  • Publication number: 20090155337
    Abstract: A method for stabilizing an extra cellular matrix layer in the vascular system of the body is disclosed herein. The method can comprise placing a vascular catheter adjacent to the extra cellular matrix layer, delivering a solution containing a bioflavonoid to the extra cellular matrix layer with the vascular catheter, and cross-linking protein in the extra cellular matrix layer. The bioflavonoid can be a catechin, particularly epigallocatechin gallate (EGCG).

  • Publication number: 20090105806
    Abstract: A tubular prosthesis can be formed by rolling a sheet of material about a longitudinal axis, thereby forming a plurality of annular rings that can be arranged so as to be longitudinally adjacent one another, thus forming a tubular prosthesis. Each annular member can expand and contract independent of the other annular members. A graft material can extend between the plurality of annular members.

  • Publication number: 20070299497
    Abstract: Disclosed is a tubular endoluminal vascular prosthesis, useful in treating, for example, an abdominal aortic aneurysm. The prosthesis comprises a self-expandable wire support structure having a tubular main body support and first and second branch supports. The support structure may include one or more sliding links to permit axial movement while maintaining patency of the central lumen. The branch supports may articulate with the main body to permit the branches to pivot laterally from the axis of the main body throughout a substantial range of motion.

  • Patent number: 6953475
    Abstract: Disclosed is a deployment catheter for deploying a tubular endoluminal vascular prosthesis, useful in treating, for example, an abdominal aortic aneurysm. The deployment catheter includes a proximal tubular section and a distal tubular section which are axially movable in opposite directions to deploy a prosthesis. A central core extends throughout the proximal tubular section and into the distal tubular section. A reinforcing structure is carried by the central core, spanning the junction between the proximal tubular section and distal tubular section, to improve flexibility characteristics of the catheter. In one embodiment, the proximal tubular section and/or distal tubular section are rotationally linked to the central core.

  • Patent number: 6951572
    Abstract: A structurally supported bifurcated vascular graft is described having a hollow cylindrical body graft with a top end and bottom end and two hollow cylindrical limb grafts which are attached to the hollow cylindrical body graft near the top end of the body graft. One or more structural supports or stents are attached to either the interior or exterior of the body graft and limb grafts. Further, an apparatus and method for delivering a one-piece bifurcated vascular graft is also described which includes first and second hollow limb tubes for containing the limbs of a bifurcated graft, a third hollow body tube for containing the body of a graft, and a hollow delivery tube capable of encompassing the limb tubes and graft body tube.

  • Patent number: 6699170
    Abstract: Disclosed is a balloon catheter having an inflatable balloon having a radiation carrier such as a radiation delivery layer thereon. In one embodiment, the radiation delivery layer comprises one or more layers of metal foil, such as gold. The foil is irradiated, and the balloon is thereafter positioned at a treatment site in a vessel and expanded to bring the metal foil layer into close proximity with the vessel wall. In another embodiment, the radiation carrier is in the form of a dopant in the balloon material. Methods of using the balloon include radiation dosing a site following a balloon dilatation or other procedure, and simultaneously performing balloon angioplasty and radiation dosing.

  • Patent number: 6689157
    Abstract: Disclosed is a dual lumen access catheter, for facilitating placement of two procedure wires across a treatment site. In one application, the catheter is used to place a first wire extending between a contralateral iliac and an ipsilateral iliac across the terminal bifurcation of the aorta, and a second wire extending through a portion of the ipsilateral iliac and into the aorta. Methods of placing the wires, such as for subsequent deployment of an abdominal aortic aneurysm bifurcation graft, are also disclosed.

  • Patent number: 6685618
    Abstract: Disclosed is a thin film radiation source, which may be used to deliver a radioactive dose to a site in a body lumen. The source comprises a thin flexible substrate, and a layer of radioisotope attached thereto. The source may further comprise additional layers such as one or more tie layers disposed between the substrate and the radioisotope layer and one or more outer coating layers. In one embodiment, the source is wrapped around an inflatable balloon. Inflation of the balloon at a treatment site positions the source directly adjacent to the vessel wall, and allows irradiation of the site following or simultaneously with a balloon angioplasty, stent implantation, or stent sizing procedure.

  • Patent number: 6491619
    Abstract: Disclosed are sources and methods for delivering a radioactive dose to a site in a body lumen. The sources are preferably mounted on a balloon or other expandable or deployable mechanical structure. The source and methods enable delivery of a clinically significant dose of radiation into a vessel wall in a relatively short time while using a relatively low activity. The sources also enable delivery of a substantially uniform dose into the vessel wall, whether or not such delivery is through the wall of a stent.
