Abstract
Bifurcated endovascular prostheses used to treat diseased blood vessels, such as arteries, are disclosed. In some embodiments, the bifurcated endovascular prosthesis is configured to be implanted within the diseased blood vessels adjacent a diseased section. The bifurcated endovascular prosthesis includes a primary stent graft and a secondary stent graft. The primary stent graft includes a pocket or sleeve disposed within a bore. A proximal portion of the secondary stent graft is disposed within the pocket or sleeve. Blood flow through the bifurcated endovascular prosthesis is divided into two flows, a first flow through the primary stent graft and a second flow through the secondary stent graft.
Claims19
A method of manufacturing a bifurcated endovascular prosthesis, comprising:
- constructing a primary stent graft construct, comprising:
- obtaining a pocket mandrel and a first body mandrel;

- covering the covered pocket mandrel and the first body mandrel with a second polymeric covering;
- and
- constructing a secondary stent graft construct, comprising:
- obtaining a second body mandrel;
- and
- covering the second body mandrel with a third polymeric covering.
