Abstract

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.

Claims

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.
