Several other devices may be used during an Angioplasty. One is a rotating burr (Rotablator) that helps clean out plaque in a coronary artery. The Directional Coronary Atherectomy device uses a rotating cutter to ‘shave off’ pieces of the arterial blockage. Sometimes, special ‘cutting’ balloons are also used to open the arteries. Laser beams have been tried, but with less success.
The latest in Angioplasty:
In some cases, although a coronary artery has been fully opened blood does not flow through it because, superfine plaque debris could block very small blood vessels. To obviate this problem, the ‘Distal Protection Device’ removes the fine plaque debris by using a balloon or filter device.
