Medical device for automatic preparation of high quality foam for sclerotherapy of varicose veins
Approximately 25% of adults have varicose veins, with prevalence increasing to over 80% if spider veins are also considered. The rising geriatric population is further accelerating these figures, as one in two people over the age of 50 are affected by varicose veins. In recent years, due to the possibility of infection and other adverse effects during invasive surgeries, traditional surgical treatment (surgical ligation and stripping) has given way to minimally invasive procedures, which also reduce hospital stays and costs. Consequently, a growing number of doctors are adopting foam sclerotherapy, endovenous laser treatment, and radiofrequency ablation over conventional surgical practices. Within these new treatment approaches, foam sclerotherapy is the preferred approach given its favourable efficacy and safety profile coupled with simplicity and relatively low cost. Foam sclerotherapy involves transforming a chemical sclerosing agent into foam and injecting it into the affected vein. The sclerosant foam irritates the lining of the blood vessel, causing it to collapse and stick together. Current manual foam preparation method broadly utilized by doctors (Tessari’s method) presents substantial limitations in terms of quality, consistency, versatility, and safety. VARIXIO Sclerotherapy Microfoam System being developed by VB Devices addresses these limitations by automating, standardizing, and greatly simplifying foam preparation. VARIXIO adds versatility and safety to this obsolote treatment method. Having secured patent protection for the device and validated the concept at the prototype level, the company is seeking
funding to pursue industrial, regulatory, and commercial feasibility of the VARIXIO device.
