The NIR Imaging System is a novel tool that interventional cardiologists can use to obtain additional information about coronary artery plaques. The catheter is designed to be similar to an IVUS catheter with respect to usability. However, the NIR catheter provides information about the composition of the plaque.

The catheter obtains this information by sending NIR light into the plaque, and transmitting the reflected light to detectors. The amount of light reflected at different wavelengths provides information about the chemical composition of the plaque. An algorithm has been developed to analyze this light and create a map of the results that has been designated as an Intravascular Chemogram™. The physician can add the results of the Intravascular Chemogram™ to other information that might be used in the management of the patient.

It is expected that the NIR system will initially be used in patients undergoing a percutaneous coronary intervention who already have a guidewire in place in their coronary circulation. The NIR results will be added to the information used to help the cardiologist with patient care.

Interventional cardiologists who would like to participate in an ongoing InfraReDx clinical study, or utilize the InfraReDx device in a study they initiate, should contact Steve Chartier, Vice President of Clinical and Regulatory Affairs at the Company.

Physicians who do not perform interventional procedures may find the InfraReDx device of interest as a potential test that might be performed for primary prevention in individuals identified to be at very high risk due to clinical characteristics, the results of blood tests and non-invasive testing.

It is expected that the InfraReDx device will be of greatest initial interest to hospitals that have a large interventional cardiology program that seeks to provide the most recent technology for the patients being studied. The ability of the NIR system to provide additional information about the composition of atherosclerotic plaque on the arterial wall will help in the delivery of more personalized management.
