  • Publication number: 20070010875
    Abstract: An insertion apparatus comprises an introducer sheath, a surgical component, at least two attachment wires, and a longitudinal wire. The insertion apparatus is used for deploying a surgical component to a site in a vessel. The introducer sheath has a lumen, a proximal opening and a distal opening with an appropriate diameter and length allowing fro insertion and navigation through the vessel. The surgical component has a tube portion with a top and at least one limb. The surgical component corresponds to the site in the vessel and fits within the lumen of the introducer sheath. The attachment wires have a first and a second end. The first end is releasably connected to the top of the surgical component and the second end converges above the top of the surgical component. The activation of a releasing mechanism releases the first end from the top of the surgical component.

  • Publication number: 20050043785
    Abstract: An attachment assembly and repair graft are disclosed for securing a graft to repair a vessel having an aneurysm therein. The attachment assembly comprises an attachment cuff such that the graft is not dimensionally dependent upon the size of the vessel. A visualization apparatus is also disclosed for real time direct viewing of an interior of a vessel. A penetration apparatus is disclosed for use in forming treatment specific holes in a potentially calcified vessel wall which facilitates thereafter the securing of the graft and attachment assembly to the vessel wall. An introducer sheath device is also disclosed that comprises a sealing assembly for preventing the loss of blood from the vessel during the insertion and subsequent removal of surgical components during the surgical procedure.
