Abstract
This invention provides an apparatus for electrically stimulating a cell and a method for using the same. In particular, the apparatus of the invention comprises an array of electrodes and a controller for actuating individual electrodes.
Claims19
An apparatus for electrically stimulating a cell in a subject, said apparatus consisting of:
- an array of electrodes configured to be implanted in said subject, wherein said array of electrodes comprises an arrangement of individual electrodes;
- and
- a controller operatively connected to said array of electrodes for actuating the individual electrodes, wherein said controller is configured to actuate at least one of the individual electrodes as a stimulating electric field producing electrode, and wherein said controller is further configured to actuate said stimulating electric field producing electrode to produce a transverse stimulation electric field to the cell,
- wherein said controller is configured to produce said transverse stimulation electric field for the duration of less than 20 μsec.
1 more element
An apparatus for electrically stimulating a cell in a subject, said apparatus consisting of:
- an array of individual electrodes configured to be implanted in said subject;
- and
- a controller operatively connected to said array of individual electrodes and adapted for actuating said individual electrodes, wherein said controller is configured to actuate at least one of the individual electrodes as a stimulating electric field producing electrode to produce a cell stimulating electric field of less than 20 μsec duration and at least one other of said individual electrodes as a field shaping electrode to produce a guiding electric field, wherein the presence of said guiding electric field increases the strength of said stimulating electric field to the cell relative to the strength of said stimulating electric field to the cell in the absence of said guiding electric field.
