  • Patent number: 8870946
    Abstract: A bifurcated intravascular stent graft comprises primary stent segments and a primary graft sleeve, forming a main fluid channel and having a side opening therethrough. An external graft channel formed on the primary graft sleeve has a first end communicating with the side opening and an open second end outside the primary graft sleeve, thereby providing a branch flow channel from the main channel out through the side opening and external graft channel. The primary stent segments and graft sleeve engage an endoluminal surface of a main vessel and form substantially fluid-tight seals. The stent graft further comprises a secondary stent graft, which may be positioned partially within the external graft channel, through the open second end thereof, and partially within a branch vessel. The secondary stent graft engages the inner surface of the external graft channel and the endoluminal surface of the branch vessel, thereby forming substantially fluid-tight seals.

  • Patent number: 8211121
    Abstract: A method for occluding an anatomical structure (such as a vessel or duct) having a lumen comprises: introducing percutaneously into the body of the patient a delivery device; advancing the delivery device through an extraluminal space within the patient's body to an occlusion site outside the lumen of an anatomical structure; deploying a pair of longitudinally-extending clamping jaws from the delivery device; and occluding the anatomical structure with the clamping jaws. The advance of the delivery device and the deployment of the clamping jaws is guided by near-real-time imaging of a target region of a body of a patient, the target region including the occlusion site on the anatomical structure. The delivery device is guided to the occlusion site outside the lumen of the anatomical structure, and the structure is occluded with the deployed clamping jaws engaging the exterior of the structure.

  • Patent number: 7766962
    Abstract: A stent anastomosis comprises a stent segment reconfigurable between a deployment configuration and a shortened, transversely expanded deployed configuration having a transverse dimension larger than its longitudinal dimension. In the deployed configuration, the stent segment engages an inner surface of an intravascular graft, securing the end of the graft within a vessel and forming a seal between the graft and an endoluminal surface of the vessel. The stent segment includes at least one securing member that extends outward from the stent segment in the deployed configuration, that pierces and penetrates the graft, and that pierces the endoluminal surface of the vessel to secure the graft within the vessel. In the deployed configuration, the stent segment can compress the graft against the endoluminal surface of the vessel to form the seal.

  • Patent number: 7220274
    Abstract: A stent graft comprises two stent segments connected to open ends of a graft, arranged along the length thereof without overlap, reducing the transverse size and facilitating deployment. It may include longitudinal struts, sliding stent, additional stent segments, removable stent(s), etc. Various methods are employed for deployment. Other stent graft deploying methods comprise independently introducing and maneuvering graft and stent segments to the repair site from one or more introduction sites, and assembling the stent graft at the repair site. Intravascular and/or extravascular deployment hardware may be employed. Additional sealing and/or structural stent segments may be deployed. Branched grafts may be deployed. Removable stent segment(s) may be employed for positioning the graft and then later removed. A stent anastomosis for securing/sealing a graft end is disclosed. A branched stent graft including two branch stent grafts deployed side-by-die within a main stent graft is disclosed.

  • Patent number: 6645242
    Abstract: A bifurcated intravascular stent graft comprises primary stent segments and a primary graft sleeve, forming a main fluid channel and having a side opening therethrough. An internal graft channel formed within the primary graft sleeve has an inner open end within the primary graft sleeve and an open outer end communicating with the side opening, thereby providing a branch flow channel from the main channel out through the side opening. The primary stent segments and graft sleeve engage an endoluminal surface of a main vessel and form substantially fluid-tight seals. The stent graft further comprises a secondary stent graft, which may be positioned partially within the internal graft channel, through the side opening, and partially within a branch vessel. The secondary stent graft engages then inner surface of the internal graft channel and the endoluminal surface of the branch vessel, thereby forming substantially fluid-tight seals.

  • Patent number: 6319278
    Abstract: A low profile stent graft for treatment of vascular abnormalities such as aneurysms. The endoskeleton of the stent graft has first and second self-expandable stents. The stents are spaced apart and connected together by at least one, and preferably three, flexible strut members. A tubular graft is placed around the endoskeleton while the stents are in a partially compressed state, and attached to the stents. A bifurcated configuration is disclosed that can be employed where the stent graft is to be used for repair of an aneurysm of the abdominal aorta.
