T2016-248 An electrically conductive dressing that improves wound healing outcomes by inhibiting biofilm growth and neutralizing bacteria

The Need

Wound healing and disinfection represent significant hurdles within the medical industry with current standards for treatment falling short leaving patient safety compromised. After the formation of an open wound, adequate cleaning and dressing is paramount to preventing infection. However, it is common for collections of microorganisms, especially bacteria, to form biofilms, even after a wound is bandaged/dressed. These films allow bacteria to become 10 to 1,000 times more resistant to antibiotic medications compared to non-film bacteria. Additionally, a study from the National Institutes of Health (NIH) indicated that bacterial biofilms accounted for over 2 million cases of infections reported in the U.S., leading to $5 billion in added medical costs annually. While existing wound dressing solutions are able to suppress bleeding and protect against severe contamination, none are able to fully prevent the formation of bacterial biofilms. This capability gap has led to increased demand among medical providers for solutions able to neutralize bacterial biofilm formation, which would lead to more sterile wounds and better infection prevention.

The Technology

Dr. Shaurya Prakash and colleagues at The Ohio State University have developed electroceutical dressings that use direct current to prevent biofilm formation and neutralize bacteria. The technology features a dressing comprised of an antimicrobial polyester fabric and uses a flexible, lightweight circuit with a pair of electrodes that are used to apply electrical current to the treatment area. The circuit is protected by elastic adhesives and padding, with power delivery coming from a battery pack encased in padding for fluid protection.
