DuraSeal™ is a new, synthetic gel designed to seal the sutured dura following cranial neurosurgical procedures. It has been approved by the FDA last week. The dura mater is the outermost tough membrane surrounding the brain and the spinal cord. The cerebrospinal fluid leakage through incompletely closed dura can cause persistent, often severe, headache, meningitis, or even death.
Confluent Surgical, Inc. describes its product:
DuraSeal™ is a new, synthetic hydrogel designed to augment sutured dura closures following cranial surgical procedures. The device can be stored at room temperature and prepared in minutes. A blue dye has been added to DuraSeal, which allows for improved visualization. When sprayed on tissue, a strong, adherent hydrogel layer is produced, effectively sealing the suture line.
The hydrogel continues to seal the suture line as healing progresses under the gel. After several months the hydrogel breaks down into water-soluble molecules that are absorbed and cleared through the kidneys.
