System and method for determining the neurological position of epidural leads
First Claim
1. A method for placing an electrode arrangement for use to deliver a therapeutic modulation field to a therapeutic modulation target, comprising:
- inserting an electrode arrangement into an epidural space and moving the electrode arrangement within the epidural space; and
monitoring a position of the electrode arrangement with respect to a supra-perception dorsal root target to position the electrode arrangement in a desired position within the epidural space to deliver the therapeutic modulation field to the therapeutic modulation target, the supra-perception dorsal root target being different from the therapeutic modulation target, wherein the monitoring includes;
delivering supra-perception threshold stimulation from the electrode arrangement in the epidural space to dorsal roots;
receiving patient-perception information for the supra-perception threshold stimulation delivered to the dorsal roots, the patient-perception information indicating that the electrode arrangement is in the desired position when the supra-perception threshold stimulation stimulates the supra-perception dorsal root target; and
placing the electrode arrangement in the desired position within the epidural space using the patient-perception information.

Abstract
An system may include an electrode arrangement configured for implantation in an epidural space, a neural modulation generator configured to use electrodes in the electrode arrangement to generate modulation fields, at least one storage and a controller operably connected to the neural modulation generator. The storage(s) may be configured to store supra-perception threshold dorsal root modulation field parameter data and therapeutic modulation field parameter data, where the therapeutic modulation field parameter data may be different than the supra-perception threshold dorsal root modulation field parameter data. The system may be configured to deliver a placement modulation field from the electrode arrangement in the epidural space to the dorsal roots using the supra-perception threshold dorsal root modulation field parameter data, and deliver a therapeutic modulation field from the electrode arrangement placed in the desired position within the epidural space to a therapeutic neural target using the therapeutic modulation field parameter data.

4. A method, comprising:
-
performing a placement procedure, including; delivering supra-perception threshold modulation from an electrode arrangement in the epidural space to dorsal roots; receiving patient-perception information for the supra-perception threshold modulation delivered to the dorsal roots; and using the patient-perception information to either place the electrode arrangement in a desired position within the epidural space where the supra-perception threshold modulation stimulates a supra-perception dorsal root target or place a supra-perception modulation field to modulate the supra-perception dorsal root target; and delivering therapeutic neural modulation to a therapeutic modulation target using the electrode arrangement in the desired position within the epidural space or using therapeutic modulation parameters derived from parameters used to place the supra-perception modulation field, the supra-perception dorsal root target being different from the therapeutic modulation target. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14)
