An aneurysm embolization device (12) which may be used to occlude a blood vessel or aneurysm. The device has a plurality of support struts (24a-d) which form a substantially ellipsoidal shape. The support struts are preferably formed from a nickel-titanium alloy, such as nitinol, which has superelastic characteristics. A mesh sleeve (26) is disposed over the support struts. The mesh sleeve is preferably formed of a thrombogenic material, such as polyurethane, so as to encourage the formation of blood clots and scar tissue to permanently occlude the vessel. <IMAGE> |
