Brief Summary:

The purpose of this study is to determine:

  1. If vacuum assisted closure (VAC®) therapy results in altered proteomic expression of angiogenic markers compared to moist wound therapy.
  2. If VAC® therapy results in increased angiogenesis compared to moist wound therapy.

Primary Outcome Measures :
  1. Altered proteomic expression evaluated by angiogenic markers using biomolecular assays of biopsy samples at Day 0, Day 3, Day 7, Day 21, and Day 28

Secondary Outcome Measures :
  1. Increased angiogenesis of the lower extremity wound will be quantified using the MicroScan™ (video microscope) at Day 0, Day 3, Day 7, Day 21, Day 28, Day 42, and at follow up visit.

Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patient is male or female and > 18 years old.
  • Patient or patient's legal authorized representative is willing to sign informed consent.
  • Patient has a post surgical dehisced wound of the lower extremity for longer than two weeks and less than one month.
  • Patient has transcutaneous oximetry (TcPO2) evaluation that demonstrated tissue hypoxia in the periwound region, as indicated by a reading of 10-40 mmHg within the prior two weeks.
  • Ankle Brachial Index > 0.7 within the prior two weeks.
  • Patient is not pregnant (pregnancy test is negative) and non-lactating at Visit 1.
  • Patient does not plan on becoming pregnant during the course of the study.
  • Patient is willing to use effective method of contraception for the duration of the study, is permanently sterilized, or post-menopausal as defined by cessation of menses for at least one year prior to enrollment in study.

Exclusion Criteria:

  • Diagnosed and untreated wound infection.
  • Poor nutrition status as evidenced by pre-albumin < 12mg/dl within the past 30 days or extracellular mass < 95%.
  • Presence of sickle cell disease.
  • Presence of connective tissue disease (e.g. history of or active lupus).
  • Hemoglobin A1c (HbA1c) levels greater than 9% thirty days prior to screening visit (if patient is confirmed diabetic).
  • Treatment with an investigational therapy within the previous 30 days.
  • Lower extremity wound (under consideration for study) with malignancy.
  • Lower extremity wound (under consideration for study) with untreatable cellulitis.
  • Presence of untreated osteomyelitis.
  • Presence of any systemic hematologic disorder or condition that would impede healing.
  • History of radiation to the wound area.
  • History of drugs that may delay wound healing.
  • History of thermal injury to the wound area.
  • Prior VAC® therapy to the wound within 30 days of enrollment.
  • Current or prior treatment with hyperbaric oxygen therapy (HBO) or warm-up therapy to the same wound.
  • Recent diagnosis of cancer or active management of cancer within the last year.
  • Treatment with skin or dermal substitutes or dressings with living cells capable of producing growth factors within the previous 30 days.
  • End stage renal disease.
  • History of alcohol or drug abuse that may impact protocol compliance or delay wound healing.
  • Known hypersensitivity to hydrogel or any disposable component of the VAC® Therapy System.
  • Necrotic tissue with eschar present which cannot be debrided.
  • Any other severe concurrent disease, which, in the judgment of the investigator, would make the patient inappropriate for entry into the study.
