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. At least one self-expanding device associated with the graft, the self-expanding device operating to attach the graft within vasculature.
Claims20
A device having a bifurcation for repairing an aortic aneurysm close to or involving the aortic bifurcation comprising the aorta having an arterial wall and the first and second iliac arteries extending therefrom in a patient, the device comprising:
- a main body;
- first and second legs joined to said main body at the bifurcation, and main body and said first and second legs being formed of a flexible surgically implantable material, said main body and said first and second legs having respectively first, second and third openings therein in communication with each other;
- a first self-expanding sealing device associated with said main body adjacent the first opening;
- and
- a second self-expanding sealing device associated with said first leg adjacent the second opening;
- wherein said device is capable of intraluminal implantation by a catheter into the aortic bifurcation through said first iliac artery such that said main body can be sealed by said first sealing device in said aorta, said first leg can be sealed by said second sealing device in said first iliac artery, and said second leg can be deployed.
An endovascular kit for repairing an aortic aneurysm close to or involving the aortic bifurcation, said kit comprising:
- a graft having a main body and having first and second legs joined to the main body in a bifurcation;
- wherein the main body and the first and second legs are formed of a flexible surgically implantable material;
- wherein the main body and the first and second legs have respectively first, second and third openings therein in communication with each other;
- a self-expanding sealing device secured to the main body adjacent the first opening and an additional self-expanding sealing device secured to the first leg adjacent the second opening;
- and
- a pull line removably connected to the second leg.
An endovascular graft suitable for permanent implantation in the vasculature of a patient for repairing an aneurysm proximate a bifurcation, the endovascular graft comprising:
- (a) a support device, said support device having a main member and first and second leg members in fluid communication with the vasculature;
- (b) a self-expanding device, said self-expanding device operating to attach the main tubular member and at least one of the first and second tubular leg members to the vasculature;
- and
- (c) a radiopaque marker attached to said support device.
The endovascular graft for attachment in a patient's vasculature for repairing an aneurysm proximate to a bifurcation, the endovascular graft comprising:
- (a) a main body having a proximal end;
- (b) first and second members each having distal ends and each joined to and in fluid communication with said main body;
- (c) a first self-expanding sealing device attached to said main body at its proximal end;
- (d) a second self-expanding sealing device attached to at least one of said first and second members at their respective distal ends, said first and second sealing devices configured to provide a substantially fluid-tight seal between the vasculature and the endovascular graft so that there is fluid communication between the vasculature and said main body and said first and second members, wherein the endovascular graft is intraluminally deployed into the vasculature using a catheter.
An endovascular graft for permanent implantation in a patient's vasculature for repairing the vasculature proximate to a bifurcation in the vasculature, the bifurcation forming a first artery and a second artery, the endovascular graft comprising:
- (a) a main body having a proximal end and extending proximally into the bifurcation in a vasculature of a patient;
- (b) first and second members each having distal ends and each joined to and in fluid communication with said main body, said first member configured to extend distally into the first artery and said second member configured to extend distally into the second artery;
- (c) a first self-expanding sealing device attached to said main body at its proximal end;
- and
- (d) a second self-expanding sealing device attached to each of said first and second members at their respective distal ends, said first and second sealing devices configured to provide a substantially fluid-tight seal between the vasculature and the endovascular graft so that there is fluid communication between the vasculature and said main tubular body and said first and second tubular members, wherein the endovascular graft is intraluminally deployed into the vasculature using a catheter.
A graft for attachment in a patient's vasculature having an inside diameter, the graft configured for repairing an aneurysm proximate to a bifurcation, the graft comprising:
- (a) a main tubular body having a proximal end and a distal end;
- (b) first and second tubular members each having proximal and distal ends, said first and second tubular members each being joined at its proximal end to and being in fluid communication with said distal end of said main tubular body;
- (c) a first self-expanding anchor device attached to said main tubular body at its proximal end;
- and
- (d) a second self-expanding anchor device attached to said first tubular member at its distal end, wherein each of said first and second anchor devices comprises a self-expanding spring structure having a plurality of protrusions for engaging the patient's vasculature, said substantially the same as or larger than the inside diameter of the vasculature, wherein the graft is intraluminally deployed into the vasculature using a catheter.
