摘要:
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 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 polymer 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 polymer loops forming a generally spherical shape.
