  • Stent pattern with figure-eights
    Publication number: 20040172128
    Abstract: The invention is directed to an expandable stent for implanting in a body lumen, such as a coronary artery, peripheral artery, or other body lumen. The invention provides for an intravascular stent having a plurality of cylindrical rings connected by links. The rings have peaks and valleys from which extend straight and nonlinear bar arms, forming a figure-eight The links connecting the cylindrical rings may be straight, undulating, or include bounded apertures for additional flexibility.
    Type: Application

  • Intravascular stent
    Publication number: 20030199968
    Abstract: The invention is directed to an expandable stent for implantating in a body lumen, such as a coronary artery, peripheral artery, or other body lumen. The invention provides for a an intravascular stent having a plurality of cylindrical rings connected by undulating links. The stent has a high degree of flexibility in the longitudinal direction, yet has adequate vessel wall coverage and radial strength sufficient to hold open an artery or other body lumen.

  • Intravascular stent
    Patent number: 6626935
    Abstract: This invention is directed to an expandable stent for implanting in a body lumen. The invention provides for an intravascular stent having cylindrical rings and a plurality of flexible spring joints linking the rings together. The flexible spring joints enable components of the stent to be large enough to provide excellent radiopaque and vessel supporting capabilities. The stent is flexible along its length and about its longitudinal axis while maintaining stiffness in the radial direction in order to resist collapse once implanted.
