What is Resorbable Collagen Dural Grafts?
In neurosurgical procedures, it is not sufficient to simply close the operated area, the goal is also to restore that area to its natural pre-surgical structure. Although autografts containing the patient’s own tissue are suitable for this purpose, they are not functional because they require additional surgical incisions and cause time loss. These grafts not only create a temporary barrier but also undergo a biological identity change by transforming into the patient’s own tissue. Instead of trying to mimic nature, Desu Medical provides surgeons with a safe, fast, and permanent repair option by utilizing nature’s own elements.
Unlike synthetic materials, the use of resorbable collagen dural grafts is completely removed from the concept of placing a foreign substance in the body. The material used is Type 1 collagen, the fundamental building block of mammalian tissue. Processed in Desu laboratories to remove antigenic components, this collagen is transformed into a pure scaffold. When the surgeon places this skeleton on top of the dura mater, the body perceives it not as a threat but as an opportunity for repair.
The Reshaping Mechanism of the Resorbable Collagen Dural Graft
The effectiveness of this technology is based on the delicate timing balance between biological degradation and tissue regeneration. The graft begins to be broken down by the body via enzymes as soon as it is placed. However, while this process is taking place, fibroblasts migrate into the graft and begin producing new collagen. The resorbable collagen dural graft acts as a template that guides the fibroblasts.
Desu Medical’s expertise in the manufacturing process is crucial here. If the graft dissolves too quickly, cerebrospinal fluid leaks may occur because new tissue has not yet formed. If it dissolves too slowly, the body encapsulates the graft and fibrosis, scar tissue formation begins.
The resorbable collagen dural graft developed by Desu has a dissolution profile that matches the healing speed of human dura mater. Within approximately 3-6 months, the graft completely disappears, replaced by the patient’s own living, vascularized, and impermeable dura tissue. This process is called creeping substitution and is the ultimate goal of regenerative medicine.
Usage Characteristics of the Resorbable Collagen Dural Graft
For a neurosurgeon, the feel and ease of use of the graft are as important as its biological qualities. Using a patch that is stiff or tends to disintegrate when wet can complicate the surgical process. The resorbable collagen dural graft has excellent coverability. When dry, it can be easily cut and shaped; when wet, it becomes a soft, firm tissue that does not exhibit gelatinous properties.
Desu collagen grafts fit perfectly to the surface of the brain folds. Thanks to surface tension, they adhere tightly to the dura edges. This feature prevents the graft from slipping in deep and narrow working areas. The surgeon does not have to worry about tearing the graft when holding it with forceps. The resorbable collagen dural graft holds the needle when suturing is desired, but often provides a secure closure without sutures.
Safety Profile and Purity of the Resorbable Collagen Dural Graft
The biggest concern with biologically derived products is the possibility of immunological reactions and disease transmission. Desu uses bovine achilles tendon as the raw material source to reduce these risks. This area is the purest and strongest collagen source, free from the risk of spongiform encephalopathy. However, raw material selection alone is not sufficient.
Proprietary chemical and enzymatic methods applied during production remove the telopeptide ends of the collagen (the parts that can cause allergies). As a result, only the non-antigenic, pure collagen structure remains. Thus, the resorbable collagen dural graft does not cause inflammation or granuloma formation in the patient.
Desu Medical’s viral inactivation protocols ensure complete sterility without compromising the molecular structure of the material. The result is a repair material that is safe for surgeons to use and has proven biocompatibility.
Resorbable Collagen Dural Graft for Leak-Free Closure Without Sutures
Traditional dura repair required numerous sutures to achieve leak-proof closure. This not only wastes time but also turns each suture site into a potential leak point. Resorbable collagen dural graft technology enables the “onlay” method. The graft is placed over the defect, extending 1 cm beyond the edges. When it comes into contact with cerebrospinal fluid and blood, the collagen fibers swell, providing a mechanical lock with the underlying tissue. The microporous structure of Desu Medical’s patches increases this bonding strength.
As long as the intracranial pressure remains at normal levels, the graft stays in place and provides immediate leakproofing. Sutureless use can reduce surgery time by 15-30 minutes. This is a significant advantage for a patient under anesthesia. Of course, if the surgeon prefers, the Resorbable Collagen Dural Graft can also be secured with sutures the material’s high tensile strength makes this possible.
Desu Medical’s Engineering on Resorbable Collagen Dural Graft
The difference between a regular collagen sponge and an advanced dural graft is the cross-linking technology used in the production stage. Natural collagen dissolves quite quickly in the body. Desu optimizes the material’s durability and dissolution time by cross-linking collagen fibers. However, this cross linking process is achieved through thermal or physical means, without the use of toxic chemicals.
This engineering approach enhances the mechanical resistance of the resorbable collagen dural graft product while maintaining its biocompatibility. The graft possesses flexibility that will increase its resistance to brain edema or pressure increases that may occur during the post-operative process. It also exhibits anti-adhesive properties, preventing unwanted adhesions between the dura mater and the cerebral cortex. This is an important detail that facilitates the surgeon’s work in the event of a possible second surgery in the future.
Clinical Versatility
The resorbable collagen dural graft can be used in almost every field of neurosurgery:
- Cranial Surgery: Standard closure after trauma, tumor removal, or aneurysm surgery.
- Spinal Surgery: Repair of dura tears after laminectomy or prevention of epidural fibrosis.
- Pediatric Neurosurgery: Safe use in pediatric patients due to its ability to adapt to the growing skull.Skull Base Surgery: Ensures leak-proofing in hard-to-reach and narrow spaces.
Desu Medical offers graft alternatives in various sizes (for instance from 2.5×2.5 cm to 10×12 cm) for different surgical needs. The surgeon can easily cut the graft with scissors to fit the defect no fraying occurs at the cut edges.
The resorbable collagen dural graft offers an excellent solution that accelerates the surgical process by activating the body’s own healing ability and leaving no foreign material behind. Desu is a reliable partner in neurosurgery with collagen grafts that combine high purity, ideal resorption time, and flawless manipulation properties.
