DuraMatrix-Onlay Plus


DuraMatrix-Onlay PLUS is derived from purified, bovine Achilles tendon. It is intended for use as a dura substitute for the repair of dura mater. In addition to the thick, spongy texture, this fourth-generation DuraMatrix product has a minimally porous, collagen layer. This layer helps produce a lower liquid permeability rate compared to that of DuraGen Plus as shown in a bench test.1,3 DuraMatrix-Onlay PLUS offers a balanced resorption profile that occurs over approximately 8 weeks.2,3
