  • Low profile medical stent
    Patent number: 8491647
    Abstract: A medical prosthesis having a low profile for delivery into a body lumen is disclosed. The stent includes a plurality of wire strands woven to form a plurality of joints at the intersections, some of which are helically wrapped. The helically wrapped joints may be offset form the joints of a second plurality of wire strands concentric to the first. Alternatively, the helically wrapped joints can doubled forming box nodes.
    Type: Grant
    Filed: June 12, 2012
    Date of Patent: July 23, 2013
    Assignee: Boston Scientific Scimed, Inc.
    Inventors: Darragh Colgan, Peter A. Hamilton, Paul DiCarlo, Andrew J. Campbell, Sean Gilligan, Albert Chin, Kristian DiMatteo

  • Low profile medical stent
    Patent number: 8197528
    Abstract: The present invention relates to a medical prosthesis having a low profile for delivery into a body lumen. The stent includes a plurality of geometric cells defining the stent, which has first and second opposed open ends; and a plurality of wire strands woven to form a plurality of crossed regions defining the geometric cells. Each wire strand has strand ends and the strand ends are disposed at the second end of the stent.

  • Stent delivery system
    Patent number: 7172617
    Abstract: The present invention relates to a system for delivering a medical prosthesis into a body lumen. A preferred embodiment of the invention utilizes a catheter having a stent mounted at the distal end that is released into the body lumen by movement of an outer sheath covering the stent in the proximal direction. The stent expands to conform to the inner wall of the lumen and the catheter is withdrawn.

  • Low profile medical stent
    Patent number: 6264689
    Abstract: The invention relates to an implantable medical stent having a low profile for delivery through smaller lumens. The stent is constrained during delivery where the helically wrapped points of a diamond cell structure also include at least one crossed joint of intersecting strands to provide a reduced diameter.
