near a junction of a bifurcation having an afferent vessel and efferent vessels, the aneurysm having a neck and a fundus, the method comprising:
-
advancing a first catheter proximate to the junction of the bifurcation, the catheter at least partially containing a device in a compressed state, the device including; a proximal section configured to anchor in an afferent vessel; an intermediate section configured to allow perfusion to efferent vessels; and a distal section comprising an embolization coil coupled to and extending distally from the intermediate section and configured to be positioned within an aneurism; deploying the device from at least partially inside the first catheter to outside the first catheter at the junction of the bifurcation, wherein, during deployment, the distal section self-expands within the fundus of the aneurysm; the intermediate section self-expands and allows perfusion to the efferent vessels; and the proximal section self-expands to anchor in an expanded state to the walls of the afferent vessel. - View Dependent Claims (9, 10, 11, 12, 13)

14. A system for treating aneurysms comprising:
-
at least first and second intraluminal devices, each of the first and second devices comprising; a proximal section configured to anchor in an afferent vessel; an intermediate section configured to allow perfusion to efferent vessels; and a distal section comprising an embolization coil coupled to and extending distally from the intermediate section and configured to be positioned within an aneurism; wherein the distal section of the first device comprises at least one property that is different from a corresponding property of the second device. - View Dependent Claims (15, 16, 17, 18, 19, 20)
