STENT GRAFT WITH FLANGED CONTRALATERAL GATE FOR ENDOVASCULAR ANEURYSM REPAIR
A stent graft is disclosed. The stent graft includes a body portion having a sidewall and an opening at the top. The top of the sidewall is configured and arranged to engage a wall of an aorta above an aneurysmal site of a patient. An ipsilateral limb descends from the body portion. The ipsilateral limb is configured and arranged to descend into one of an iliac arteries. The stent graft further includes a contralateral gate that has a flared opening. The contralateral gate is configured and arranged to align with the other of the iliac arteries.
1 . A stent graft, comprising:
a body portion with a sidewall and an opening at the top; the top of the sidewall configured and arranged to engage a wall of an aorta above an aneurysmal site;
an ipsilateral limb descending form the body portion, the ipsilateral limb configured and arranged to align with one of an iliac arteries; and
a contralateral gate having a flared opening configured and arranged to align with the other of the iliac arteries.
2 . The stent graft of claim 1 , wherein the flare forms a complete funnel.
3 . The stent graft of claim 1 , wherein the flare forms a partial funnel.
4 . The stent graft of claim 1 , wherein the contralateral gate flares medially.
5 . The stent graft of claim 1 , wherein the contralateral gate flares anteriorly.
6 . The stent graft of claim 1 , wherein the contralateral gate flares posteriorly.
7 . The stent graft of claim 1 , wherein the contralateral gate flares laterally.
8 . The stent graft of claim 1 , wherein the ipsilateral limb descends into one of the iliac arteries.
9 . The stent graft of claim 1 , further comprising a contralateral limb configured and arranged to deploy inside the contralateral gate.
10 . The stent graft of claim 9 , wherein the contralateral limb descends into the other of the iliac arteries.
11 . A method of deploying a stent graft at an aneurysmal site of an abdominal aortic artery of a patient, comprising the steps of
deploying a stent graft at an aneurysmal site of an abdominal aortic artery of a patient, the stent graft having a body portion with a sidewall and an opening at the top, an ipsilateral limb descending form the body portion, and a contralateral gate having a flared opening;
positioning the top of the sidewall against a wall of the abdominal aorta above the aneurysmal site;
positioning the ipsilateral limb into one of an iliac arteries, and
positioning the contralateral gate in alignment with the other of the iliac arteries.
12 . The method of claim 11 , further comprising the step of manipulating a wire through the flared opening of the contralateral gate.
13 . The method of claim 11 , further comprising the step of manipulating a contralateral limb inside the contralateral gate.
14 . The method of claim 13 , further comprising the step of deploying a contralateral limb inside the contralateral gate.
