The V.A.C.Ulta™ Negative Wound Pressure Therapy System is an integrated wound management system that delivers proven V.A.C.® Negative Pressure Wound Therapy and V.A.C. VeraFlo™ Instillation Therapy, which consists of V.A.C.® Therapy coupled with automated, controlled delivery and removal of topical wound solutions. V.A.C.® Therapy, in the absence of instillation, is intended to create an environment that promotes wound healing by secondary or tertiary (delayed primary) intention by preparing the wound bed for closure, reducing edema, promoting granulation tissue formation and perfusion, and by removing exudate and infectious material.
