Abstract

A device and method for intravascular treatment of atherosclerotic plaque prior to balloon angioplasty. An intravascular device can comprise a carrier configured for expansion within a vessel. The carrier can have a s plurality of ribbon strips extending longitudinally between a first end and a second end. An open slot can be positioned between adjacent ribbon strips. A plurality of spikes can be positioned on each of the ribbon strips. The spikes can act as serrations for forming cleavage lines or planes in plaque in the vessel. The spikes may also be used to transport medication into the plaque. The plaque preparation treatment can enables subsequent angioplasty to be performed at low balloon pressures, can reduces dissections, and avoids injury to the arterial wall.
