System and method for estimating location and depth of stimulation leads
First Claim
1. An external control device for use with a stimulation device capable of conveying an electrical signal to a stimulation lead implanted within a patient, and measuring an electrical parameter in response to the conveyance of the electrical signal, comprising:
- telemetry circuitry configured for communicating with a stimulation device;
a processor configured for receiving the measured electrical parameter from the stimulation device via the telemetry circuitry, selecting one of a plurality of different anatomical regions in which the stimulation lead is implanted based on the measured electrical parameter, and defining a stimulation parameter based on the selected anatomical region; and
a controller configured for instructing the stimulation device via the telemetry circuitry to convey electrical stimulation energy from the stimulation lead in accordance with the defined stimulation parameter.

Abstract
A method and external control device for performing a medical procedure on a patient in which at least one stimulation lead is implanted. An electrical signal is conveyed from the stimulation lead into tissue of the patient. An electrical parameter indicative of tissue impedance is measured in response to the conveyance of the electrical signal. One of a plurality of different anatomical regions in which the stimulation lead is implanted is selected and/or a depth in which the stimulation is implanted is determined based on the measured electrical parameter. A stimulation parameter is defined based on the selected one anatomical region and/or implantation depth. Electrical stimulation energy from the stimulation lead is conveyed into the one determined anatomical region in accordance with the defined stimulation parameter.
