摘要
An intravascular device can comprise a carrier and an expansion apparatus. The device can be used for intravascular treatment of atherosclerotic plaque. The carrier can be reversibly expandable and collapsible within a vessel and can have ribbon strips extending between opposite ends in a longitudinal direction of the carrier. The ribbon strips can each be formed with a plurality of elongated protrusions thereon. The expansion apparatus can be used to actuate the ribbon strips each with the plurality elongated protrusions to pierce a luminal surface of the plaque with lines or patterns of microperforations which act as serrations for forming cleavage lines or planes in the plaque.
