There are two phases to the RESTORE Procedure. The first is a diagnostic phase with the completion of a 15 minute angiogram procedure. The patient is placed under an x-ray camera, where our physicians introduce a small catheter through the radial artery in the wrist and navigate the catheter to the pelvic arteries. When in the appropriate blood vessels they inject dye to get a road map of the blood flow. With this diagnostic study our physicians can identify blockage in either one or both arteries supplying blood flow to the penis.
