  • Publication number: 20080262595
    Abstract: A stent graft includes at least one aperture extending through the main body thereof, into which an extension portion may be deployed for positioning within an adjacent branch flow lumen. The extension portions include self biasing features, wherein the extension is biased into engagement with the main body to seal the interface thereof. Additionally, the extension portion may be configured for tortuous or deviated anatomy, to enable sealing of the extension portion with the body while extending the extension portion in a substantially non-radial direction from the main body.

  • Publication number: 20080228255
    Abstract: A positionable stent-graft delivery system includes a stent-graft, a tip capture mechanism radially constraining a proximal portion of an anchor stent ring of the stent-graft, and a positioning mechanism for positioning the tip capture mechanism. The positioning mechanism includes tensioner guides and cords. To position the tip capture mechanism, a cord is retracted through the respective tensioner guide, e.g., by the physician. Retraction of the cord, in turn, pulls the tip capture mechanism towards a distal end of the tensioner guide. In this manner, the stent-graft is readily repositioned.

  • Publication number: 20080228256
    Abstract: A braided flange branch graft formed of a braided super elastic memory material includes a neck between an inner flange and an outer flange. The neck is positioned in a side opening in a sidewall of a main stent graft and the inner flange and outer flange are deployed on opposite sides of the sidewall. The inner flange and the outer flange have a diameter greater than a diameter of the side opening in the sidewall of the main stent graft. Thus, the sidewall of the main stent graft is sandwiched between the inner flange and the outer flange securely and simply mounting the braided flange branch graft to the main stent graft. The braided flange has a substantially unobstructed fluid communication passage therethrough. Further, when stretched into a substantially cylindrical shape for delivery, the braided flange branch graft has a small delivery profile and is extremely flexible.

  • Publication number: 20080114443
    Abstract: A proximal anchor stent ring of an endoprosthesis includes proximal apexes, distal apexes, struts extending between the proximal apexes and the distal apexes, and anchor pins. The struts, the proximal apexes, and the distal apexes define an imaginary cylindrical surface. A pair of the anchor pins is located on the struts adjacent each of the proximal apexes, the anchor pins extending inwards from inside surfaces of the struts and protruding from the struts radially outward from the cylindrical surface. By locating the anchor pins inwards, the delivery profile of the proximal anchor stent ring is minimized.

  • Publication number: 20080114441
    Abstract: An endoluminal prosthesis including a tubular graft having a proximal end and a distal end; a suprarenal spring stent operably connected to the proximal end, the suprarenal spring stent having suprarenal positive apices and suprarenal negative apices connected in a sinusoidal ring pattern by suprarenal struts; and a sealing spring stent operably connected to the tubular graft, the sealing spring stent having sealing positive apices, sealing negative apices, and intermediate sealing negative apices connected in a ring pattern, the sealing negative apices alternating with the intermediate sealing negative apices between adjacent sealing positive apices, the sealing positive apices being connected to the sealing negative apices by sealing struts, and the sealing positive apices being connected to the intermediate sealing negative apices by intermediate sealing struts. The suprarenal positive apices are axially aligned with the intermediate sealing negative apices.

  • Publication number: 20080114442
    Abstract: A delivery system for an endoprosthesis includes a spindle having a spindle body and spindle pins extending radially outward from the spindle body. The delivery system further comprises a tip comprising a sleeve, the spindle pins extending from the spindle body toward the sleeve. The endoprosthesis includes a proximal anchor stent ring having spindle pin catches and anchor pins. The spindle pins of the spindle extend into the spindle pin catches and the sleeve radially constrains the anchor pins.

  • Publication number: 20070250152
    Abstract: A stent-graft includes a short tube graft and patch located inside of a primary graft. The patch forms a smooth and reliably sealed transition between the primary graft and the short tube graft. Accordingly, the disruption to fluid, e.g., blood, flowing through the lumen of the primary graft by the short tube graft is minimal. Further, the patch supports the inner end of the short tube graft. Thus, the patch, the short tube graft and the primary graft form a stable three-dimensional structure.

  • Publication number: 20070239252
    Abstract: A method of using a delivery system includes advancing a stent to be located within an ostium of a vessel; advancing a basket actuation button of a handle to deploy a basket of the basket assembly; moving the basket into engagement with a parent vessel, the basket having a larger diameter than a diameter of the ostium; deploying the stent within an ostial lesion of the vessel; and contracting the basket.

  • 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: 20060247760

  • Publication number: 20060184227
    Abstract: A system for treating a vascular condition and methods for assembling and using such a system. The system includes a catheter inner member, a stent framework, a graft material aligned with the stent framework to form a stent-graft assembly, and a slidable sheath. Multiple bands are spaced along the length of a distal portion of the inner member, each band at least partially encircling the inner member. The stent framework includes multiple rings. The stent-graft assembly is mounted on the inner member such that the stent framework rings are interspaced with the inner member bands. The movable sheath encloses the stent-graft assembly. As the sheath is withdrawn to deploy the stent-graft assembly, the interspaced bands and rings restrict axial movement of the assembly and prevent longitudinal compression or buckling of the assembly, as anchoring of the stent-graft assembly is distributed along the length of the inner member.

  • Patent number: 6914960
    Abstract: An apparatus for emitting x-rays comprises a housing which contains an anode having an electron receiving surface and a cathode having an electron emitting surface. A cable couples the anode to a source of high voltage. An optical fiber secured to the cable has a proximal end coupled to a source of optical energy and a distal end configured to direct the optical energy onto the cathode's electron emitting surface. The cathode emits electrons which strike the anode to create x-ray radiation.
