Systems and methods for improved spinal cord stimulation
First Claim
1. A patient treatment system comprising:
- an implantable pulse generator programmed to provide a first pulsed electrical signal having at least one frequency selected within the range of from about 1 kHz to about 100 kHz;
the implantable pulse generator having at least a first implantable electrical lead with a first set of electrical contacts adapted to be located adjacent a patient'"'"'s spinal cord for delivering the first pulsed electrical signal to at least one location along said patient'"'"'s spinal cord to treat pain in the patient through application of the first pulsed electrical signal, the implantable pulse generator further configured to adjust the first pulsed electrical signal amplitude based upon at least one impedance measurement;
the implantable pulse generator being configured to provide the first pulsed electrical signal without the first pulsed electrical signal producing an unwanted side-effect related to sensory processing.

Abstract
Stimulation treatments for various medical disorders, such as neurological disorders, comprise novel systems, strategies, and methods for providing TMS, electrical, magnetic, optical and other stimulation modalities. Some stimulation methods comprise varying the stimulation parameters to improve the therapeutic efficacy of stimulation, and decrease risk of habituation and side-effects such as interference with normal brain, sensory, motor, and cognitive processes. The creation, and subsequent variation, of stimulation parameters can use sensed data in order to match, adjust, or avoid matching characteristics of the stimulation therapy relative to certain endogenous brain activities. Novel methods are described for choosing, creating and subsequently stimulating with partial signals which summate to produce therapeutic vector fields having unique temporal patterns and low- or high-frequency spectral content. Improvements for the treatment of pain are disclosed.
