Abstract
Methods and systems for planning configurations of a neuromodulation system having a lead with a plurality of electrodes. Configurations are planned using an optimizer that analyzes potential fractionalizations after removing unavailable electrodes from analysis and adjusting a candidate fractionalization to account for the removed electrodes. The unavailable electrodes may be identified by a physician or by analysis of impedances of the electrodes.
Claims20
A configuration system for configuring delivery of neuromodulation to specific tissue of a patient by an implantable system having a plurality of electrodes, the configuration system comprising:
- a receiver module configured to receive at least patient data for a patient and lead position indicating a location of a lead carrying at least two of the plurality of electrodes thereon relative to neural tissue of the patient;
- an optimizer for identifying candidate therapy parameter sets indicating utilization of the plurality of electrodes during therapy, the optimizer comprising:
- a steering module for identifying a potential fractionalization to analyze, the potential fractionalization setting proportions of total current to be issued by each of the electrodes;
- an electrode removal module that receives the potential fractionalization and removes unavailable electrodes from the potential fractionalization to generate a reduced fractionalization;
- an adjusting module that receives the reduced fractionalization and creates an adjusted fractionalization;
- a scoring module that receives the adjusted fractionalization and calculates a plurality of metrics for the adjusted fractionalization using a plurality of amplitude settings;
- and
- a candidate module that identifies one or more candidate therapies using the plurality of metrics.
