This technology uses a centrifuge to separate out the patients own blood components by their various densities. The red blood cells (RBCs) are denser and will move to the bottom. The plasma fraction is the least dense and will float on the top layer. The “buffy coat” which contains the majority of platelets will be sandwiched between the plasma and above the RBCs.

Platelets contain various growth factors (also called cytokines). Platelet-derived growth factor (PDGF), transforming growth factor-beta (TGF-B), insulin like growth factor (IGF), and vascular endothelial growth factor (VEGF) are several that are contained within the platelets.

Platelet concentrate is obtained by the process of spinning down the patient’s own blood and collecting the buffy coat which contains the concentrated platelets and white blood cells. 

Why Platelets?

Platelets contain various growth factors that when applied to a wound site will accelerate the healing response. Platelet-derived growth factor (PDGF), transforming growth factor-beta (TGF-ß)and vascular endothelial growth factor (VEGF) are just some of the growth factors that are contained within the platelets.

Patient advantages

• Patien's own blood is used
• Only a small volume of blood required which is not physiologically significant (55-110 ml)
• The blood is taken in the OR.

Nursing staff advantages

Disposable kit contains all components needed to process one or two collection tubes. No searching for individual items is needed. The single spin system saves time and is the user-friendliest system available. No intra-operative delays. No advanced training needed due to simplicity.

Surgeon Advantages:

• High level of platelet recovery
• Consistency of concentrate 
• Ease of application with spray kit
• May increase incorporation of bone graft
• May optimize environment for soft and hard tissue healing
• Analogous tissue graft
• Cost effective
