Active implantable medical device with automatic optimization of the configuration of a multi-electrode stimulation lead
First Claim
1. A method for configuration of an implantable neurostimulation device comprising:
- recording one or more physiological parameters using a sensing lead and a sensing electrode of the implantable neurostimulation device;
setting, by a control circuit of the implantable neurostimulation device, a first stimulation configuration with at least one of a first energy, a first pulse amplitude, or a first number of pulses;
determining, by the control circuit, if conditions of stability of a patient'"'"'s condition are met, and if so, delivering the first stimulation to a nerve by a stimulation lead; and
repeating delivery of the first stimulation while testing a plurality of configurations of a set of stimulation electrodes;
wherein testing the plurality of configurations of the set of stimulation electrodes comprises;
storing the measured physiological parameters of each of the plurality of configurations;
changing, by the control circuit, the configuration of the set of stimulation electrodes; and
determining a selected configuration that produces a best calculated effect on the recorded one or more physiological parameters.

Abstract
A device includes a pulse generator coupled to a neurostimulation lead placed around the nerve and a set of electrodes individually connected to the generator by a splitter circuit controlled to preferentially stimulate certain regions of the nerve relative to other regions. The device performing an iterative search of an optimal configuration operating by selection of a plurality of different stimulation configurations, storing of a cardiac physiological parameter measured for each selected stimulation configuration, and designation as optimal stimulation configuration of the one of said selected different stimulation configurations, depending on at least the stored values of the physiological parameter measured for different electrode configurations.
