Chronic leg ulcers are painful, debilitating wounds that place a significant burden on the patient, their family, and healthcare resources. Treating leg ulcers can present a significant challenge to clinicians, who currently have a limited range of treatments at their disposal. The mainstay of treatment is compression bandaging, ambulation and elevation at rest. In patients with mobility deficits, or in those who are unable to tolerate compression bandaging, ulcers may deteriorate and never heal. Accordingly, there is a need for novel, alternative devices or strategies that can be used to complement or replace compression therapy.
