About us

Who we are

Veldana Medical SA is a Swiss company based in Morges, on the shore of the Lake Geneva.

Veldana Medical SA (earlier Wallsten Medical SA) was founded in the 90’s to develop, produce and commercialise a minimally invasive method for the treatment of Heavy Menstrual Bleeding (HMB) – more specifically Dysfunctional Uterine Bleeding – invented by the Swedish Engineer Hans Wallstén. This medical device was named Cavaterm™.

The benefits of the Cavaterm™ system as a safe and easy-to-use method to treat DUB soon convinced physicians all over Europe, then overseas. Their feedback allowed further product developments for an ongoing product evolution based on users’ needs and wishes.

Today Cavaterm™ is recognised as a method of choice for the treatment of DUB by healthcare professionals offering minimally invasive therapies and using the most sofisticated technologies.

What we do

All research and development leading to production follow-up and product updates is performed in our laboratory by qualified and experienced engineers.

Veldana Medical SA owns a clean room and a factory for the production of Cavaterm™ catheters and central units. All products are manufactured, calibrated and controlled on site in Morges.

Product training, information, communication, promotion and distribution is performed by our sales and marketing department. Veldana Medical is represented worldwide by exclusive distributors appointed in different countries or areas.

Our structure also covers customer service, supply chain, logistics, quality assurance, clinical and regulatory affairs, HR, IT, finance and administration services.
