Method and System for Determining Settings for Deep Brain Stimulation

A method comprising:

• applying, via a probe, test stimulation to a tissue of a patient;
• measuring a result of the test stimulation and determining therefrom at least one of an impedance value or an admittance value of the tissue;
• determining a target field that will stimulate a selected portion of the tissue;
• and
• determining, via a processor, and based on the at least one of the impedance value or admittance value of the tissue, one or more stimulation settings to generate the target field that will stimulate the selected portion of the tissue,
• wherein determining the target field that will stimulate a selected portion of the tissue comprises receiving an indication of anatomical structures for which stimulation should be avoided.

• wherein determining the target field that will stimulate a selected portion of the tissue comprises receiving a set of coordinates of positions of one or more target anatomical structures.

A system comprising:

• a probe comprising multiple electrodes;
• and
• a processor configured to:
• receive an indication of a target field that will stimulate a selected portion of tissue of a patient,
• control delivery of test stimulation to the tissue of the patient,
• obtain a measure of one or more signals resulting from the test stimulation,
• determine at least one of an impedance value or an admittance value of the tissue based on the test stimulation and the measure of the one or more signals, and
• determine, based on the at least one of the impedance value or the admittance value of the tissue, one or more stimulation settings to generate the target field that will stimulate the selected portion of tissue of the patient,
• wherein the indication of the target field comprises an indication of one or more positions of anatomical structures for which stimulation should be avoided.

An implantable device, comprising:

• a probe comprising multiple electrodes;
• and
• a processor configured to receive an indication of a target field that will stimulate a selected portion of tissue of a patient, and further to determine one or more stimulation settings to generate the target field that will stimulate the selected portion of tissue of the patient based on a test stimulation provided via at least one of the multiple electrodes and at least one of an impedance value or an admittance value of the tissue determined from signals resulting from the test stimulation that are obtained via one or more of the multiple electrodes,
• wherein the indication of the target field comprises an indication of one or more positions of anatomical structures for which stimulation should be avoided.
