Artery's clearance post surgery

An artery is blocked by the cholesterol content(70%). A bio-absorbable stent is moved in and artery is cleared.

Does it mean, the cholesterol is cleared or taken out?
OR
the artery is just widened such that the walls/edge along with the cholesterol is pushed up?

How is the artery actually cleared and blood flow is made easy?

When a stent is placed, it basically crushes the cholesterol plaque into the wall of the artery. It doesn't make the artery itself wider, it just allows the lumen of the artery to be the width it is supposed to be.
