Have patients already been treated with Reducer™?

The Reducer System has been approved in many other countries around the world, but has not been approved for use in the United States. To date, over 2,000 patients have had the Reducer device implanted. Neovasc hopes COSIRA-II will provide the necessary data for the Food & Drug Administration (FDA) to approve the device to treat patients in the United States.

How do patients respond?

Relief varies by patient and depends on a number of factors. Many patients who have had the Reducer implanted report relief from angina symptoms sometimes as early as 6 weeks after the procedure, with most patients reporting improvement within 3 months.
