Who We Are

Advanced Excimer Laser-Based Vascular and Dermatological Therapies

Ra Medical Systems’ advanced excimer laser systems are tools for use in the treatment of vascular and dermatological diseases. We believe our products enhance patients’ quality of life by restoring blood-flow in arteries and clearing chronic skin conditions.

We currently manufacture and market two lines of products:

DABRA is our minimally-invasive excimer laser and disposable catheter system that is used by physicians as a tool in the endovascular treatment of vascular blockages resulting from lower extremity vascular disease, a form of peripheral artery disease, or PAD, both above- and below-the-knee. DABRA breaks down plaque to its fundamental chemistry, such as proteins, lipids, and other chemical compounds, eliminating blockages by essentially dissolving them.

DABRA has been cleared by the FDA for crossing chronic total occlusions in patients with symptomatic infrainguinal lower extremity vascular disease and has an intended use for ablating a channel in occlusive peripheral vascular disease.

Pharos Excimer Laser is a powerful 308 nm ultraviolet-B excimer laser used by physicians as a tool to treat chronic skin diseases, including psoriasis, vitiligo, atopic dermatitis, and leukoderma. Pharos has FDA clearance to market Pharos in the U.S. for those skin conditions and CE mark clearance for use in the treatment of those skin conditions, as well as market clearance in China, Saudi Arabia and Thailand.

When it comes to total occlusion, normally if you can’t cross with a guidewire, you can’t do it. With DABRA, we were able to stay within the true lumen and recanalize without a wire in front.

It’s very easy, very simple, very trackable, and I did not encounter any problems in the technique. It is really simple and very safe.

One of my favorite treatments for localized psoriasis plaques is the targeted excimer laser.

The Pharos is the only treatment that has ever worked for my scalp. I've tried injections, creams, shampoos, oral medications, and none of it worked. But, since I started the laser treatments, my scalp has cleared more than 85%. There is no pain or side-effects.

Marilyn R.

I've had moderate psoriasis since I was a child. My doctor told me he could help me achieve remission with the Pharos excimer laser. I was skeptical, but now, for the first time in 10 years, I can wear short-sleeves and a bathing suit. I am experiencing remission for the first time in my life.

I've been an excimer laser patient for a few years. Recently my physician switched from offering the other excimer laser to the Pharos laser and I am experiencing even better results.  My Pharos treatments not only provide quicker results but also an overall improvement in my condition.
I now have the ability to use the Pharos laser in many more areas of concern.  With the other laser, I could only treat my scalp because my skin would darken if it was used on any exposed skin. With the Pharos, because it is specifically targets at the problem area, I am able to treat many more areas and not have an unsightly darkening of my skin.  And while the other laser was warm and at times, even hot while receiving treatment, the Pharos does not transmit any heat during treatment.

It works extremely well and is a money maker for my practice.  It’s the best laser I have.

I think it’s important to stay on top of new technology and having the excimer laser as part of our armamentarium against psoriasis has brought us many patients who are seeking a clinic that is state of the art, who has the latest treatments and new treatments for psoriasis and other diseases.

The Pharos excimer laser is an excellent quality laser. Pharos provides excellent service. The patients are routinely very happy with this equipment and so am I. I recommend it wholeheartedly.

Patients who are excellent candidates for the excimer laser are patients with more localized plaque psoriasis of elbows, knees, buttocks, or as an add-on adjunctive therapy after full body NB UVB exposure in our phototherapy box. The excimer laser is very efficient in clearing flexural crease psoriasis, as well as resistant psoriasis of the scalp and genital areas. We often use it in combination with an optimized topical regimen such as steroids and vitamin D3 foams.

I have been using Pharos lasers for over 13 years to treat vitiligo. In fact, I have 3 Pharos. Treatment is painless, quick, and can transform patients’ lives as they see improvement.

The UCI dermatology vitiligo clinic uses Pharos Excimer Lasers. These are our workhorses for vitiligo. We have two Pharos lasers and they are heavily in use five days a week.

The excimer laser is a very important part of the treatment armamentarium for vitiligo. The combination of pigment stimulation and safe local immunosuppression gives rates of success of up to 70%. There is hope for vitiligo.
