V.A.C. Therapy System Fact Sheet


KCI's proprietary V.A.C.® Therapy System has revolutionized the way in which caregivers treat the most serious, complex wounds. V.A.C. Therapy utilizes an open-cell polymer foam dressing that is conformed to the wound bed. When sealed and placed under negative (vacuum) pressure, the system creates a unique wound healing environment that has been shown to promote the wound healing process, reduce edema, prepare the wound bed for closure, promote the formation of granulation tissue and remove infectious materials.

In 1996, KCI introduced this innovative approach to the treatment of serious, complex wounds through the use of sub-atmospheric or negative pressure. Known today as “negative pressure wound therapy” (NPWT), KCI’s proprietary Vacuum Assisted Closure®, or V.A.C.® Therapy System has revolutionized the advanced wound care market and remains the most clinically proven alternative for the treatment of complex, hard-to-heal wounds.

Research and Development (R&D)

KCI continues to invest in innovation with an ongoing commitment to research and development aimed at improving patient outcomes while reducing the overall cost of care. In 2008, KCI invested more than $76 million in its R&D efforts, which are led by approximately 240 clinical research and development professionals.

Clinical Distinction

V.A.C.® Therapy is recognized as a significant, clinically proven advancement in wound care that promotes active wound healing at the cellular level utilizing three vital V.A.C. Therapy components:

  • The proprietary V.A.C.® GranuFoam Dressing means the difference between healing and simply draining a wound. GranuFoam Dressings provide increased metabolic activity and evenly distributes vacuum pressure at the wound surface, creating the angiogenesis and cell proliferation necessary for wound healing. Gauze-based negative pressure wound therapy devices only drain the wound. The technology of GranuFoam Dressings also allows the dressing to adapt to the contours of deep or unevenly shaped wounds.
  • The technology of SensaT.R.A.C. Dressings regulates pressure at the wound site to ensure patients receive the prescribed amount of negative pressure for optimal healing.
  • The V.A.C.® Therapy unit utilizes sophisticated software algorithms to provide intermittent and continuous negative pressure to the wound.
