An Arizona medical device manufacturer, Silverleaf Medical Products, applied to the FDA this week to expand the use of its electronic antimicrobial wound dressing. The firm makes what are like electronic band-aids that prevent bacterial and microbial penetration; the material is activated by the wetness of the wound.

Silverleaf’s product page says: “PROSIT activates and generates a voltage at the surface when moistened. When active, PROSIT prevents microbial penetration. Present device can be left on for 3 days.”

The FDA approved use of the electronic dressings in 2006.

From the company’s Web site:
