  • Patent number: 11779479
    Abstract: An endovascular delivery system includes a bifurcated and inflatable prosthesis including a main tubular body having an open end and opposed ipsilateral and contralateral legs defining a graft wall therein between. A tether is disposed securably disposed to the contralateral leg, and the contralateral leg is releasably restrained towards the ipsilateral leg tether to prevent undesirable movement of the contralateral leg. A release wire within the endovascular delivery system releasably retains the tether near the ipsilateral leg.

  • Patent number: 11717391
    Abstract: Systems and methods for treating diseased bodily lumens involving branched lumen deployment sites include a main graft or stent-graft deployable in a main artery and a vent device or stent-graft deployable in a branch artery to maintain blood flow through the main artery and from the main artery to the branch artery. Systems and methods for treating diseased bodily lumens involving branched lumen deployment sites may also include a main graft or stent-graft deployable in the main artery, a chimney graft or stent-graft deployable in both branch artery and the main artery to the branch artery and a gutter-sealing device associated with the chimney graft to prevent flow of blood among the chimney graft, the main graft and a wall of the main artery.

  • Patent number: 11439497
    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: 20220071785
    Abstract: A tandem modular endograft includes a main elongate tubular graft body having at least one circumferential inflatable channel disposed towards a proximal portion of the graft body wall and a plurality of circumferential inflatable channels disposed towards a distal portion of the graft body wall. A proximal expansion anchor is disposed at or secured to a proximal neck portion of the graft body wall. First and second elongate tubular stent-graft extensions may be percutaneously disposed into a distal end of the tubular graft body. In combination, proximal portions of the first and second stent-graft extensions are conformable to a shape of the open lumen of the main graft body.
