I started using the Puregraft® bag about 2 years ago and it has finally been approved for use in my local NHS hospital. And what a difference it makes. It is a closed system, so processing the fat is sterile, less messy and quicker. Due to its filter, the fat appears to be cleaner with less blood. And anecdotally, my observation has been that survival rates of harvested fat with Puregraft® are higher. A recent study, now confirms this: Long-term volumetric retention of autologous fat grafting processed with closed membrane filtration. Gerth DJ, et al. Aesthet Surg J. 2014 Sep;34(7):985-94.
Another useful tool to improve outcomes for patients!
