Abstract
Technology for deep brain stimulating including devices, systems, computer circuitry, and associated methods is provided. A deep brain stimulating device (100) can include a semiconductor substrate, an array of electrodes (140) coupled to the semiconductor substrate, and circuitry operable to control the array of electrodes (140). Each electrode (142) can be operable to function as an anode, a cathode, a common, or a float independent of other electrodes in the array to create highly configurable electric fields (122, 124).
Claims20
A deep brain stimulating device, comprising:
- a semiconductor substrate;
- an array of electrodes coupled to the semiconductor substrate, wherein each electrode is operable to function as an anode, a cathode, or a float independent of other electrodes in the array;
- and
- circuitry operable to control the array of electrodes.
A method of stimulating a neural region in vivo, comprising
- identifying a region of neural tissue to be electrically stimulated, wherein the region of neural tissue has a three dimensional area;
- inserting a stimulating electrode into a location in proximity to the region of neural tissue;
- and
- delivering an electric field from the stimulating electrode that substantially matches the three dimensional area of the region of neural tissue.
An array of electrodes for deep brain stimulation (DBS), having computer circuitry configured to:
- generate an electric field to stimulate a specified region of neural tissue using the array of electrodes, wherein each electrode is operable to function as an anode, a cathode, a common, or a float independent of other electrodes in the array;
- and
- adjust the electric field using a configurable pattern of pulses generated by the array of electrodes.
