Abstract
An expansible balloon catheter has at least a first exterior surface with a given coefficient of friction and a second exterior surface with a greater coefficient of friction. In a compact form only the first exterior surface is exposed to produce a low coefficient of friction during transfer of the collapsed or uninflated balloon to and across a lesion. When inflated, the second surface dominates the first surface and produces an increased coefficient of friction overall thereby to stabilize the balloon in the lesion.
