1. An embolization device deployment system comprising:
- a catheter having a proximal end, a distal end, and a lumen extending throughout the length of the catheter;
an embolization device comprising a plurality of arcuate support struts, said support struts being connected to each other to form a structure of a substantially ellipsoidal configuration, said embolization device further comprising a mesh sleeve disposed over and attached to said support struts, said embolization device being slidingly disposed within the lumen at the distal end of the catheter;
a hub having a lumen extending therethrough, said hub being mounted on the proximal end of the catheter and the lumen of the hub communicating with the lumen of the catheter; and
, a pusher mechanism disposed through the lumen of the hub and the lumen of the catheter, said pusher mechanism being used to displace said embolization device from within the lumen at the distal end of the catheter to thereby deploy said embolization device within a blood vessel.

Abstract
An aneurysm embolization device which may be used to occlude a blood vessel or aneurysm. The device has a plurality of support struts 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 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.

16. An embolization device deployment system comprising:
-
a catheter having a proximal end, a distal end, and a lumen extending throughout the length of the catheter;
an embolization device comprising a plurality of arcuate support struts, said support struts being comprised of a tube, said tube having a tubular wall and a lumen extending therethrough, said tube further having a proximal end, a distal end, and a plurality of longitudinal cuts through the wall of the tube, said cuts extending from a point near the proximal end of the tube and extending to a point near the distal end of the tube, said support struts being biased outwardly to form a substantially ellipsoidal structure, said embolization device further comprising a mesh sleeve disposed over and attached to said support struts, said embolization device being slidingly disposed within the lumen of the distal end of the catheter;
a hub having a lumen extending therethrough, said hub being mounted on the proximal end of the catheter and the lumen of the hub communicating with the lumen of the catheter; and
,a pusher mechanism disposed through the lumen of the hub and the lumen of the catheter, said pusher mechanism being used to displace said embolization device from within the lumen at the distal end of the catheter to thereby deploy said embolization device within a blood vessel. - View Dependent Claims (17, 18, 19, 20, 21, 22)
