    摘要: 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.

    摘要: Described is an inflatable implant suitable for placement in the human body and left there for an indeterminate and potentially lengthy period of time. The implant is one that has a low profile when introduced into the body and a larger profile when it is inflated with one or more filler materials. Depending upon design and use choices the delivered implant may be removable and adjustable in situ in size, position, location, form, and rigidity. Indeed, in some variations, the design of the implant may be such that it may be removed at a potentially fairly lengthy time after implantation. The implant includes at least one bladder wall that generally is at least partially non-elastic (or unexpandable) after the preselected size is reached. The bladder wall will define at least one fillable volume and may form more than one independent fillable volumes. The bladder wall, in some variations, may be partially elastic or expandable to permit adjustment of implant size or configuration after or during delivery. The implant may be used as a supporting structure in a variety of differing body tissues and structures, e.g., in the spine or as a prosthetic in plastic surgery. The implant may also be used in conjunction with other components (often having a springed bias) as a source of movement in controlling the opening of a lumen or duct, that is to say, as a type of on-off valve or as a controlled flow valve. The implant may be used as an occludant within, or adjacent to, a variety of natural or abnormal anatomical body openings, e.g., vascular and genital lumina, aneurysms, ducts, septal defects, fistulae, esophagus, etc. The wall and filler material may be selected to deliver treatment materials the locale of the implant site or to remove amounts of harmful materials from such a region. The implant may, with an appropriate filler material or bladder wall material, be used in cooperation with an appropriate radio frequency (RF) source to cause the increase of a localized internal temperature and a resulting tissue change such as coagulation, ablation, or the like. Methods of using the implant are also described.

    摘要: 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.

    摘要: 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.

    摘要: A medical device includes an elongate metallic hypotube having an open proximal end and an opposed open distal end defining a tubular wall having an open internal diameter and an exterior diameter. The tubular wall has a first flexible portion disposed near the proximal open end and a second portion disposed near the distal open end. The first flexible portion of the hypotube includes a plurality of slots extending through the tubular wall and having a circumferential arc from about 150° to about 300°; and where adjacent slots are axially offset from one and the other from about 30° to about 60°. The medical device may be used as part of an endovascular delivery system.

    摘要: Some embodiments relate in part to endovascular devices such as prostheses and methods of testing same prior to deployment. Some embodiments may be directed more specifically to inflatable grafts or stent grafts and methods of in vitro leak testing of such grafts prior to in vivo deployment.
