Abstract
A balloon catheter is provided that may be used to dilate hardened regions of a stenosis. The balloon catheter is provided with dilation elements that extend along a surface of a balloon. The dilation elements may comprise a coil and dilation wire. The coil and wire may be configured in various ways such that inflation of the balloon creates a concentration of forces along the dilating wires which are thereafter transmitted to stenosed regions of a vessel wall. The force exerted by the dilation elements against the stenosed region is sufficient to fracture plaque from the vessel wall.
