An aneurysm filling system includes a guide catheter, a delivery tubing containing a plurality ol embolizing units ol an embolizing material, and a pushrod within said delivery tube. The pushrod pushes the embolizing units out of the delivery tubing once the delivery tube has been guided through the guide catheter to a delivery position. A method for treating an aneurysm includes deploying an endoluminal prosthesis and an embolizing material adjacent the aneurysm. The embolizing material is expanded to fill a portion of the aneurysm. The endoluminal prosthesis retains the expanded embolizing material within the aneurysm. A vascular implant system for treating an aneurysm includes an endoluminal prosthesis, a guide catheter including a delivery tubing slidably carried therein, and an embolizing material positioned within the delivery tubing. The embolizing material expands and fills a portion of the aneurysm when deployed from the delivery tubing. The prosthesis retains the expanded embolizing material within the aneurysm.
