  • Patent number: 8628567
    Abstract: A system for repairing body lumens including a modular graft and a method for deploying the graft within the body lumen. The modular graft includes a first component having first and second legs portions which mate with second and third graft components, respectively. The second leg portion has a bell bottom shape. The modular graft further includes expandable members which aid in implanting the modular graft as well as facilitates the mating of its components. In order to repair the body lumen, the first component is placed at the repair site and thereafter the first and second legs are advanced to the repair site and attached to the first component. A further aspect of the invention is a fixation device which is adapted to perform an attachment function. The graft and the fixation device are configured to be axially separated from one another so as to allow the graft to attach to the vascular wall proximal of the graft.

  • Patent number: 8382816
    Abstract: A new endoluminal prosthesis for use in sealing a vascular graft to corporeal lumen provides for a flattened bulbous tail at the end of each cell of the prosthesis. The flattened bulbous tails reduce the amount of wear between the prosthesis and the softer material of the vascular grafts or corporeal lumen walls. A method of manufacturing a stent from a flat sheet of material is also included.

  • 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: 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.

  • Patent number: 7942924
    Abstract: The present invention embodies delivery systems and methods of packing an initial endovascular graft components for delivery that achieve a smaller delivery profile and reduce redundancy. Delivery systems and methods for packing the initial endovascular graft components for delivery facilitate a reduced delivery profile while allowing reliable positioning of the components before deployment.

  • Patent number: 7708925
    Abstract: An apparatus for heating and setting elements of a stent. The apparatus is a mandrel having a central core cylinder with an outer surface including a plurality of raised forms and gaps in-between the raised forms. The mandrel also includes a first and second outer cylinder, each having a curved radial end with a cut-out design similar to the shape of the plurality of raised forms. Once a stent is placed on the central core cylinder, the first and second outer cylinders are positioned on the central core cylinder such that the curved radial ends of the first and second outer cylinders align with the plurality of raised forms, shaping the stent.
