ARTIFASCIA®
Today, neurosurgeons often use a graft and a liquid sealant to repair the Dura and prevent cerebral-spinal fluid (CSF) leakage after neurosurgeries. Despite this, there still up to 30% chance of leakage after surgery. CSF leakage is highly dangerous to the patient and can result in long hospitalization and even a repeated surgery.
Nurami Medical’s ArtiFascia® for dural repair is a porous nanofiber graft made of medical grade synthetic polymers that addresses this problem. The graft incorporates biodegradable nanofibers, to boost dural regeneration, and a novel, temperature-sensitive viscoelastic sealant to prevent cerebral-spinal fluid (CSF) leakage. The use of ArtiFascia will eliminate the need to use a liquid sealant in addition to the graft, significantly reduce the chance of CSF leakage and enhance patient’s healing and recovery after neurosurgery.
ArtiFasica® is under clinical investigation and was implanted in over 12 patients.
ArtiFascia’s® thickness is comparable to human dura, and it is applied via a routine procedure. ArtiFascia’s® mechanical strength and flexibility enables for robust suturing, convenient handling and pliability that allows the device to conform to the surface of the dural defect without dangerous adhesions while maintaining a mechanical barrier against leakage. The patch degrades naturally over time, and is replaced by the native tissue with complete dural closure.
Nurami Medical’s ArtiFascia® is the first multifunctional nanofiber-based tissue reconstruction patch that combines two functions in a single device
1
The porous nanofiber patch mimics natural extracellular matrices, providing a scaffold, which enables infiltration of fibroblasts and cells from the intact tissue, enhancing tissue regeneration, ultimately replacing damaged dural tissue.
2
The temperature-sensitive and visco-elastic sealant becomes a deformable gel that penetrates suture holes and conforms to fibers, even when stretched. This novel gel eliminates the need for surgical sealants, ensuring watertight sealing of the site, reducing CSF leakage and potentially life-entry of threatening pathogens.

In-vivo testing of ArtiFasciaTM has validated its supremacy over the state of the art, in terms of preventing leakage, mechanical strength, regeneration capabilities, tissue integration, suture retention and more.
