DABRA Laser System Results Presented at 2019 NCVH Annual Conference

Dr. Kassab, FACC, FSCAI, FACP. FASA, RPVI, FAHA, FSVM, President & CEO of Michigan Outpatient Vascular Institute, Dearborn, Michigan, continued, “The device has an innate tendency to stay intraluminal in all vessels, is versatile as a single debulking device, is easy to use and is cost-effective. In our experience, DABRA has a very low complication rate and we have not seen any angiographic or clinical evidence of distal embolization.”

Dr. Kassab and Ashok Kondur, MD, recently reported that DABRA achieved a 98% lesion success rate in a 52-patient, single-center study that was summarized in the 2019 LINC Review. “Although these findings are from just 52 patients, they are very promising and strengthen the case for more extensive study of DABRA,” said Dr. Kassab.

DABRA (Destruction of Arteriosclerotic Blockages by laser Radiation Ablation) is a novel, minimally invasive excimer laser system that non-thermally and photochemically ablates channels in vascular blockages. The technology reduces all plaque types into their fundamental chemistry, such as proteins, lipids, and other chemical compounds, eliminating blockages by dissolving them without generating potentially harmful particulates. Unlike many mechanical, acoustic, or thermal treatments for peripheral artery disease (PAD) that may damage the arterial wall, DABRA treats blockages with minimal vascular trauma.

“DABRA quickly, safely, and efficiently restores blood flow, often in very difficult cases, enabling physicians to save patients’ limbs and lives,” added Dean Irwin, CEO, Ra Medical Systems.

About Ra Medical Systems

Ra Medical Systems is a commercial medical device company developing and marketing innovative excimer laser systems for the treatment of vascular and dermatologic diseases. DABRA launched in 2017 for the endovascular treatment of blockages resulting from lower extremity vascular disease and is CE marked for the indication of the endovascular treatment of infrainguinal arteries via atherectomy, and for crossing total occlusions. Pharos launched in 2004 for the treatment of dermatological disorders including psoriasis, vitiligo, and atopic dermatitis. DABRA and Pharos are based on Ra Medical’s core excimer laser technology platform that produces 308 nanometer light, a UVB wavelength that studies have demonstrated increases T-cell apoptosis, or cell death, which may produce a beneficial, targeted immunosuppressive effect. Ra Medical manufactures DABRA and Pharos excimer lasers and catheters in a 32,000-square-foot facility located in Carlsbad, California. The vertically integrated facility is ISO 13485 certified and is licensed by the state of California to manufacture sterile, single-use catheters in controlled environments.
