Solution Overview

The ROX Coupler is placed between the artery and vein in the upper thigh to allow a calibrated amount of blood to flow between them, known as an anastomosis. The minimally invasive catheter procedure to place the Coupler is known as the FLOW procedure. The FLOW procedure is performed in a Cardiac or Radiology catheterization lab, takes about one hour, and does not require sedation. The procedure is fully reversible by placing a covered stent over the arterial side of the anastomosis.

The ROX Coupler is intended for use in patients with treatment resistant hypertension and may lower blood pressure by reducing peripheral vascular resistance and improving vascular compliance.

The ROX Coupler has also been studied in patients with severe and very severe Chronic Obstructive Pulmonary Disease (COPD). In these patients, its potential benefits may include improved breathing, reduced symptoms of chronic bronchitis, and improved exercise tolerance. It is possible that the procedure may increase the oxygen content (CaO2) in patients with hypoxemia, and the cardiac output (CO), thereby increasing oxygen delivery to tissues (DO2). COPD patients may be able to walk farther, experience reduction in their severe COPD symptoms, and their quality of life may improve.
