  • Patent number: 8535370
    Abstract: An endovascular prosthesis containing radiopaque markers for identifying the position of the prosthesis and for detecting any twisting of the prosthesis inside a corporeal vessel. The prosthesis may be a graft having a graft body with a wall defining a lumen. A plurality of radiopaque markers are disposed on the wall of the graft, with each individual marker appearing identical under fluoroscopy regardless of the grafts orientation inside the corporeal vessel, but the relative positions of individual markers relative to each other in a set indicate the prosthesis position and orientation.

  • Patent number: 8211139
    Abstract: A graft provided with a flexible sealing member to substantially prevent blood from leaking between the graft a lumen into which the graft is placed. In one embodiment, the flexible sealing member may be pressed against the vascular wall by an outwardly biased spring means attached to the sealing member. In other embodiments, the sealing member may be self-positioning upon deployment of the graft. The sealing member also may be formed into the shape of a toroid, which may be filled with thrombogenic material causing blood permeating into the toroid-shaped space to coagulate therein and hold the sealing member in place. It is also contemplated that the sealing member be formed from tufts of frayed yarn protruding circumferentially from the outer surface of the graft. A method of manufacturing such tufted yarn sealing members is also disclosed.

  • Patent number: 8177833
    Abstract: The present invention provides a system and a method for forming in vivo a junction between a first and a second element of a modular endovascular prosthesis used for repairing defects in vessels and other lumens within the body of a patient. The first element is adapted to have a receiving element, and the second element is adapted to have a protruding element. In the final deployed configuration of the endovascular prosthesis, the protruding element of the second element is adapted to be engaged with the receiving element of the first element, substantially preventing axial separation of the elements relative to each other. The receiving element of the invention may have various forms, and may include a fold in the wall of the first element, an expandable framework having protruding struts, or a flexible thread.

  • Patent number: 8118864
    Abstract: An endovascular graft of the present invention embodies a graft system utilizing the textile fabric of the prosthesis for drug storage and delivery. These drug-eluting devices involve treating the textile fabric with therapeutic agents to provide a method of delivery to both the outer surface of the graft and the inner surface of the graft. An endovascular graft system having a fuzz texturing on the outer periphery of the graft where the texturing includes a therapeutic agent coating applied to the texturing material is also contemplated. An expandable attachment frame further includes drug storage and delivery capabilities in the cavities formed in the V-hooks and apices. Therapeutic agents can also included in the radiopaque coating or loading to serve as a reservoir for controlled drug delivery.

  • Patent number: 8109992
    Abstract: A stent shaped as a three-dimensional body which is formed by interlaced threads (1) arranged in multistart turns of a helical line. The threads (1) are arranged in at least two groups (2 and 3) of the helical turns featuring opposite senses of helix. The stent ends are established by sections (5) where the turns of one helical line merge into those of the other helical line, said sections appearing as a single length of the thread (1).

  • Patent number: 8021404
    Abstract: Fibrosis, in at least one layer of a vessel wall, can be used to strengthen a vessel wall. Fibrosis can be induced by irradiating a vessel wall with an energy source, or by inducing injury to the vessel wall. In addition to an energy source, photoactivatable agents can also be used such that the energy activates the photoactivatable agent to cause a thickening of the vessel wall. For example, ultra-violet radiation can be used alone or in conjunction with a photoactivatable agent, such as a psoralen compound, to increase the adventitial volume of a blood vessel. Upon exposure to radiation, preferably ultra-violet A radiation, the photoactivatable agent becomes activated and causes compositional and/or structural changes in the adventitia. The invention provides a method of treating aneurysms by thickening the adventitial layer of the vessel wall at the site of the aneurysm.

  • Patent number: 7998194
    Abstract: An improved hood provides for the attaching of endoluminal prosthesis within corporeal lumens. The hook is integrally formed with framing structure and is preset into an outward bend, but is resiliently flexible so as to form a substantially straight profile when compressed. The hook is capable of impinging upon the corporeal lumen and thereby securing the prosthesis. The hook may be configured for intraluminal delivery and deployment. A novel method of manufacturing said hook is also provided.
