For many years, cosmetic-plastic surgeons have recognized the value of low pressure
lipoaspiration for successful transplantation of adipose tissue for structural augmentation. In the
introductory years (1980-1990) of liposuction techniques, autologous fat grafting (AFG) was
considered unpredictable. Once bioengineers discovered the mechanisms by which
lipoaspiration worked, the closed syringe system for gentle harvesting and transplantation was
developed and patented. Early belief that effective lipoaspiration was directly related to force of
vacuum was replaced by understanding, that, introduction of fluid into the fat layers permitted
the fat cells and stroma to enter into a suspension. This suspension was easily extracted through
use of closed syringes, and provided adipose tissues with reduced damage and improved grafting
results...
