Atherectomy and angioplasty are methods that can be used to open arteries without surgery.

There are several different devices that can be threaded through blood vessels to the site of a narrowing or blockage. These devices remove the obstruction so that blood flow is restored.

Most often, these procedures are done when an artery is narrowed by atherosclerosis. If the artery is too narrow, blood is no longer able to pass through. The body part then suffers from lack of oxygen, also called ischemia. This can cause different symptoms, depending on the part of the body that is not getting enough oxygen.
