No Guidewire

    The DABRA catheter is a device designed to be used without a guidewire. Most doctors question whether it's feasible until they try it and realize it works, and may contribute to its safety profile.

    Tracks True Lumen

    The DABRA catheter tends to track the true lumen even while ablating tough calcified lesions without a guidewire in front.

    Forward Cutter

    The DABRA catheter is designed as a forward cutting device. It tends to spare the vessel wall from damage, which improves safety and lowers the rate of perforation and subintimal penetration.


    The DABRA Catheter is a forward-cutter, designed to ablate a channel through a vascular blockage. DABRA is a high fill-factor liquid filled 1.5mm catheter which transmits the laser energy to molecularly ablate plaque, turning it into its own fundamental chemistry, not showering debris downstream.


    We believe that our liquid-filled, full-aperture ratio catheter allows for a less traumatic endovascular treatment for the removal of vascular blockages and offers significant benefits over competing treatments and therapies.


    The wavelength of the emitted light is the result of a pulsed high-energy electrical current that is passed through a gas mixture in what’s called an Excimer laser.


    DABRA catheters are disposable and packaged in a standard endovascular pouch. The DABRA Laser System lightsource is small enough for any treatment room, intuitive to use, and uses a standard 110-volt outlet.


    What Is An Excimer Laser?

    An XeCl laser that emits pulses of ultraviolet light at 308 nm.

    The DABRA Laser System accommodates a DABRA catheter to deliver the laser energy to the arterial blockage. Operating parameter ranges for this excimer laser system are fluence between 8 and 15mJ/mm2 and pulse repetition rates between 20 and 80 pulses per second. Excimer a contraction of "excited dimer." Excimer lasers are a class of gas-discharge lasers, in which pulsed high energy electrical current is passed through a gas mixture. In excimer lasers, the mixture contains a rare gas (Ar, Kr, or Xe) and a halogen (Cl or F).The wavelength of the emitted light is determined by which rare gas-halogen pair are in the mixture.Most excimer lasers emit in the ultraviolet region, generally between 350 and 193 nm.

    Excimer Laser Development

    From 1975-1979 many scientists and institutions worked on the initial development of a family of gas lasers known as the "excimer."

    Those pioneers were with institutions including Lumonics, Lambda Physik, Avco, and Caltech. The development was initiated in part because of the short wavelength of this type of light source. Monochromatic short wavelength sources were thought to have a variety of commercial, medical, and military applications.


    The name excimer is a contraction of "excited dimer." The important gas molecules are rare gas halides including argon fluoride, krypton fluoride, and xenon chloride. The ultraviolet light from an excimer laser is well absorbed by biological matter and organic compounds. Rather than burning or cutting material, the excimer laser adds enough energy to disrupt the molecular bonds of the surface tissue, which effectively disintegrates in a tightly controlled manner through ablation rather than burning. These properties make excimer lasers well suited to precision micromachining organic material, or delicate surgeries such as eye surgery. At lower energy densities, the laser may also be used for dermatological disorder treatment.


    In the early 1980s, researchers at IBM’s T. J. Watson Research Center observed the effect of the ultraviolet excimer laser on biological materials. They found that the laser made clean precise cuts that would be ideal for delicate surgeries. Subsequent work introduced the excimer laser for use in angioplasty or atherectomy, ablating blockages in arteries.. Xenon chloride excimer lasers, having a wavelength of 308nm, can also treat a variety of dermatological conditions including psoriasis, vitiligo, atopic dermatitis, and leukoderma.

    Excimer Laser Atherectomy

    In the late 1980s, 308nm excimer laser photoablation (atherectomy) was developed as an alternative method of percutaneous angioplasty, with the objective of reducing the high rate of restenosis associated with other angioplasty or stenting techniques.

    Excimer laser photoablation (atherectomy) is a procedure that utilizes an intravascular catheter system to deliver high-energy pulsed laser light to atherosclerotic lesions, or plaque, that are causing stenosis or occlusion of native arteries, or intra-arterial stents, while producing relatively little thermal damage to the vessel wall. The pulses ablate thin sections of tissue without causing significant damage to surrounding tissue. It is thought that reduction of plaque using laser ablation could be more effective in enlarging the vessel lumen than balloon angioplasty alone. Early data from large observational registry studies published in the early 1990s provided evidence of the safety of the procedure.

    Excimer Laser Commercialization

    In the mid-90's, excimer laser technology was ready for commercialization.

    By 1994, Advanced Interventional Systems (AIS) had commercialized a system and gained FDA approval for the procedure. Later in the decade AIS merged with Spectranetics, Inc., which had developed an excimer for treating peripherals. There are approximately 1,000 Spectranetics lasers placed today, and thousands of excimer laser endovascular procedures are performed each year. The Ra Medical team, which includes members of the Spectranetics and AIS development teams, began developing the DABRA Laser System, including the excimer laser and DABRA Catheter for ablating blockages in 2005.

    Some of the very first patients share what their life was like before getting treated using the DABRA System, and how their life has changed dramatically one year following treatment.

    50-Year-Old Female Patient

    Excel Medical Center, Tijuana, Mexico

    Dr. Ernesto Rodriguera crossed a 10-12cm CTO in the right SFA using the DABRA Laser System. The patient remains patent one year after treatment.

    84-Year-Old Male Patient

    Excel Medical Center, Tijuana, Mexico

    Doctors had performed a femoral popliteal bypass, but it reoccluded and so this patient was referred to Dr. Ernesto Rodriguera, who successfully used the DABRA Laser System. The patient remains patent one year after treatment.

    68-Year-Old Male Patient

    California Heart & Vascular Clinic, El Centro, CA

    A doctor at a large hospital told this man he would never play tennis again. He had been walking with a can for more than a month when he approached Dr. Athar Ansari for a second opinion. Dr. Ansari used the DABRA Laser System to unclog his popliteal artery, and he was back on the tennis court three days later. One week later, Emmy Award-winning journalist Kym McNicholas rallied against him and had him running for the ball.

    Peripheral Artery Disease impacts 1 in 20 Americans over age 50. It's a common and often underdiagnosed disease caused by a narrowing of the blood vessels, mainly in the legs, caused by plaque build-up. If left untreated, PAD can lead to amputation. Symptoms may include: pain/cramping in the legs while walking or at rest; non-healing ulcers/blisters on the lower legs/feet/toes; and gangrene (discoloration of the skin).
