1. An intravascular device comprising:
an inner balloon configured to expand to create a plurality of microperforations in a vessel wall of a vessel, the inner balloon comprising a plurality of strips, each strip of the plurality of strips including a plurality of microperforators spaced apart along a surface of each strip, each strip extending along an outer surface of the inner balloon, wherein expanding the inner balloon forms cleavage lines or planes in an atherosclerotic plaque of the vessel wall,
wherein the inner balloon forms microperforations while leaving most of the surface of the atherosclerotic plaque intact, leading to less separation of the atherosclerotic plaque from the vessel wall,
an outer balloon disposed circumferentially around the inner balloon, wherein the inner balloon extends for a length beyond the outer balloon, wherein the plurality of microperforators extend through the outer balloon to form cleavage lines or planes in an atherosclerotic plaque of the vessel wall, wherein the plurality of microperforators are not configured to deliver a fluid from within the intravascular device out to the vessel.
