1. A composition for use in forming a polymeric stent for insertion into a vessel, comprising between 10-98% of a first monomer composed of an aliphatic ester C1-C50 of acrylic acid which when homopolymerized has a glass transition temperature lower than about 25°

  • C.; and

    a second monomer having sites of unsaturation and capable of copolymerization with the first monomer, the second monomer when homopolymerized having a glass transition temperature greater than 25°

    C., said monomers when polymerized in the presence of a crosslinker forming a polymer having a glass transition temperature of less than about 25°

    C.
