  • Publication number: 20030036745
    Abstract: Methods and apparatus are provided for temporarily excluding an aneurysm or an arterio-venous fistula from a flow path by transluminally disposing a hollow balloon catheter structure within the aneurysm so that its proximal and distal ends extend past the aneurysm while maintaining continuity of the flow path, and then injecting a synthetic molding material or a biological hardening agent into the aneurysm cavity to cause solidification of the volume within the cavity. Once the material within the excluded aneurysm has solidified, the balloon catheter structure is deflated and removed, so that the hardened mass forms a new lining for the organ or vessel, and relieves the weakened tissue of the aneurysm or fistula from further flow-induced stress.

  • Patent number: 6378218
    Abstract: Methods and apparatus are provided for converting standard catheters or balloon catheters into drug infusion devices on an as-needed basis in a sterile environment, and which permit re-use of catheter devices previously used in a preceding non-invasive procedure. Apparatus is provided having a cavity for receiving a catheter device and a plurality of perforation pins or teeth for creating apertures in the catheter. Apparatus capable of converting a wide range of catheter devices into drug infusion devices is provided, which apparatus may be single-use disposable or re-sterilizable and re-usable.

  • Patent number: 5824055
    Abstract: A stent-graft delivery system and methods for use are provided for use in treating aneurysms occurring in single and bifurcated lumen hollow-body organs or vessels and for treating arterio-venous fistulas. A graft delivery component provides a clinician with complete control over the location of a graft at any time prior to implantation of stents, even when the graft is deployed from its introducer catheter. The graft delivery component includes a plurality of radially expandable fingers that releasably engage the graft, while the stent delivery component includes a small diameter introducer catheter and permits a wide range of conventional stent designs to be used to permanently fix the graft in position.
