Abstract
Devices, systems, and techniques are disclosed for managing electrical stimulation therapy and/or sensing of physiological signals such as brain signals. For example, a system may assist a clinician in identifying one or more electrode combinations for sensing a brain signal. In another example, a user interface may display brain signal information and values of a stimulation parameter at least partially defining electrical stimulation delivered to a patient when the brain signal information was sensed.
Claims24
A method comprising:
- receiving, by processing circuitry, signal information indicative of first electrical signals sensed from a brain tissue and by a plurality of electrode combinations at a second time, each electrode combination comprising an electrode carried by a lead, wherein the lead defines a longitudinal axis and comprises a plurality of electrodes disposed at different circumferential positions around the longitudinal axis of the lead;
- determining, by the processing circuitry and based on the signal information and initial information indicative of second electrical signals sensed from the plurality of electrode combinations at a first time prior to the second time, that the lead has rotated with respect to the brain tissue;
- and
- outputting, by the processing circuitry, an indication that the lead has rotated with respect to the brain tissue.
A system comprising:
- a memory configured to store initial information indicative of first electrical signals sensed from a brain tissue and by a plurality of electrode combinations at a first time, each electrode combination comprising an electrode carried by a lead, wherein the lead defines a longitudinal axis and comprises a plurality of electrodes disposed at different circumferential positions around the longitudinal axis of the lead;
- and
- processing circuitry configured to:
- receive signal information indicative of second electrical signals sensed from the plurality of electrode combinations at a second time after the first time;
- determine, based on the signal information, that the lead has rotated with respect to brain tissue;
- and
- output an indication that the lead has rotated with respect to the brain tissue.
A computer-readable storage medium comprising instructions that, when executed, cause processing circuitry to:
- receive signal information indicative of first electrical signals sensed from a brain tissue and by a plurality of electrode combinations at a second time, each electrode combination comprising an electrode carried by a lead, wherein the lead defines a longitudinal axis and comprises a plurality of electrodes disposed at different circumferential positions around the longitudinal axis of the lead;
- determine, based on the signal information and initial information indicative of second electrical signals sensed from the plurality of electrode combinations at a first time prior to the second time, that the lead has rotated with respect to brain tissue;
- and
- output an indication that the lead has rotated with respect to the brain tissue.
