摘要： The present invention relates to a system, comprising an external system and a stimulator; wherein the external system is configured to determine a model for the patient during a testing procedure performed on the patient, wherein the model is indicative of a range or volume of preferred stimulation parameters; wherein the external system is configured to receive a plurality of pieces of fitting information for the patient; wherein the external system is configured to determine one or more sets of stimulation parameters for the patient using the pieces of fitting information, wherein the one or more sets of stimulation parameters are selected from the range or volume of preferred stimulation parameters; and wherein the external system is configured to program the stimulator device with at least one of the one or more sets of stimulation parameters.

摘要： Methods and systems for testing and treating spinal cord stimulation (SCS) patients are disclosed. Patients are eventually treated with sub-perception (paresthesia free) therapy. However, supra-perception stimulation is used during "sweet spot searching" during which active electrodes are selected for the patient. This allows sweet spot searching to occur much more quickly and without the need to wash in the various electrode combinations that are tried. After selecting electrodes using supra-perception therapy, therapy is titrated to sub-perception levels using the selected electrodes. Such sub-perception therapy has been investigated using pulses at or below 10 kHz, and it has been determined that a statistically significant correlation exists between pulse width (PW) and frequency (F) in this frequency range at which SCS patients experience significant reduction in symptoms such as back pain. Beneficially, sub-perception stimulation at such low frequencies significantly lowers power consumption in the patient's neurostimulator.

摘要： Methods and systems for assisting a patient to reprogram parameters of an implantable medical device, such as a spinal cord stimulator, are disclosed. A patient may use an external controller, which may be either a dedicated device or a personal computing device, to interact with their implantable medical device and evaluate the efficacy of their therapy. If the efficacy diminishes, the patient may use their external controller to adjust either the neural dosage (i.e., frequency, pulse width, and/or amplitude) and/or the location at which stimulation is provided. A reprogramming assistant is provided, which guides the patient in adjusting their stimulation using their external controller. The patient may use supra-perception or sub-perception stimulation for the adjustment. The implantable medical device may include pre-programmed "rescue programs" to assist the patient in recovering the efficacy of their therapy.

摘要： The present invention relates to a system for providing stimulation to a patient, the system comprising: an implantable stimulator device, ISD, that is implantable in the patient and an external controller configured to control the implantable stimulator device, wherein the external controller is configured to track instances when the patient uses the external controller to instruct the ISD to issue a bolus of stimulation, wherein the bolus of stimulation comprises active stimulation for a first period of time and wherein after the first period of time the ISD provides no stimulation for a second period of time, correlate the tracked instances with one or more predictors indicative of a need for stimulation, determining an occurrence of one or more of the predictors, and in response to the occurrence, (i) prompt the patient to issue a bolus of stimulation; or (ii) automatically instructing the ISD to issue a bolus of stimulation.

摘要： A method is disclosed for programming a patient's stimulator device using an external device. The method provides a Graphical User Interface (GUI) on the external device that allows the patient to select from a plurality of displayed stimulation modes to program stimulation provided by one or more electrodes of the stimulator device. The external device stores a model derived for the patient, which model comprises information indicative of a plurality of frequency/pulse width/amplitude coordinates predicted to provide optimal stimulation for the patient. Each stimulation mode corresponds with a subset of coordinates defined in accordance with the plurality of coordinates in the model. Selection of one of the stimulation modes limits programming the stimulator device with coordinates that are within the corresponding subset of coordinates.
