Embodiment Construction

[0108]Referring to FIG. 1, a system 2 for introducing an expandable device 4 into a cerebral aneurysm is shown. A first catheter 6 extends through a penetration in the femoral artery and up to the carotid artery. A second catheter 8 is advanced through the first catheter 6 and into the cerebral vasculature to the site of the aneurysm or other abnormality. A delivery catheter 10 is then advanced through the second catheter 8. The catheter 10 delivers an expandable device 4 which partially fills the aneurysm as will be described below. The system 2 also has an energy supply 12 for heating the aneurysm to shrink the aneurysm as will be described below.

[0109]After the expandable device 4 has been delivered to the aneurysm and expanded, the aneurysm is reduced in size as shown in FIG. 6. The aneurysm may be shrunk partially toward the expandable device 4, into engagement with the expandable device 4, or may even be shrunk until the expandable device 4 is also reduced in size. An advantag...

Abstract

A device for treating vascular malformations includes a primary coil and secondary windings. The primary coil provides resilience and structural integrity while the secondary windings fill interstitial spaces in the primary coil to isolate the vascular malformation. The device may have increased density along a central portion to isolate the malformation. In another aspect, the device may have a central opening through which embolic materials may be delivered.
