Tissue and Cells Regeneration Method Estar Medical Ltd. is a privately held medical-device company operating in the Biologics/Regenerative Medicine arena, being the inventor of the proprietary unique technology of the "Tropocells™ PRP System" ("Tropocells") - an advanced innovative Platelet Rich Plasma ("PRP") preparation system to obtain pure PRP. PRP is a fraction of autologous plasma with supraphysiological concentration of platelets. Platelets contain α granules, which comprise cytokines, growth factors and bioactive proteins essential for tissue repair and healing. Upon injury, platelets initiate blood coagulation and release growth factors that activate the healing response (PDGF/ TGF/ VEGF/ EGF etc.). These bioactive proteins initiate connective tissue healing; bone, tendon, cartilage and ligament regeneration and repair, promote development of new blood vessels and stimulate the wound healing process. The Tropocells PRP is a revolutionary repair system that uses the body’s own growth factors in the exact location where the patient wants the skin/wound to repair and rejuvenate itself. Among the key advantages of the Tropocells System: • Only 10 minutes centrifugation at 1500G to obtain pure PRP with its growth factors without Red Blood Cells and Granulocytes; • Expensive capital equipment is not required - simple low cost fix or swing centrifuge perfectly works with Tropocells; • The simple preparation process takes no more than 10-15 minutes from blood collection to PRP harvesting. The process ensures optimum concentration of platelets and their growth factors at a rate of 4-5 folds above base line; • The flexible and easy to use system enables the users to obtain higher/lower concentration by simply adjusting the amount of clear plasma removed from the tube • Patented gel separator for efficiency ensures clear PRP; • Activation and clot formation can be achieved for dental and wound healing; • The Tropocells is US patented, FDA cleared (510K for orthopedic applications) and CE certified (Class IIb). Estar Meidcal has an advanced products portfolio for a variety of designated applications, such as: aesthetic/dermatology, orthopedics & sports medicine, wound care, dentistry, veterinary, ophthalmology and others.
