GPS™ System

The Gravitational Platelet Separation System (GPS™ System) takes platelet concentrate systems to a new level. From a small volume of patient blood, the GPS™ will consistently provide the highest quality platelet concentrate versus any other point-of-care system. The GPS™ offers many advantages to the patient, nursing staff and surgeon.

What is Platelet Concentrate?

Platelet concentrate produced by the GPS™ System is a platelet rich gel that is derived from the patient's own blood. Platelet concentrate is then reintroduced to the wound to speed the body's natural healing response.

 

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

 



The Secret is the Floating Buoy

 

Unlike systems that cannot compensate for the difference in red cell counts from one patient to the next, the GPS™ System adapts to the plasma/red cell interface with a floating buoy.

 

The proprietary, finely tuned buoy mechanism is engineered to separate the plasma/red cell interface by reacting to the density of each layer. Under centrifugal forces, the buoy will "float" within the tube to the optimum interface point of the red cell/"buffy coat" layer. The optimum interface point is found regardless of the hematocrit of the patient, ensuring a consistently high platelet count for each spin.

 

Usage of the platelet concentrate

 

The platelet concentrate or platelet rich plasma (PRP)can then be used in combination with our bone substitutes like Calcibon® Granules or Collapat® II. Adding the osteoinductive potential to the osteoconductive Matrix of our bone substitutes will then speed up the mineralization process and also improves the density of trabecular bone. This may be very beneficial when it is used as a filler material for cages.

 

 

Possible indications are:

 

  • Bone defects
  • Pseudoarthrosis
  • Non-unions 
  • Vertebral fusions
  • Revision surgery, especially in hip revisions for the acetabulum
  • Tendon ruptures (e.g. Achilles tendon)
  • Chronic wounds (e.g. diabetic ulcers)
