1. A method of making an intravascular stent, comprising the steps of:
a. vacuum depositing a metal hypotube onto a cylindrical substrate;
b. patterning a stent pattern onto the deposited metal hypotube, wherein the pattern comprises a plurality of longitudinally extending struts defining a plurality of interconnected closed cells connected to each other along a first circumferential axis of the metal hypotube by interconnection points, and a plurality of elongate struts defining a plurality of bridge struts, each of the plurality of bridge struts extending along a second circumferential axis and having opposing ends that interconnect at the interconnection points between adjacent pairs of the plurality of interconnected closed cells at each opposing end of each of the plurality of bridge struts; and
c. removing the stent pattern from the cylindrical substrate.
