This device sounds really interesting, and may be of special interest to nurses who work in long term care where bedsores are an unfortunate common occurrence.

From engadget.com:

Patients suffering from bed sores may find a glimmer of hope in LifeWave’s new non-invasive BST (Bed Sore Treatment) device. It aims to speed healing in stubborn bed sores and similar ulcers by stimulating tissues around the site with a current that mimics the natural electrical activity found in a “normal wound.” The nervous system then recognizes the pulse as a natural signal to promote healing in necrotic tissue. Pilots have already begun in Europe and clinical trials have been scheduled in prelude to official marketing of the Israeli-based startup’s technology in the US.
