Methods and systems for controlling stimulation in paddle lead based on local impedances

An implantable pulse generator (IPG) configured to be electrically coupled to a paddle lead that includes a plurality of electrodes, the IPG comprising:

• a memory device;
• and
• a processing device communicatively coupled to the memory device, the processing device configured to:
• calculate an impedance for each electrode in a set of electrodes on the paddle lead, by measuring an impedance between each pair of electrodes in a trio of electrodes in the set of electrodes;
• determine at least one electrode in the set of electrodes having a lowest impedance within a predefined range;
• and
• automatically cause the paddle lead to perform stimulation using the at least one electrode.

A method for applying neurostimulation to a patient, the method comprising:

• electrically coupling a paddle lead to an implantable pulse generator (IPG), wherein the paddle lead includes a plurality of electrodes;
• calculating, using a processing device, an impedance for each electrode in a set of electrodes on the paddle lead, by measuring an impedance between each pair of electrodes in a trio of electrodes in the set of electrodes;
• determining, using the processing device, at least one electrode in the set of electrodes having a lowest impedance within a predefined range;
• and
• automatically causing the paddle lead to perform stimulation using the at least one electrode.
