Venous Ulcers

Ultrasound Band-Aid Heals Venous Ulcers
A small clinical study showed promise for a new method of treating chronic wounds; an ultrasound applicator that can be worn like a band-aid. 

The applicator delivers low-frequency, low-intensity ultrasound directly to wounds, and was found to significantly accelerate healing in five patients with venous ulcers, which are caused when valves in the veins malfunction, causing blood to pool in the leg instead of returning to the heart. This pooling, called venous stasis, can cause proteins and cells in the vein to leak into the surrounding tissue leading to inflammation and formation of an ulcer. /.../
