New Method To Stop Cerebro-Spinal Fluid Leaks After TBI
Cerebro-spinal fluid (CSF) is the sterile fluid that bathes the brain and spinal cord and cushions them from trauma. Approximately 80% of all cases of leakage of CSF are caused by trauma with the rest occurring as a consequence of surgery. On March 23, 2014, Cook Medical (a medical products company headquartered in Bloomington, Indiana) announced the FDA had approved the use of its biomaterial to stop leakage of CSF from any cause. The device (known as the Biodesign® Dural Graft) is made from the lining of pig intestines which is sterilized and treated, leaving a paper-thin sheet with the ability to promote tissue regeneration wherever it is inserted. In time, the biomaterial is absorbed by the body.
