- •Ulcer greater than or equal to 2cm2 and less than or equal to 20cm2 at the time of enrollment.
- •Subject has adequate circulation to the affected extremity, as demonstrated by at least one of the following within the past 30 days:
- •Dorsum transcutaneous oxygen test (TcPO2) with results ≥ 30 mmHg, Or
- •ABIs with results of ≥ 0.7 and ≤ 1.2, Or

- •Patient able to ambulate at home or in the clinic with or without mobility aids.
- •The subject is willing to accept treatment with a porcine based product and to undergo weekly compression wrapping.
- •The subject is medically stable, in the opinion of the investigator.
排除标准
- •Potential subjects meeting any of the following criteria will be excluded from enrollment
- •Index Ulcer Assessment:
- •Penetrates down to muscle, tendon, or bone.
- •Presence of another venous leg ulcer within 2 cm of the index ulcer
- •Index ulcer determined to be due to a condition other than venous insufficiency.
- •Exhibits overt clinical signs and symptoms of infection with cellulitis surrounding the wound margin.
- •Known or suspected local skin malignancy to the index diabetic ulcer.
- •Wound duration > one year without intermittent closure.
- •Prior therapies - Subjects receiving treatment with any of the following will not be eligible for enrollment:
- •In the last 7 days - Negative pressure wound therapy (wound vac or SNaP®) of the index ulcer
- •In the last 7 days - Hyperbaric oxygen (HBO) therapy
- •In the last 30 days - Treatment with cytotoxic chemotherapy, application of topical steroids to the ulcer surface, or use of ≥ 14 days of immune-suppressants (including systemic corticosteroids); or subject is anticipated to require such medications during the course of the study
- •In the last 30 days - study ulcer treatment with any advanced therapy, including, biomedical or topical growth factors, tissue engineered materials (e.g. Apligraf or Dermagraft), sterilized placental allografts (EpiFix, NovaFix, etc.), or other scaffold materials (e.g. OASIS® Wound Matrix, MatriStem Wound Matrix )
- •In the last 8 weeks - Amputation or revascularization (surgical or stenting) to the affected leg
- •Subject criteria that will make subject ineligible for enrollment:
- •Known hypersensitivity to porcine based products.
- •Known osteomyelitis or active cellulitis requiring antimicrobial therapy at wound site.
- •End stage renal disease requiring dialysis.
- •Immune system disorders including Systemic Lupus Erythematosus (SLE), Acquired Immunodeficiency Syndrome (AIDS) or HIV
- •Presence of any condition (including current drug or alcohol abuse, medical or psychiatric condition) that is likely to impair understanding of or compliance with the study protocol in the judgment of the Investigator.

- •Subjects currently enrolled in this study. Concurrent enrollment in the study is prohibited.
- •Subjects currently receiving radiation therapy or chemotherapy.
- •Any pathology that would limit the blood supply and compromise healing or non-revascularizable surgical sites
