Embodiment Construction

[0020] Figures 1 to 12G Examples of bifurcation-branch devices are disclosed, as well as stent-graft systems incorporating the devices and example methods for deploying the devices and the systems. The devices, systems and methods can be used to treat endovascular diseases, such as aneurysms. Devices, systems and methods are described herein with respect to the treatment of iliac artery disease, however, those of ordinary skill in the art will understand that these devices, systems and methods may be used in other areas of the vasculature and / or other pathologies, such as the aorta - Iliac artery occlusive disease.

[0021] figure 1 and 2 Examples of furcation branch devices 100, 100A are shown respectively. The furcation-branch device 100 , 100A may generally comprise a graft material 102 and one or more scaffolds 104 attached to the graft material 102 . In the illustrated embodiment, the stent 104 may comprise a plurality of spaced apart individual stent rings that ar...

Abstract

The techniques of this disclosure generally relate to a stent-graft system including a bifurcated stent-graft, a first bifurcating branch device, and a first branch extension. The bifurcated stent-graft includes a body, a first branch limb, and a second branch limb. The first bifurcating branch device includes a body segment coupled to the first branch limb of the bifurcated stent-graft, a first branch limb, and a second branch limb. The first branch extension is within the first branch limb of the first bifurcating branch device and within an external iliac artery. The first bifurcating branch device has a wide patient applicability since the treatment can be extended proximal to the anatomical iliac bifurcation and is not limited by the common iliac artery length. The stent-graft system is suitable to treat a wide range of internal and external iliac artery diameters.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application No. 62 / 855,163, filed May 31, 2019, by Keith Perkins et al., entitled "BIFURCATING BRANCH MODULAR ILIAC BRANCH DEVICE," which states The US Provisional Application is hereby incorporated by reference in its entirety. technical field [0003] The present technology generally relates to intravascular devices, such as those used to treat diseased aortas. Background technique [0004] Conventional stent-grafts typically comprise a radially expandable reinforcing structure, eg, formed of a plurality of annular stent rings, and a cylindrical layer of graft material defining a lumen to which the stent rings are coupled. Endovascular aneurysm exclusion is the use of a stent-graft to exclude pressurized fluid flow from within the aneurysm, thereby reducing the risk of aneurysm rupture and the associated invasive surgical intervention. People with certain typ...
