First Claim
Patent Images
1. A method of providing therapy to a patient using at least one electrode implanted within an epidural space in the patient, comprising:
- modulating neural elements within a dorsal horn without causing the patient to perceive paresthesia, wherein modulating the neural elements within the dorsal horn includes delivering pulsed electrical current from the at least one electrode within the epidural space into a spinal cord tissue of the patient, wherein the pulsed electrical current has a defined pulse width less than 100 μ
s and a defined pulse rate equal to or less than 500 Hz.

Abstract
A method of providing therapy to a patient. The method comprises conveying pulsed electrical current at a defined pulse width and a defined pulse rate into spinal cord tissue. The defined pulse width is equal to or less than 200 μs, and the defined pulse rate is less than 1500 Hz, such that neural elements in the dorsal horn are modulated and/or the patient does not perceive paresthesia during the conveyance of the pulsed electrical current into the spinal cord tissue.

13. A method of providing therapy to a patient using at least one electrode implanted within an epidural space in the patient, comprising:
delivering pulsed electrical current at a defined pulse width and a defined pulse rate from the at least one electrode within the epidural space into spinal cord tissue of the patient to modulate neural elements within a dorsal horn, wherein the defined pulse width is equal to or less than 200 μ
s, the defined pulse rate is equal to or less than 500 Hz, and the defined pulsed amplitude is small enough, such that the patient does not feel paresthesia during the delivery of the pulsed electrical current into the spinal cord tissue.- View Dependent Claims (14, 15, 16, 17, 18, 19, 20)

21. A method of providing therapy to a patient using at least one electrode implanted within an epidural space in the patient, comprising:
preferentially modulating neural elements within a dorsal horn over dorsal column fibers to effectively deliver the therapy without causing patient-perceived paresthesia, wherein preferentially modulating the neural elements within the dorsal horn includes delivering pulsed electrical current from the at least one electrode within the epidural space into a spinal cord tissue of the patient, the pulsed electrical current having a defined pulse width equal to or less than 200 μ
s and a defined pulse rate equal to or less than 500 Hz.
