Abstract
Graft having a bifurcation for repairing an aneurysm in the vicinity of an aortic bifurcation in a patient comprising a main tubular body and first and second tubular legs joined to said main body in a bifurcation. The main body and the legs are formed of a flexible surgically implantable material. The main body and each of the first and second legs having an opening therein in communication with the other openings. Expandable spring attachments are secured to the main body adjacent the opening in the main body. An additional expandable spring attachment is secured to one of said legs adjacent the opening in said one leg.
Claims7
A method for intraluminal emplacement of a graft in a bifurcated vessel of a patient, the method comprising:
- providing a graft having a main body, with a first self-expanding device, the graft further having a first leg portion and a second leg portion with a second self-expanding device;
- inserting the graft intraluminally into a main vessel of a patient, the main vessel having a bifurcation forming a first minor vessel and a second minor vessel;
- positioning the main body of the graft in the main vessel;
- releasing the first self-expanding device and the main body of the graft in the main vessel;
- positioning the second leg portion of the graft in the second minor vessel;
- and
- releasing the second self-expanding device and the second leg portion of the graft in a second minor vessel.
A method for emplacement of a bifurcated graft for repairing an aotic aneurysm proximate an aortic bifurcation joining first and second iliac arteries of a patient, the method comprising:
- providing a graft having a main body, a first leg portion, a second leg portion, and a self-expanding affixation system operatively associated with the main body and at least one leg portion;
- passing the graft through a first iliac artery of a patient;
- positioning the graft proximate the aortic aneurysm having a superior end;
- and
- permitting the affixation system to self-expand to thereby attach the main body of the graft proximate the superior end of the aortic aneurysm and the first leg portion in the first iliac artery.
A method for intraluminal emplacement of a graft in a bifurcated vessel of a patient, the method comprising:
- providing a graft having a main body including a first self-expanding attachment system, the graft further having a first leg portion including a second self-expanding attachment system and a second leg portion;
- inserting the graft intraluminally into a main vessel of a patient, the main vessel having a bifurcation forming a first minor vessel and a second minor vessel;
- positioning the main body of the graft in the main vessel and the first leg portion in the first minor vessel;
- securing the first self-expanding attachment system and the main tubular body of the graft in the main vessel;
- securing the second self-expanding attachment system and the first leg portion of the self-expanding graft in the first minor vessel;
- and
- positioning the second leg portion of the graft in the second minor vessel.
