ADVANCED BIOMEDICAL CONCEPT
WHAT IS IT
ExaShape is a membrane derived from processing the pericardium from cattle, under 24 months of age, selected and controlled at all stages of growth for feed and the environment in which they grow1.
OUR SECRET IS BILAYER
Designed for Reconstructive Plastic Surgery, the Exashape membrane is processed through a proprietary method that maintains the unique qualities of natural pericardium1.
ExaShape guarantees fast integration times with cell ingrowth2, minimal inflammation3 and negligible serum production, while maintaining remarkable mechanical properties1. The two layers perform a specific task in the integration process.
Fibrous layer: Highly porous, it welcomes cells and, together with the matrix components, allows cytokines and growth factors to trigger the immediate revitalization process and early neoangiogenesis2.
Compact layer: it is quickly repopulated by ﬁbroblasts and VEGF2. After implantation, there is no accumulation of inflammatory or giant cells. It is the part that provides the most solid structural support.
The bilayer membrane undergoes a 3-stage process of revitalization
by endogenous connective tissue:
The cell-friendly preserves the active elements in the repair process within the membrane: proteoglycans, hyaluronic acid, ﬁbronectin, elastin and of course, native collagen. They represent a natural reservoir of bioactive factors, which participate in the revitalization process by controlling inflammation while promoting cell proliferation and migration 2.
We limit the amount of biological mass implanted (up to 50% less, due to the lesser thickness of pericardium compared to dermis) promoting integration, even in cases of poor blood supply, while maintaining the highest bio-mechanical performance1, 4.
