Abstract
A method and neurostimulation system of providing therapy to a patient is provided. At least one electrode is place in contact with tissue of a patient. A sub-threshold, hyperpolarizing, conditioning pre-pulse (e.g., an anodic pulse) is conveyed from the electrode(s) to render a first region of the tissue (e.g., dorsal root fibers) less excitable to stimulation, and a depolarizing stimulation pulse (e.g., a cathodic pulse) is conveyed from the electrode(s) to stimulate a second different region of the tissue (e.g., dorsal column fibers). The conditioning pre-pulse has a relatively short duration (e.g., less than 200 μs).

18. A neurostimulation system, comprising:
-
a plurality of electrical contacts; analog output circuitry capable of outputting electrical pulses to the plurality of electrical contacts in accordance with a pulse pattern; and control circuitry capable of defining the pulse pattern, such that the electrical pulses comprise a sub-threshold, conditioning, pre-pulse outputted to a first one of the electrical contacts, and a stimulation pulse outputted to a second different one of the electrical contacts, wherein the conditioning pre-pulse is equal to or shorter than the stimulation pulse. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
