DuraMatrix Collagen Dura Substitute Membrane

Collagen Dura Substitute
• Onlay or Sutured Implantation
• Excellent Handling Characteristics
• Strong and Conformable
• Balanced Resorption
• Watertight Material
• Highly Purified Type I Collagen
DuraMatrix represents the next generation in dural
substitute technology.
DuraMatrix is indicated for use as a dural substitute for the repair of dura mater.
Product Overview
DuraMatrix is a conformable and resorbable membrane matrix engineered from
highly purified type I collagen. DuraMatrix is designed with a thickness similar
to that of native dura. DuraMatrix has excellent handling characteristics,
is flexible and conforms to the contour of the defect.
The unique conformability properties of the membrane combined with its
mechanical strength allow DuraMatrix to be applied as either an onlay membrane
or sutured in place. In a large scale animal study1 and clinical study2, DuraMatrix
was shown to facilitate healing with balanced in vivo resorption of the implant
and regeneration of host tissue.

Animal Model
Summary of Animal Duraplasty Model1 (Fig.1)
At 12 weeks, it was observed that there was negligible adhesion of the implants to
the underlying cortex of the brain, and that the dural defects were completely or
almost completely repaired. There was complete or nearly complete incorporation
of DuraMatrix with the native dura at the edges of the defects.
No white blood cells were found in the cerebral spinal fluid at 12 weeks
after implantation.
Under the microscope, at 12 weeks there was approximately 40% of the implant
remaining, which was balanced with the regeneration of new tissue. Evaluation of
gross and microscopic data for sutured and non-sutured DuraMatrix at 2, 7, and
12 weeks showed no significant difference. Under the microscope and in agreement
with gross observations, DuraMatrix exhibited negligible adhesion to the cortex,
but good anchorage to the native dura at the edges of the defects. By 12 weeks, host
fibroblasts had invaded the implants and produced new collagen as DuraMatrix
was resorbed. Neovascularization of the dura substitute was evident.
Inflammatory changes or foreign body responses were minimal.
