Watertight Dural Graft Patch Solutions
Every incision made in neurosurgery helps the surgeon access brain tissue, but it also breaches the dura mater, brain’s natural protective layer. The success of the surgery depends not only on removing the tumor or clipping the aneurysm, but also on how securely this protective layer is closed after surgery. If the dura mater cannot be closed with sutures initially, or if there is a possibility of cerebrospinal fluid leakage from the suture sites, watertight dural graft patch systems come into play. Desu offers biomaterial engineering marvels in the form of leak proof patch solutions to prevent postoperative CSF leaks and associated infections, which are the biggest concern for surgeons.
In a dural patch, being watertight is not a preference but a necessity. This is because cerebrospinal fluid has a fluid like consistency and carries the risk of leaking through even the smallest micro holes. Traditional methods or standard patches may be insufficient in situations where intracranial pressure increases, such as during coughing or straining. The Watertight dural graft patch developed by Desu Medical creates an effective barrier against intracranial pressure fluctuations with its high burst pressure resistant structure.
Watertight Dural Graft Patch with Sutureless Application
Reducing surgical time is a major goal in modern neurosurgery. Traditional patches require the surgeon to place numerous sutures to achieve watertightness. This is both time consuming and each needle entry creates a new potential leak. Desu Medical’s watertight dural graft patch technologies have been developed to be compatible with the overlay technique.
In this method, when the patch is placed over the injury, it automatically adheres to the tissue upon contact with CSF. The high adhesion properties of Desu Medical’s patches reduce or completely eliminate the need for sutures. Even in suture free applications, the watertight dural graft patch does not shift from its position as long as intracranial pressure remains at normal levels. This feature offers the surgeon great comfort and safety, especially in cases such as hard to reach skull base surgeries or spinal dural repairs.
Biocompatibility and Regeneration in Watertight Dural Graft Patches
When any foreign object is placed in the body, there is a risk of a reaction. However, Desu Medical’s dura patches function in accordance with the principles of regenerative medicine. Rather than being a permanent implant, the waterproof dural graft patch acts as a structure on which the patient’s own cells grow to form new dura tissue.
During the healing process, fibroblasts, or connective tissue cells, migrate toward the porous structure of the patch. The waterproof dural graft patch has a smart structure that allows these cells to move while preventing fluid passage. Over time, as the patch is absorbed by the body, it is replaced by the patient’s own natural, living, and waterproof dura tissue. Desu Medical applies special cross-linking techniques that ensure the patch remains intact without premature dissolution and maintains its impermeability during this transformation. This ensures the safety barrier remains open until the healing process is complete.
Why Choose Desu Medical’s Waterproof Dural Graft Patches?
Although there are various dura patches on the market, the reasons surgeons choose Desu Medical include stability and safety. Every surgeon knows that the expected performance of the product placed on the table should not be left to chance. Desu relies on international quality standards (ISO 13485, CE, FDA compliance processes) in the production of its waterproof dural graft patches.
The products are sterilized using methods such as gamma sterilization or ethylene oxide, ensuring that the molecular structure of the material is not compromised. Desu Medical’s patches are transparent or semi-transparent, allowing the surgeon to see the cerebral cortex and blood vessels beneath the patch, which facilitates control over potential bleeding. Their ergonomic design, which does not disintegrate upon contact with blood, maintains its shape, and does not stick to the surgeon’s instruments, makes Desu Medical’s waterproof dural graft patches an indispensable product.
The Versatility of Waterproof Dural Graft Patches in Neurosurgery
The use of these patches is not limited to trauma or tumor surgery:
- Chiari Malformation: During decompression, when increasing volume with a dura patch, waterproofing is a prerequisite.
- Spinal Surgery: Used to prevent pressurized CSF leakage in tears that occur during spinal cord surgery.
- Transsphenoidal Surgery: In pituitary tumor surgeries performed through the nose, a strong, waterproof dural graft patch is essential for closing the skull base.
Desu offers patch options in different sizes and thicknesses, aiming to meet surgeons’ needs on a case by case basis. Brain surgery is an extremely delicate field where even millimeter errors are unacceptable. Waterproof dural graft patches stand out as the most important tool for surgeons in this field. A leak proof, biocompatible, and easy to apply patch allows patients to be discharged quickly and return to their normal lives without complications.
Desu continues to offer safe solutions to the field of neurosurgery with its dura patches developed through its expertise in tissue engineering.
