1. A method for manufacturing an intravascular stent comprising:
loading a multi-element stent comprising multiple individual separate and unlinked stent elements onto an inflatable balloon in an expanded state such that the stent elements are positioned serially along a longitudinal length of the balloon and the stent elements are non-overlapping and do not touch one another, wherein the stent elements are spaced on the balloon such that after deployment the stent elements do not touch one another at a target vessel location during skeletal movement; and
deflating the balloon and crimping the multi-element stent to an unexpanded state such that each stent element lengthens and the stent elements are touching.
