  • Intravascular stent
    Patent number: 6846323
    Abstract: An intravascular stent assembly for implantation in a body vessel, such as a coronary artery, includes undulating circumferential rings having peaks on the proximal end and valleys on the distal end. Adjacent rings are coupled together by links. The rings and links are arranged so that the stent has good conformability as it traverses through, or is deployed in, a tortuous body lumen. The stent is also configured such that the likelihood of peaks and valleys on adjacent rings which point directly at each other to overlap in tortuous body vessels is reduced.
    Type: Grant
    Filed: May 15, 2003
    Date of Patent: January 25, 2005
    Assignee: Advanced Cardiovascular Systems, Inc.
