Abstract

An intravascular prosthetic graft is provided which includes a flexible tubular body having a first end defining at least one opening and a second end defining at least one opening. The flexible tubular body may be elongated and define a longitudinal axis. A first ring member is connected to the first end adjacent to the at least one opening of the first end. A second ring member is connected to the second end adjacent to the at least one opening of the second end. The flexible tubular body can be fabricated from a flexible material, such as, for example, DACRON.RTM., TEFLON.RTM., or other suitable material. The first and second ring members may be fabricated from a rigid material, such as metals or polymerics. A method of repairing at least a portion of an arterial system, such as, for example, treatment of an aortic aneurysm is disclosed. The method includes the steps of providing an intravascular prosthetic graft; determining a placement position for the intravascular prosthetic graft at an aneurysm site of the arterial system; introducing the intravascular prosthetic graft to the arterial system; delivering the intravascular prosthetic graft to the aneurysm site; positioning the intravascular prosthetic graft for repairing a diseased portion of an aorta at the placement position; expanding the intravascular prosthetic graft to substantially conform to an inner surface of the aorta; and fixing the intravascular prosthetic graft at the placement position. The step of fixing may include tying a suture about the exterior of the aorta. The method may further include the step of suturing the aorta to the intravascular prosthetic graft from exterior to the aorta.
