What does REVOLVE™ System do?

REVOLVE™ System from LifeCell, an Acelity Company, is a single use, sterile, disposable device intended for harvesting, filtering, and transferring of the patient’s own fat tissue. It offers surgeons a simple, closed system that controls critical variables in fat grafting. It enables high volume fat processing (up to 700 mL lipoaspirate) in less than 10 minutes, offering the potential to reduce OR procedure time.


How does a surgeon use REVOLVE™ System in a fat grafting procedure for the breast?

Step 1:

Fat Harvesting

Your surgeon will perform liposuction to remove fat from an area of the body where you have excess fat, such as the inner thighs, stomach, buttocks, or lower back. Your surgeon will make small incisions and insert a thin tube or cannula through these incisions. The fat is then suctioned out of your body using a surgical vacuum or syringe. Liposuction is normally performed with intravenous conscious sedation or under general anesthesia.

Step 2:

Wash/Process Fat with REVOLVE™ System

 

Your surgeon will collect the fat tissue in to REVOLVETM System. It will be washed and processed to separate the fatty tissue from fluid waste and contaminants. The entire process is done in a single closed device.

Step 3:

Fat Transfer

After the fat is processed, your surgeon will transfer the fat to a syringe and then inject the fat into the breast. Your surgeon will graft the fat to your breast in order to enhance volume, shape or correct deformities.

What are the potential benefits REVOLVE™ System offers to patients?

A pre-clinical study showed that REVOLVE™ System provided equivalent graft retention to the centrifugation technique and significantly higher retention than the decant method. REVOLVE™ System also removes more free oil and red blood cells from the fat graft than either the decantation or centrifugation methods. These are two techniques commonly used by surgeons to wash and filter fatty tissue in autologous fat grafting procedures.  It is important to know that correlation of these pre-clinical results to results in humans has not been established.1

What are the risks of fat grafting?2

  • Fat cells removed from one body site and injected into another do not always survive.  Multiple fat grafting sessions may be required to achieve your desired volume enhancement. 
  • You will need to have an adequate supply of excess fat for the procedure.  While results may be immediately visible, swelling may take several months to resolve.
  • Fat injected into the breast may be absorbed by the body, may become liquid and form a cyst, may calcify, or may produce scarring.
  • Fat grafting may also produce changes in the breast that may be deemed suspicious during examination by a physician or on mammography, and may lead to further testing to determine if the findings are related to breast cancer.
  • Some common adverse effects associated with autologous fat transfer are asymmetry, over- and/or under-correction of the treatment site, tissue lumps, bleeding and scarring.
  • Autologous fat grafting should not be performed in the presence of any disease process that adversely affects wound healing, and in patients who are in poor overall health.

Are there any types of patients for whom the use of autologous fat transfer is contraindicated?

Autologous fat grafting should not be performed in the presence of any disease process that adversely affects wound healing, and in patients who are in poor overall health.
