VASCULAR REMODELING DEVICE
First Claim
1. A method of treating an aneurysm at a bifurcation having an afferent vessel and efferent vessels having a junction, 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 generally spherical vascular remodeling device in a compressed state;
positioning the device at the junction of the bifurcation; and
withdrawing the catheter and leaving the device at the junction of the bifurcation, wherein the device acts as a scaffolding to inhibit herniation of objects out of the neck of the aneurysm and wherein the device permits perfusion of fluid to the efferent vessels.

Abstract
A generally spherical vascular remodeling device is permanently positionable at a junction of afferent and efferent vessels of a bifurcation having an aneurysm. After positioning the device at the junction to substantially conform the device to the shape of the junction, the device acts as a scaffolding to inhibit herniation of objects out of the aneurysm and the device permits perfusion to the efferent vessels. Positioning the device may include deployment and mechanical or electrolytic release from a catheter. Embolic material may be inserted in the aneurysm before or after positioning the device. The device may have a first end, a second end substantially opposite to the first end, and a plurality of filaments extending between and coupled at the first end and the second end. Such devices may be football shaped, pumpkin shaped, or twisted. The device may include a plurality of loops forming a generally spherical shape.

14. A generally spherical remodeling device comprising:
-
a first end; a second end substantially opposite to the first end; and a plurality of filaments extending between the first end and the second end and coupled at the first end and the second end, wherein the device is configured to be positioned at a junction of a neurovascular bifurcation comprising at least one afferent vessel, efferent vessels, and an aneurysm having a neck, to act as a scaffolding to inhibit herniation of objects out of the neck of the aneurysm, and to permit perfusion of fluid to the efferent vessels. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A remodeling device comprising a plurality of loops forming a generally spherical shape, wherein the device is configured to be positioned at a junction of a neurovascular bifurcation having an aneurysm, wherein the device is configured to act as a scaffolding to inhibit matter from herniating out of the aneurysm, and wherein the device is configured to permit perfusion of blood to efferent vessels of the bifurcation.
