  • Expandable stents and method for making same
    Patent number: 5916234
    Abstract: The invention is directed to an expandable stent for implantation in a body lumen, such as an artery. The stent consists of a plurality of radially expandable cylindrical elements generally aligned on a common longitudinal stent axis and interconnected by one or more interconnecting members placed so as to limit longitudinal contraction during radial expansion. The individual radially expandable cylindrical elements are formed in an irregular serpentine pattern designed to expand evenly under radial stress, and maximize the overall radial expansion ratio.
    Type: Grant
    Filed: July 21, 1997
    Date of Patent: June 29, 1999

  • Radiopaque stent
    Patent number: 5725572
    Abstract: A radiopaque marker associated with a stent which is adapted to be implanted into a patient's body lumen to maintain the patency thereof and a convenient and accurate method for affixing the radiopaque marker to the stent. The radiopaque marker defining an acceptable profile and capable of facilitating, under fluoroscopy, the identification of the position, diameter and length of a stent without obscuring the lesion being repaired and without impeding the deformation of an expandable stent.

  • Expandable stents and method for making same
    Patent number: 5569295
    Abstract: The invention is directed to an expandable stent for implantation in a body lumen, such as an artery. The stent consists of a plurality of radially expandable cylindrical elements generally aligned on a common longitudinal stent axis and interconnected by one or more interconnecting members placed so as to limit longitudinal contraction during radial expansion. The individual radially expandable cylindrical elements are formed in general serpentine pattern designed to expand evenly under radial stress, and maximize the overall radial expansion ratio.
