Abstract
A radially expandable stent for implantation in a body blood vessel includes a pair of cylindrically shaped end portions made from a malleable metal and formed in a radially expandable fashion. According to the invention, the end portions are joined by a plurality of individual longitudinal wire members such that upon radial expansion of the stent, such as through use of a balloon catheter, the stent expands radially with a minimum of lateral shrinkage. Preferably, the longitudinal wire members are wrapped to the end portions to form flexible hinging sites upon expansion.
