HINGED ENDOVASCULAR DEVICE
A hinged endovascular device including a first stent portion having a first proximal end and a first distal end and a second stent portion having a second proximal end and a second distal end. A hinge assembly couples the first distal end and the second proximal end to each other. A method of inserting the device into a body lumen is also disclosed.
1 . A hinged stent comprising:
a first stent portion having a first proximal end and a first distal end;
a second stent portion having a second proximal end and a second distal end; and
a hinge assembly coupling the first distal end and the second proximal end to each other.
2 . The hinged stent according to claim 1 , further comprising a first graft coupled to the first stent portion.
3 . The hinged stent according to claim 1 , further comprising a second graft coupled to the second stent portion.
4 . The hinged stent according to claim 1 , wherein the hinge assembly comprises first and second hinges diametrically opposed from each other.
5 . A method of inserting a hinged prosthesis into a body lumen having a main lumen with first and second lumens extending therefrom at a bifurcation, the method comprising the steps of:
(a) inserting a prosthesis having a first portion, a second portion, and a hinged portion coupling the first portion to the second portion into the first lumen distally of the bifurcation;
(b) advancing the first portion of the prosthesis toward the bifurcation;
(c) pivoting the first portion of the prosthesis into the second lumen at the bifurcation;
(d) advancing the first portion into the second lumen while advancing the hinged portion toward the bifurcation; and
(e) advancing the hinged portion in a proximal direction away from the bifurcation.
6 . The method according to claim 5 , wherein step (e) comprises advancing the hinged portion to a location in the main lumen proximal of the aneurysm.
7 . A hinged stent graft assembly comprising:
a first stent portion having a first proximal end and a first distal end;
a first graft portion at least partially covering the first stent portion;
a second stent portion having a second proximal end and a second distal end;
a second graft portion at least partially covering the second stent portion; and
a hinge coupling the first graft portion and the second graft portion to each other.
