"DABRA’s US market clearance is the realisation of more than a decade of dedication to the pursuit of delivering a more effective, safer and less expensive way to remove blockages from arteries to save limbs and, ultimately, save lives."

“To do so, we built Ra Medical Systems and pioneered our cost-effective, small and portable Pharos excimer laser for dermatological diseases, creating our company infrastructure and self-funding the development of DABRA.”

Expected to result in interventional procedures and better patient access, DABRA is said to require less procedural time, when compared to existing arterial blockage treatments.
