PROMOGRAN PRISMA Matrix is designed to provide protection from infection while encouraging growth of new cells. This is done by addressing the continuous changes in the wound microenvironment. PROMOGRAN's unique combination of 55% collagen, 44% ORC and 1% silver-ORC absorbs destructive components of chronic wound fluid and creates the optimal environment for cellular growth. PROMOGRAN PRISMA jump starts the healing process in stalled wounds. Indicated for use on wounds clear of necrotic tissue, such as: diabetic, pressure, venous ulcers, and traumatic and surgical wounds.
