atherectomy


An atherectomy is a procedure to remove plaque from arteries. An ultra-thin wire is threaded through a special catheter into the blocked artery. Several devices may then be used: a high-speed rotating "burr" that grinds the plaque into tiny pieces; a small rotating cutter that "shaves off" pieces of the blockage; or a laser catheter that vaporizes the plaque.
