Exceptional handling predictability and conformability

Cortiva® 1mm Perforated Tailored and Cortiva® 1mm Perforated allograft dermis grafts feature a consistent, precision-engineered perforation pattern of 5mm hexagonal openings, enabling multidirectional expansion for exceptional drape, flexibility, and conformability to contoured and complex surfaces.1,2,3,4,*,† This open geometry was shown to support effective fluid exchange while delivering predictable handling in a wide range of surgical applications.1

While both grafts share this advanced perforated pattern, Cortiva® 1mm Perforated allograft dermis includes a basement membrane. In contrast, Cortiva® 1mm Perforated Tailored is basement membrane-free, offering a fully orientation-independent graft that allows for integration and enhanced versatility in dynamic surgical settings.

Fluid transfer efficiency demonstrated in Franz cell testing

A modified Franz cell test measured how long it took for 500mL of fluid to pass through 6-by-6-centimeter samples of three dermal allografts: Cortiva® 1mm Perforated allograft dermis, FlexHD Pliable Perforated, Thin, and AlloDerm RTM Perforated. Cortiva® 1mm Perforated allograft dermis demonstrated drainage rates three to six times faster than the others.¹,‡

Uniform intra-graft predictability

Predictability is our focus. Cortiva® allograft dermis grafts are precisely controlled to ± 0.1mm, measured every 2cm increment.1

Combines a preshaped graft design with hexagonal perforations to provide ease of use and versatility across dynamic, patient-centric procedures.11
