  • Patent number: 6660030
    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: 6582467
    Abstract: Disclosed is an expandable fusion cage which facilitates the fusion of adjacent bony surfaces, preferably those in the spine. In a preferred embodiment, the fusion cage. The surfaces of the cage which are intended to contact the vertebral endplates have multiple portions cut out of the metal to form sharp barbs. As the cage is expanded to come into apposition with endplates above and below, the sharp barbs protrude into the subcortical bone of the vertebral body thus securing the cage in place. Multiple holes or fenestrations are present on the superior and inferior surfaces of the cage to permit contact of morselized autologous bone and/or an artificial bone matrix material with the prepared endplate surface.

  • Patent number: 6440161
    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.

  • Publication number: 20020052644
    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 sliding links to permit flexibility 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. Exoskeleton components or barbs may be provided to resist migration and endoleaks.
