Very interesting. Though I wonder what the inflating balloon in your brain feels like...

"Over the course of several days, the balloon was slowly inflated, which spread delicate nerve fibers in the brain and created a safe pathway to the tumor. The child was continuously monitored for any adverse reaction. Once the pathway was of sufficient size to allow for surgical removal, the child was taken to the operating room. Dr. Crone deflated the balloon and, through the small opening, surgically removed the entire tumor. Although the patient was under anesthesia, Dr. Crone believes the procedure can be done in older children and adults while they are awake, which allows for better patient monitoring."
