  • Patent number: 7374570
    Abstract: A polymer composition for use in forming a stent is described. The composition includes a monomer of an aliphatic ester of acrylic acid which has a glass transition temperature less than 25° C. and a second monomer that copolymerizes with the first monomer and which has a glass transition temperature greater than 25° C. The components in the composition are mixed in amounts suitable to give a copolymer having a glass transition temperature less than 25° C., or in case of block copolymers, having at least one glass transition temperature less than 25° C. A stent including polymer members formed from the described composition is also disclosed.
    Type: Grant

  • Patent number: 6168619
    Abstract: A radially-expandable stent for insertion into a lumen is described. The stent is composed of a radially-expandable support stent and a polymer tubular member co-axially disposed over the support stent. Tubular end sleeves are disposed around the first and second ends of the polymer-surrounded support stent to secure the tubular member and to provide other improvements.
