Abstract
An expansible balloon catheter with a stent thereon has at least a first exterior surface with a given coefficient of friction and a second exterior surface with a different coefficient of friction. In a compact form only the first exterior surface is exposed to produce one coefficient of friction during transfer of the collapsed or uninflated balloon and stent to and across a lesion. When inflated, the second surface dominates the first surface and produces a second coefficient of friction.
