Pre-hydrated Block Graft

Aqueous Solution Preservation (ASP)

Exclusive ASP technology combines an isotonic calcium chloride preservation media with a state of the art PETE trays system to provide allografts immediately ready for implantation. The technology allows allografts to be stored in a fully hydrated state at ambient temperature eliminating the need for lengthy graft preparation.

  • Retains the native biomechanical strength of the allograft
  • Preserves the natural biological structure of the tissue by preventing calcium leaching into the storage media
  • Eliminates microcracks that can be formed during freeze-drying processes
  • Provides a biologically favorable environment for tissue remodeling
  • Validated for a five-year shelf life

Biomechanical testing revealed cervical allografts preserved in ASP display equivalent mechanical strength to frozen grafts and superior mechanical strength to lyophilized grafts.
