Treating varicose veins without surgery

SONOVEIN® is the first robotic solution for a 100% non-invasive echotherapy treatment of varicose veins. It doesn‘t need any additional accessories such as guide wires, puncture kits or catheters and leaves no scars. SONOVEIN can be operated by a single person in a non-sterile environment. No wake-up rooms or hospital beds are required as patients can resume their normal daily activities immediately after treatment.

How echotherapy works

From a histological perspective, vein ablation by echotherapy with SONOVEIN and radiofrequency display identical features – with the significant benefit of echotherapy being completely non-invasive.

The high-intensity ultrasound beam (HIFU) is focused on the vein and a standard ultrasound beam controls the accuracy. As the thermal energy is delivered, the vein shrinks and is sealed closed, similar to other endothermal methods – but non-invasively.

Scientific & clinical expert quotes
prof whiteley

Echotherapy is a medical breakthrough which allows us for the first time in history to treat the patient from the outside. This completely changes the patient experience and eradicates the risks related to invasive surgery or laser treatments.

Professor Mark Whiteley, MS FRCS(GEN) FCPHLEB, consultant venous surgeon and consultant phlebologist, founder of the Whiteley Clinic, UK
Dr obermeyer

It is fascinating to see how SONOVEIN can apply thermal energy to an
insufficient vein completely noninvasively – without catheter, injection
needle or any kind of incision. This opens up possibilities which where unthinkable until now.

Dr. Alfred Obermayer, surgeon at St. Joseph's Hospital, Vienna and head of the Institute for Functional Phlebosurgery, Melk, Austria

It was literally a real walk-in walk-out treatment experience.

Dr. Omar Abu-Bakr, Echotherapy patient & Specialist Venous Surgeon at The Whiteley Clinic, UK

Echotherapy with SONOVEIN will be an absolute game changer in varicose vein treatments – treat venous insufficiency 100% non-invasively is a huge opportunity for physicians without the need for an operating theatre.

For patients this will be a disruptive therapy, providing the safest possible treatment even for high risk patients.
