Abstract: Implantable medical leads include rows of electrode segments where electrode segments within a given row may be a different size and/or adjacent electrode segments of adjacent rows may be of a different size. The arrangement of the electrode segments of different sizes may avoid intersections of the spaces between segments to reduce the size and/or number of blind spots that otherwise occur for delivery of stimulation signals and/or sensing of physiological signals. The electrode segments of different sizes may be of a same shape type but with different proportions.

Abstract: Devices, systems, and techniques are described for identifying stimulation parameter values based on electrical stimulation that induces dyskinesia for the patient. For example, a method may include controlling, by processing circuitry, a medical device to deliver electrical stimulation to a portion of a brain of a patient, receiving, by the processing circuitry, information representative of an electrical signal sensed from the brain after delivery of the electrical stimulation, determining, by the processing circuitry and from the information representative of the electrical signal, a peak in a spectral power of the electrical signal at a second frequency lower than a first frequency of the electrical stimulation, and responsive to determining the peak in the spectral power of the electrical signal at the second frequency, performing, by the processing circuitry, an action.

Abstract: An example system includes electrical stimulation circuitry configured to generate electrical stimulation, electrodes configured to deliver the electrical stimulation to a patient, and processing circuitry configured to determine, for a patient, a first cycling of electric stimulation doses. The processing circuitry is also configured to deliver the electric stimulation doses according the determined first cycling, receive patient feedback representing a response of the patient to the electric stimulation doses delivered according to the first cycling, determine, based on the patient feedback, a second cycling of the electric stimulation doses, and deliver the electric stimulation doses to the patient according the determined second cycling. Delivering the electric stimulation doses for the patient according to the determined second cycling consumes less power of the implanted device than delivering the electric stimulation doses for the patient according to the determined first cycling.

Abstract: Devices, systems, and techniques for identifying electrodes closest to a target region of tissue are described. In one example, a device includes sensing circuitry configured to sense electrical signals from a plurality of electrode combinations. Processing circuitry identifies a first electrode combination of a first subset of electrode combinations. Each electrode combination of the first subset of electrode combination includes electrodes located at different axial positions along a length of the medical lead. The processing circuitry identifies a second electrode combination of a second subset of electrode combinations. Each electrode combination of the second subset of electrode combinations includes electrodes located at a same axial position and different circumferential positions around a perimeter of the medical lead. The processing circuitry then determines a third electrode combination and controls delivery of electrical stimulation via the third electrode combination.

Abstract: Devices, systems, and techniques for monopolar recording of sensed electrical signals are disclosed. An example device includes sensing circuitry configured to sense electrical signals from a first plurality of electrode combinations, each of the first plurality of electrode combinations comprising a same reference electrode of the plurality of electrodes and at least one different sense electrode of the plurality of electrodes, the plurality of electrodes being associated with one or more leads. The example device includes processing circuitry configured to record the sensed electrical signals from the first plurality of electrode combinations. The processing circuitry is also configured to provide representations of the recorded sensed electrical signals.
