Abstract
A method for treatment of a brain and/or spinal cord includes inserting a flexible catheter into a cerebrospinal fluid space, the flexible catheter including two lumens adapted to allow a fluid to circulate therein in a closed loop within the flexible catheter and the flexible catheter being adapted to be connected to a device for cooling and circulating the fluid. The cerebrospinal fluid in the cerebrospinal fluid space is cooled with the flexible catheter to enable selective central nervous system cooling. The functional status of the brain and/or spinal cord is monitored, and the treatment of the brain and/or spinal cord is modified to adjust for any change in the functional status of the brain and/or spinal cord.
Claims18
A method for treatment of a nervous system, the method comprising:
- inserting a flexible catheter including a drainage lumen into a cerebrospinal fluid space;
- draining cerebrospinal fluid through the drainage lumen in the catheter to decrease pressure in the nervous system;
- monitoring a functional status of thoracic spinal cord evoked potentials of the nervous system;
- monitoring a functional status of cervical spinal cord evoked potentials of the nervous system;
- and
- modifying the treatment of the nervous system to adjust for any change in the functional status of the thoracic spinal cord evoked potentials of the nervous system relative to the functional status of the cervical spinal cord evoked potentials of the nervous system.
