A fiber optic catheter....initial use will be for diagnosis purposes initially for patients who have already had treatments to help in prevention of a second coronary event...an analysis of the chemical content of the plaque....will find lipid rich plaque at each segment...the video at the site will explain more...fibrotic plaque and lipid rich can be differentiated with the process....BD
The U.S. Food and Drug Administration has cleared for marketing a device that a doctor can use to see inside a blood vessel to assess the fat content of the plaque which builds up on the wall of the coronary arteries.
Plaque is a deposit made up of cholesterol-rich fat, calcium, and other substances found in the blood. As plaque accumulates on the artery wall, it reduces blood flow to the heart muscle and increases the risk of blood clots which can lead to a heart attack.
The InfraReDx system consists of a laser light source, an automated pullback and rotation device and a small fiberoptic catheter. While the catheter is similar in size and ease of use to an intravascular ultrasound catheter, the information it provides is quite different since it is based on an optical rather that an ultrasonic signal.
