Duraheal (Duraersatz)

Duraheal is a porcine pericardium-derived, cell-free, non-pyrogenic, transparent collagen matrix

Properties

• native, transparent collagen matrix for inspection of the subdural situation
• supports adhesion and proliferation of regenerative cells
• biocompatible
• liquid-tight
• tear-resistant
• can be used flexibly on or under the dura mater
• fixable by sewing or gluing
• fully-resorbable
• vollständig resorbierend

Fields of application

Duraheal is intended for use as a surgical collagen membrane (“patch”) for neurosurgery for the liquor-tight covering of defects of the dura mater. The compact arrangement of collagen fibrils forms a closed surface of the membrane, which prevents the passage of cerebrospinal fluid and at the same time offers a guide rail for the regeneration of the dura. Thus, post-operative leakage of CSF through the membrane is prevented and the basis for regeneration of endogenous dura is created. Duraheal can replace the dura-plasty with autologous tissue and thus saves valuable operating time on the one hand and removal-related wound pain for the patient on the other.

Duraheal is a highly pure collagen matrix and is offered without additives or preservatives, which contributes to Duraheal’s high tissue tolerance.

Practical application description (implantation)

• After opening the inner sterile pack, use sterile, atraumatic forceps to grasp Duraheal at the edge and remove using aseptic technique.
• The size of the Duraheal patch can be adjusted during surgery at the surgeon’s discretion.
• Duraheal must be rehydrated in sterile isotonic saline solution for at least 5 minutes.
• Visually check both sides and, if recognisable, implant the apparently smoother side facing the nerve tissue.
• The low thickness of the film-like patch allows it to be used in the overlay technique.
• Duraheal can be attached to the edge of the patient´s tissue by suture, clamp, stapling or fibrin glue.
• For implantation with suture, the suture must be placed 2-3 mm from the edge of the implant.
