  • Patent number: 6346118
    Abstract: A delivery catheter having an inner catheter assembly, an inferior capsule catheter, and a capsule jacket assembly for use in deploying a graft having a compressible and expandable attachment systems in the thoracic region of an aorta. The graft is comprised of a tubular member having superior and inferior ends, each having an attachment system with wall engaging members secured thereto and is crimped along its midsection to resist kinking and elongation. The delivery catheter includes an inferior capsule assembly for releasably retaining the inferior attachment system of the graft and a superior capsule assembly for releasably retaining the superior attachment system of the graft as well as a releasing system for maintaining the attachment systems in a compressed configuration and for facilitating expansion of the attachment systems.

  • Patent number: 6117167
    Abstract: A stent joining means is provided for joining a first endoluminal stent to a second endoluminal stent to define a continuous lumen through the first and second endoluminal stents. The stent joining means includes two transversely spaced female portions on the first endoluminal stent. The stent joining means also includes a male engaging portion of the second endoluminal stent. The male engaging portion is configured to be entered into one of the female portions in a radially compressed state and thereafter expanded in the female portion such that an outer surface of the male engaging portion and an inner surface of the female portion are interengaged to resist longitudinal movement to prevent separation of the first and second endoluminal stents in service.

  • Patent number: 5527354
    Abstract: A vascular prosthesis stent provides an interior surface that reduces hemodynamic disturbances which interfere with blood flow through the stent and minimizes the reactive tissue response. More particularly, the vascular stent is constructed from a continuous wire that is half-round (i.e., semi-circular) in transverse cross-section. In a completed stent, the semi-circular wire profiles are all on the exterior of the stent body while the planar portions of the wire are all on the interior, with the result that the interior of the stent, comprised of the cross-sectional diameters of the wires, provides a generally smooth surface that minimizes blood flow turbulence, and minimizes the amount of tissue reaction necessary to incorporate the stent into the vessel wall.

  • Patent number: 5199939
    Abstract: A method for preventing restenosis after angioplasty comprises internally radiating the treated portion of the lumen to prevent restenosis of the enlarged lumen portion. A device useful for radiating the treated portion comprises an elongated flexible catheter with radioactive means located in a distal section of the carrier. Stiffening elements are located along the length of the catheter to enable the catheter to be pushed through the tortuous segments of coronary or peripheral vasculature without crimping.

  • Patent number: 4968307
    Abstract: A vascular catheter for delivering a uniform flow of therapeutic fluid over a length of the catheter. The catheter is particularly suitable for delivering thrombolytic agents to a thrombus or clot in a patient's arterial system. In a preferred embodiment, the catheter has a relatively thick-walled tubular body with a central lumen for advancement over a guidewire and a plurality of fluid delivering lumens disposed within the relatively thick wall. Each of the smaller lumens has a single flow passageway to discharge therapeutic fluid to the exterior of the catheter.
