Positioning system for neurological procedures in the brain
First Claim
1. Apparatus for use in a brain of a subject, comprising:
- an instrument, adapted to be inserted into the brain;
a set of one or more electrodes, adapted to be coupled to the instrument, and adapted to sense electrical activity of the brain and to transmit an electrical activity signal responsive thereto;
a location sensor, adapted to be coupled to the instrument and to transmit a location signal indicative of a location of the instrument; and
a control unit, adapted to analyze the electrical activity signal and the location signal, and adapted to determine, responsive to the analysis, a position of the instrument with respect to an image of the brain, and electrophysiological information regarding tissue at the position.

Abstract
Apparatus for use in a brain of a subject is provided, including an instrument, adapted to be inserted into the brain. A set of one or more electrodes, coupled to the instrument, are adapted to sense electrical activity of the brain and to transmit an electrical activity signal responsive thereto. A location sensor, adapted to be coupled to the instrument transmits a location signal indicative of a location of the instrument. A control unit, analyzes the electrical activity signal and the location signal. The control unit determines, responsive to the analysis, a position of the instrument with respect to an image of the brain, and electrophysiological information regarding tissue at the position.

33. A method for performing a medical procedure in a brain of a subject, comprising:
-
inserting an instrument into the brain;
sensing electrical activity of the brain in a vicinity of an electrical-activity sensing site on the instrument, and transmitting an electrical activity signal responsive thereto;
sensing, at a location-sensing site on the instrument, a location of the instrument, and transmitting a location signal responsive thereto;
determining, responsive to the location signal, a position of the instrument with respect to an image of the brain; and
determining, responsive to the electrical activity signal and the determination of the position, electrophysiological information regarding tissue at the position. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61)
