摘要:
Selective high-frequency spinal chord modulation for inhibiting pain with reduced side affects and associated systems and methods are disclosed. In particular embodiments, high-frequency modulation in the range of from about 1.5 KHz to about 50 KHz may be applied to the patient's spinal chord region to address low back pain without creating unwanted sensory and/or motor side affects. In other embodiments, modulation in accordance with similar parameters can be applied to other spinal or peripheral locations to address other indications.

A tissue stimulation system is provided that evaluates and/or scores stimulation sets based on both patient feedback and frequency of use. Stimulation sets and any associated scores and/or usage may be stored in a retrievable database. Upon subsequent stimulation sessions, a patient may select stimulation sets that have a high score and/or usage in order to effectively meet therapeutic objectives. Methods of determining patient satisfaction, which involve evaluating patient pain before and after stimulation pulses are applied, are also provided herein.
摘要:
A method for determining whether the relative position of electrodes used by a neurostimulation system has changed within a patient comprises determining the amplitude of a field potential at each of at least one of the electrodes, determining if a change in each of the determined electric field amplitudes has occurred, and analyzing the change in each of the determined electric field amplitudes to determine whether a change in the relative position of the electrodes has occurred. Another method comprises measuring a first monopolar impedance between a first electrode and a reference electrode, measuring a second monopolar impedance between second electrode and the reference electrode, measuring a bipolar impedance between the first and second electrodes, and estimating an amplitude of a field potential at the second electrode based on the first and second monopolar impedances and the bipolar impedance.

Selective high-frequency spinal cord modulation for inhibiting pain with reduced side effects and associated systems and methods are disclosed. In particular embodiments, high-frequency modulation in the range of from about 1.5 KHz to about 100 KHz may be applied to the patient's spinal cord region from an epidural location to address phantom limb pain without creating paresthesia in the patient.

A method, computer medium, and system for programming a controller is provided. The controller controls electrical stimulation energy output to electrodes, and stores a set of programmed stimulation parameters associated with the electrodes. The programmed stimulation parameter set is compared with sets of reference stimulation parameters, each of the reference sets of stimulation parameters being associated with the electrodes. If an identical match is determined between the programmed stimulation parameter set and any one of the reference stimulation parameter sets exists based on the comparison, the identically matched stimulation parameter set is selected as an initial stimulation parameter set. If an identical match does not exist, a best between the programmed stimulation parameter set and the reference stimulation parameter sets is determined and selected as the initial stimulation parameter set. The controller is then programmed with a new set of programmable stimulation parameters based on the initial stimulation parameter set.

摘要:
A method of transitioning stimulation energy (e.g., electrical stimulation pulses) between a plurality of electrodes implanted within a patient is provided. The method comprises selecting a plurality of stimulation output values (e.g., electrical current amplitude values) for each of the electrodes. The method further comprises selecting a plurality of different modification values for at least one of the electrodes, respectively multiplying the stimulation output values and the modification values to determine modified stimulation output values for the electrode(s), which may optionally be stored in a steering table, and incrementally transitioning the stimulation energy to or from the electrode(s) in accordance with the modified stimulation output values. The modified stimulation output values are stored in a steering table. The modification values may be selected in a manner that maintains paresthesia when transitioning the stimulation energy between the electrodes.
