The dura repair patch, ideal for dural tear treatment, is made from the submucosal layer of porcine small intestine, forming a pale yellow sheet-like object that can degrade and be absorbed in the body.
Feel free to explore our range of biosis products!
The material of the Biosis Healing dural repair patch is a decellularized submucosal matrix from porcine small intestine, produced through a non-crosslinking process that allows for complete degradation and absorption. It has a three-dimensional, loose, porous structure, rich in various bioactive components.
Dural repair products are used for the repair of defects in the dura mater (spinal).

Dura patch materials are critical components in neurosurgery, specifically designed for the repair and reconstruction of the dura mater, the outermost membrane covering the brain and spinal cord. These dural repair patches are used to seal dural tears, prevent cerebrospinal fluid leaks, and promote natural healing.
Modern dura patch materials are typically made from biocompatible substances such as collagen, synthetic polymers, or processed human or animal tissues. Collagen-based patches, for example, are favored for their excellent biocompatibility and ability to integrate seamlessly with the patient’s own tissue. Synthetic options, like those made from polytetrafluoroethylene (PTFE), offer durability and reduced risk of infection.
Dura repair surgery is a specialized procedure aimed at repairing the dura mater, the tough outer membrane that surrounds the brain and spinal cord. Damage to the dura can occur due to trauma, infections, or as a result of surgical procedures, leading to complications such as cerebrospinal fluid (CSF) leaks or infections like meningitis.
The primary goal of dura repair surgery is to close any defects in the membrane to prevent CSF leakage and protect the brain or spinal cord from infection. The procedure may involve suturing the dura, applying a synthetic or biological dural repair patch, or using sealants that encourage tissue healing. In some cases, tissue from the patient's own body, such as fascia, may be used along with a dural repair patch to patch the defect.
Dura repair surgery is commonly performed during neurosurgical procedures, such as tumor removal, spinal surgeries, or traumatic brain injury treatment. The complexity of the surgery depends on the location and size of the defect. In many cases, the use of a dural repair patch ensures a more secure and effective closure. Post-surgery, patients are closely monitored to ensure that the repair is successful, and to prevent complications like infection or recurrent CSF leaks.
