Subpial transector is designed to treat epilepsy when the seizure focus is in a cortical area that cannot be surgically resected without causing an unacceptable neurological deficit. It cuts fine parallel in the cortical surface to disrupt the initial spread of the seizure discharge without compromising the vertical organization of the cortex.
A suction catheter is a flexible, long tube attached on one end to the breathing tube. The other end of the suction catheter is connected to a collection container and a device that generates suction. The frequency of suctioning is determined by the amount of secretions that the patient produces. The breathing tube is suctioned whenever fluid builds up in the lungs.
