The Challenge

Access and delivery of wound care are both significant problems that challenge patients suffering from chronic wounds. In the United States, chronic ulcers are conservatively estimated to cost the health care system $28 billion each year as a primary diagnosis and up to $31.7 billion as a secondary diagnosis. There is also a profound psychological impact on the patients suffering from chronic wounds, such as loneliness, separation from active social life, and depression.

Innovation Details

Aurase® is a hydrogel used in wound debridement to help remove dead or diseased tissue. It contains an enzyme isolated and cloned from medical maggots. Maggots feed on dead and dying tissue and are known to secrete enzymes that allow them to digest the wound debris, leaving behind a healthy wound for healing. Using maggots to clean chronic wounds in a hospital is a challenge because sterile rearing, shipment, and application require highly trained personnel and complex infrastructure. As a gel-based product, Aurase can quickly and easily be applied to infected wounds to activate the body’s own wound cleansing processes. Aurase causes no irritation or damage to healthy tissue, and reduces the time to full debridement without delaying wound healing.
