New Study Shows DABRA Laser System Achieved 94% Success Rate in Patients with Peripheral Artery Disease

CARLSBAD, Calif.--()--Ra Medical Systems, Inc. (NYSE: RMED), today announced study results from Athar Ansari, MD, Director of the California Heart & Vascular Clinic, who stated, “DABRA is fundamentally changing the way I practice medicine.” Dr. Ansari’s study demonstrated a 94% success rate treating peripheral artery disease (PAD) by ablating arterial blockages. He presented his findings at this year’s Joint Interventional Meeting in Milan, Italy.

In Dr. Ansari’s study, 292 lesions were treated in 200 patients at his outpatient office-based lab in El Centro, Calif., an area with high diabetes, peripheral artery disease, and amputation rates. “In my experience, DABRA delivers results rapidly and safely, even in challenging cases,” said Dr. Ansari. “DABRA can treat all types of plaques in arteries above and below the knee. Patients are discharged in two to three hours, allowing them to quickly return to their daily lives. Most importantly, DABRA meets the need for safe, high-quality tools in smaller-scale settings, including office-based labs, allowing me to spare patients from hospital stays and reduce costs.”

DABRA (Destruction of Arteriosclerotic Blockages by laser Radiation Ablation) is a novel, minimally invasive excimer laser system that non-thermally, photochemically ablates channels in vascular blockages. Unlike many treatments for PAD that may damage the arterial wall, DABRA treats blockages with minimal vascular trauma.

“We believe Dr. Ansari’s study and experience are further evidence that DABRA benefits patients, physicians, and the healthcare system as a whole,” added Dean Irwin, Ra Medical Systems CEO. “We are delivering on our mission to provide physicians a better treatment to save limbs and lives in the U.S. and around the world.”
