Practice efficient medicine with VERAFLO™ Therapy.


  • More than 90 percent of chronic wounds contain bacteria and fungi living within a biofilm construct.1

    VERAFLO™ Therapy allows you to cleanse the wound and promote granulation tissue formation at the same time. Traditional V.A.C. Therapy® doesn’t have the ability to cleanse the wound.

    Note: V.A.C. VERAFLO™ Therapy is not a treatment for infection or biofilm

    An independent, retrospective single center study conducted at MedStar Georgetown University Hospital under controlled clinical conditions evaluated the impact of VERAFLO™ Therapy with PROTOSAN® Wound Irrigation Solution (PHMB/ Betaine) initiated at initial debridement compared to V.A.C.® Therapy.
