CRITICAL RED FLAG: Renephra Ltd was dissolved in August 2023 and no longer exists as a legal entity. The submission relies on obsolete data from a 2018 investment campaign. Additionally, the claim that "most people have used my product" is demonstrably false for a specialized medical device with limited clinical trial success (NCT03959930). The project is inactive and the technology failed to reach commercial viability.

This is a substantial patient group with unmet clinical needs and is an estimated £3billion market worldwide. - Chronic Oedema is a debilitating and underestimated health problem affecting millions of people, leading to very poor quality of life, complications, frequent hospital admission and high costs of care. Currently patients' only alternative is physiotherapy, compression bandages or surgical treatment until Renephra finalizes its wearable, unobtrusive and easy-to-use device for controlled fluid removal from the skin. - Fluid overload is a major and growing problem, for example a major proportion of the 3 million renal failure patients and 26 million with heart failure suffer from fluid overload. Underlined by increasing prevalence of both diseases (8% annually), this is unsustainable and new approaches are needed urgently. Current solutions to this problem are limited. When diuretics fail, which occurs in up to 30% cases – the only other option is dialysis or ultrafiltration. These severe treatment strategies are not suitable for everyone, is debilitating and costly. The Renephra patented Fluid Removal Device uses micro-needle technology combined with negative pressure therapy to access and remove excess interstitial fluid from the skin.
