1. A device for treating vulnerable plaque, comprising a balloon catheter having a wingless self-limiting balloon with an unexpanded diameter which inflates to a limited, controlled expanded diameter, and the balloon has at least one layer of porous polymeric material with an antithrombotic agent within the pores, and wherein such expanded diameter is selected to intentionally damage such plaque by disrupting a fibrous cap without cap rupture, to thereby strengthen the vulnerable plaque by inducing extracellular matrix protein synthesis.
