SERI® Surgical Scaffold is a knitted scaffold composed of ultra pure, silk-derived fibroin2 sourced from the Bombyx mori silkworm. As such, SERI® Surgical Scaffold is not derived from human cadaver or animal tissue.
Raw silk protein filaments are twisted into a multifilament fiber2
Raw silk protein filaments are combined by helical twisting to form a multifilament protein fiber.2 These raw silk fibers are composed of fibroin protein core filaments that are naturally coated with the globular protein sericin.3
Sericin is extracted from the fiber, leaving behind fibroin protein with minimal residual sericin1,4
The purified bioengineering process removes the sericin, leaving behind fibroin protein filament of ≥ 95% purity on average.1,3,4
Fibers are knitted into a patterned scaffold2
Purified fibers are then assembled into a 3-dimensional patterned scaffold, with pores that are at least 10,000 µm2.1,2 The resulting scaffold is mechanically strong, flexible, and tear resistant.1,2 Plus, SERI® Surgical Scaffold can be easily cut with surgical scissors and will not unravel or fray.1,2
