A prosthetic graft in the form of a flexible tube with rigid end portions, wherein the rigid end portions each have an annular groove. The graft is used by slitting the portion of an artery containing an aneurysm or other damage to form an opening, inserting the graft through the opening into the artery, positioning the graft longitudinally within the artery, and circumferentially ligating the artery against the grooves in the rigid end portions of the graft. |
