VASCULAR REMODELING DEVICE
First Claim
1. A method of treating an aneurysm at 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 catheter proximate to the junction of the bifurcation, the catheter at least partially containing a device in a compressed state, the 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 configured to act as a scaffolding to inhibit herniation of objects out of a neck of a bifurcation aneurysm;
expanding the distal section from the compressed state to a radially expanded state at the junction of the bifurcation, wherein a distal end of the distal section moves radially outwardly and proximally relative to the proximal section, and a proximal end of the distal section moves radially inwardly and distally relative to the proximal section.

Abstract
Described herein are vascular remodeling devices that include 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 anchors the device in an afferent vessel of a bifurcation. The distal section expands from the compressed delivery state to an expanded state that may be substantially planar, approximately semi-spherical, umbrella shaped, or reverse umbrella shaped. The distal section is positioned in a bifurcation junction across the neck of an aneurysm or within an aneurysm. The intermediate section allows perfusion to efferent vessels. Before or after the device is in position, embolic material may be used to treat the aneurysm. The distal section can act as a scaffolding to prevent herniation of the embolic material. The device can be used for clot retrieval with integral distal embolic protection.

28. A method of treating an aneurysm at a junction of a bifurcation having an afferent vessel and efferent vessels, the method comprising:
-
advancing a catheter proximate to the junction of the bifurcation, the catheter at least partially containing a device in a compressed state, the device comprising; a proximal section configured to anchor in an afferent vessel; an intermediate section comprising a plurality of struts configured to allow perfusion to efferent vessels; and a distal section configured to act as a scaffolding to inhibit herniation of objects out of a neck of a bifurcation aneurysm; wherein each of the plurality of struts comprises a distal portion coupled, at a joint, to the distal section at a region of the distal section between a proximal end of the distal section and a distal end of the distal section; expanding the distal section from the catheter at the junction of the bifurcation, wherein each of the proximal end and the distal end pivots about the joint, such that the distal section at least partially everts. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)
