Selection of neurostimulator parameter configurations using neural network
First Claim
1. A method comprising:
- selecting a first electrode configuration for a neurostimulator;
receiving an indication of observed efficacy of the first electrode configuration; and
iteratively selecting additional electrode configurations for the neurostimulator based on observed efficacies of preceding electrode configurations,wherein iteratively selecting the additional electrode configurations comprises applying the observed efficacies of the preceding electrode configurations to a neural network,wherein each of the electrode configurations defines a combination of two or more electrodes for delivery of neurostimulation therapy, andwherein the neural network comprises a plurality of interconnected nodes.

Abstract
In general, the invention is directed to a technique for selection of parameter configurations for a neurostimulator using neural networks. The technique may be employed by a programming device to allow a clinician to select parameter configurations, and then program an implantable neurostimulator to deliver therapy using the selected parameter configurations. The parameter configurations may include one or more of a variety of parameters, such as electrode configurations defining electrode combinations and polarities for an electrode set implanted in a patient. The electrode set may be carried by one or more implanted leads that are electrically coupled to the neurostimulator. In operation, the programming device executes a parameter configuration search algorithm to guide the clinician in the selection of parameter configurations. The search algorithm relies on a neural network that identifies potential optimum parameter configurations.
