Severn Dural Substitutes

Severn Healthcare Technologies Ltd have a range of dural substitutes which are manufactured by MedPrin Biotech, a company specialising in the development and manufacture of regenerative medicine materials and implantable medical devices.

Forming part of our comprehensive cranial closure range of products, we have two dural patches in the portfolio, allowing the surgeon to choose between a fully synthetic patch and one containing collagen.

ReDura - Synthetic Dural Substitute

medprin1

ReDura™ is a biomimetic, absorbable and 100% synthetic dural substitute. Made of PLLA, a well proven and researched synthetic material, it is designed to promote the rapid repair and regeneration of the dura following open cranial surgery.

ReDura™ has excellent handling characteristics and the structure of the patch closely mimics that of the natural extracellular matrix (ECM), thus providing a favourable environment for dural cell migration, proliferation and growth. During the healing phase, the product provides a watertight barrier, preventing the leakage of cerebrospinal fluid (CSF) and its associated complications. Unlike some other dural substitutes, ReDura™ does not swell.

 Features:

  • Synthetic- no risk of animal infection
  • Balanced repair and regeneration profile
  • Watertight with hydrophobic properties to prevent CSF leakage
  • High Mechanical strength and Anti-adhesion allows for excellent handling in the surgical field
  • Close conformity to patient’s anatomy - similar to native Dura
  • Can be used in Onlay and sutured closure techniques, no need for multiple patches to be kept on the shelf.

NeoDura - Novel Dural Patch

 

medprin2NeoDura™ has a similar composition to ReDura™ but with the addition of 20% collagen for those surgeons who prefer a collagen-based dural substitute.
NeoDura™ shares many of the key features of ReDura™ but with the added advantage of improved conformity to the dura combined with a high mechanical strength. The collagen component means that it also has enhanced resorption characteristics. Like ReDura™, the product also acts as an adhesion barrier between the brain and the skull.

   

Features

  • Balanced repair and regeneration profile with nano
  • Watertight with hydrophobic properties to prevent CSF leakage
  • High Mechanical strength and Anti-adhesion allows for excellent handling in the surgical field
  • With the addition of Gelatin NeoDura has excellent conformity to patients anatomy- similar to native Dura
  • Can be used in Onlay and sutured closure techniques, no need for multiple patches to be kept on the shelf.
