  • Publication number: 20070203565
    Abstract: The invention provides a method of providing an endovascular bypass. The method includes the steps of inserting an elastic needle carrying a guidewire adjacent an ostium via a catheter and extending the needle through a branch vessel wall. The method continues by extending the needle through the extravascular space and inserting the needle through a main vessel wall to create an opening. The needle is retracted, leaving the guidewire in place. A bypass stent graft is inserted along the guidewire to provide a pathway between the branch vessel and the main vessel, and the inserted bypass stent graft is expanded. The branch vessel is occluded between the ostium of the bypass stent graft and the main vessel, and a main stent graft is inserted in the main vessel proximate the opening in the main vessel wall.

  • Publication number: 20070055350
    Abstract: Modular branch vessel stent-graft assemblies for the treatment arterial or vascular disease at the branch of two or more arteries or blood flow passageways, including, for example, abdominal aortic aneurysms are assembled in a patient's trunk/parent artery, from at least two components; a first component and a second component. The first and second components each include a first and second window, or fenestration. The second component couples with the first component by fitting at least partially in the first component to form the modular branch vessel stent-graft assembly with two selectively locatable branch openings. As the first and second components are deployed, the second component is selectively position able relative to first component so that the first and second component first and second windows overlap to form two branch openings whose longitudinal and angular positions are selectable within a range.
