  • Publication number: 20190151070
    Abstract: A system for placement in at least one blood vessel includes a main graft body, one or more inflatable channels, and a filling structure. The one or more inflatable channels are attached to the main graft body. The filling structure is inflatable around at least a portion of the main graft body and at least a portion of at least one of the one or more inflatable channels. Various systems further include a graft extension that is insertable into a lumen formed by the main graft body, where the filling structure is inflatable around at least a portion of the graft extension. A method includes inserting a main graft body into a blood vessel, filling an inflatable channel attached to the main graft body, and filling a filling structure to inflate around at least a portion of the main graft body and at least a portion of the inflatable channel.

  • Publication number: 20080027530
    Abstract: A joint and method for producing a joint in an endovascular graft. In one embodiment, a flap of a flexible material portion of an endovascular graft is folded about a portion of an expandable member to form a loop portion. The flap is secured in the loop configuration so that tensile force on the expandable member is transferred into a shear force on the fixed portion of the flap.

  • Publication number: 20070012396
    Abstract: A device and method for the manufacture of medical devices, specifically, endovascular grafts, or sections thereof. Layers of fusible material are disposed upon a shape forming member and seams formed between the layers in a configuration that can produce inflatable channels in desired portions of the graft. After creation of the seams, the fusible material of the inflatable channels may be fixed while the channels are in an expanded state. A five axis robotic seam forming apparatus may be used to create the seams in the layers of fusible material.

  • Publication number: 20060224232
    Abstract: A hybrid modular endovascular graft wherein a main graft is sized to span at least a portion of a target vessel lesion in a large percentage of patients. Graft extensions may be secured to the main graft to extend the main graft and provide a sealing function for some applications.

  • Publication number: 20060224227
    Abstract: A catheter for delivery of an expandable intracorporeal device and method of using the catheter. The catheter may have an elongate shaft with a proximal section, distal section, proximal end and distal end. The distal section has a radially expandable shear barrier which is at least partially radially constrained by an outer radially constraining section. An expandable intracorporeal device, specifically an expandable endovascular graft, is disposed within an inner space within the radially expandable shear barrier. The catheter is guided to a desired site within a patient's body and the radial constraint of the outer radially constraining section is at least partially removed from the radially expandable shear barrier so as to allow the shear barrier and expandable intracorporeal device to expand and deploy.

  • Publication number: 20060178732
    Abstract: This invention is a system for the treatment of body passageways; in particular, vessels with vascular disease. The system includes an endovascular graft with a low-profile delivery configuration and a deployed configuration in which it conforms to the morphology of the vessel or body passageway to be treated as well as various connector members and stents. The graft is made from an inflatable graft body section and may be bifurcated. One or more inflatable cuffs may be disposed at either end of the graft body section. At least one inflatable channel is disposed between and in fluid communication with the inflatable cuffs.

  • Publication number: 20060173533
    Abstract: An endovascular graft, which is configured to conform to the morphology of a vessel to be treated, includes a tubular ePTFE structure; an inflatable ePTFE structure disposed over at least a portion of the ePTFE tubular structure; and an injection port in fluid communication with the inflatable ePTFE structure for inflation of the inflatable ePTFE structure with an inflation medium. The inflatable ePTFE structure may be longitudinally disposed over the tubular ePTFE structure. The ePTFE structure may be a bifurcated structure having first and second bifurcated tubular structures, where the inflatable ePTFE structure is disposed over at least a portion of the first and second bifurcated tubular structures.

  • Publication number: 20060009833
    Abstract: A flexible low profile delivery system for delivery of an expandable intracorporeal device, specifically, an endovascular graft, which has at least one belt circumferentially disposed about the device in a constraining configuration. The belt is released by a release member, such as a release wire, by retracting the wire from looped ends of the belt. Multiple belts can be used and can be released sequentially so as to control the order of release and placement of the endovascular graft. An outer protective sheath may be disposed about the endovascular graft while in a constrained state which must first be retracted or otherwise removed prior to release of the graft from a constrained state. The delivery system can be configured for delivery over a guiding device such as a guidewire. The delivery system can also be configured for delivery of bifurcated intracorporeal devices.

  • Publication number: 20050090804
    Abstract: The present invention provides methods and compositions for managing endoleaks in a perigraft space around an endovascular graft. In one embodiment, a blood flow through the endovascular graft is temporarily reduced and an embolic material is delivered into the perigraft space while the blood flow through the endovascular graft is reduced. The embolic material may comprise polyethylene glycol diacrylate, pentaerthyritol tetra 3(mercaptopropionate), and a buffer.
