Abstract
An intracranial apparatus that may be used for electrophysiological monitoring and stimulation of brain tissue of a patient. Embodiments comprise a stylet including a body section and a tip configured to separate brain tissue, a sheath including a body section having an outer surface defining a central opening configured to receive the stylet such that the tip of the stylet extends beyond the body section of the sheath, and a plurality of electrodes disposed at the outer surface of the sheath and configured to be connected to the brain tissue surrounding the sheath for stimulating and/or monitoring.
Claims19
An intracranial apparatus for providing electrophysiological monitoring and stimulation of brain tissue of a patient, the apparatus comprising:
- a stylet including a body section and a tip configured to separate brain tissue;
- a sheath including a body section having an outer surface and defines a central opening configured to receive the stylet such that the tip of the stylet extends beyond the body section of the sheath;
- and
- a plurality of electrodes disposed at the outer surface of the sheath and configured to be connected to the brain tissue surrounding the sheath for stimulating and monitoring.
A method of using an intracranial apparatus including a stylet, a sheath defining a central opening configured to receive the stylet, and a plurality of electrodes disposed at an outer surface of the sheath, the method comprising:
- inserting the apparatus into a brain such that the brain tissue of the brain is separated by the stylet and in contact with the plurality of electrodes disposed at the outer surface of the sheath;
- removing the stylet from the brain while the sheath remains in contact with the brain tissue;
- monitoring and/or stimulating the brain using the plurality of electrodes;
- identifying one or more sites of surgical interest based on the data from monitoring and/or stimulation of the brain;
- resecting brain tissue at the one or more sites of surgical interest while the sheath is in contact with the brain tissue;
- and
- removing the sheath from the brain after resecting.
