Stromal Vascular Fraction From Lipoaspirate to Treatment of Chronic Non-healing Wound

This is a Phase I, open-label, single arm study to demonstrate the safety of Antria Cell
Preparation Process during fat grafting augmented with autologous adipose derived stromal
vascular fraction to demonstrate the safety and efficacy of administration of SVF enriched
fat grafting in chronic wounds.

Inclusion Criteria:

4. Subjects with a known drug or alcohol dependence within the past 12 months as judged
by the Investigator

5. Any other disease condition or laboratory results that in the opinion of the
investigator may be clinically significant and render the subject inappropriate for
the study procedure(s), may alter the accuracy of study results, or increase the risk
for subjects.
