  • Publication number: 20140277284
    Abstract: A system and method include a processor that, based on at least a subset of stored data of clinical effects of one or more stimulations of anatomical tissue performed using electrodes of an implanted leadwire, generates and outputs at least one graphical marking representing the at least the subset of the stored data. Each of the at least one graphical marking represents a respective portion of the at least the subset of the stored data and is output in association with a respective set of values for each of at least two parameters by which one or more the stimulations were performed. The markings are plotted in a graph defined by axes corresponding to values of respective stimulation parameters. Alternative, the markings are arranged in a column of a tabular report. The markings are two-toned to provide respective information for both therapeutic and adverse side effects.

  • Publication number: 20140277267
    Abstract: An external control device and method for programming an implantable neuromodulator coupled to an electrode array implanted adjacent tissue of a patient having a medical condition. Electrical modulation energy is conveyed to tissue of the patient in accordance with a series of modulation parameter sets. The patient perceives paresthesia in response to the conveyance of the electrical modulation energy to the tissue in accordance with at least one of the modulation parameter sets. One of the modulation parameter set(s) is identified based on the perceived paresthesia. Another modulation parameter set is derived from the identified modulation parameter set. Electrical modulation energy is conveyed to the tissue of the patient in accordance with the other modulation parameter set without causing the patient to perceive paresthesia.

  • Publication number: 20140180349
    Abstract: A neuromodulation system and method for managing electrical neuromodulation therapy for a patient in conjunction with administering a pharmacological agent to the patient. Electrical energy is delivered to a target tissue region of the patient, thereby electrically modulating the target tissue region providing therapy to the patient. The energy level of the electrical energy delivered to the tissue is automatically varied inversely to the effect of the pharmacological agent on the patient during a therapeutic window. An absorption level of the pharmacological agent in the patient may be continually detected, and the energy level of the delivered electrical energy automatically varied based on the detected absorption level of the pharmacological agent during a therapeutic window.

  • Publication number: 20140148874
    Abstract: A system for a neurostimulator coupled to electrodes, and a method of providing therapy to a patient using the electrodes implanted within the patient. A target multipole relative to the electrodes is defined. The target multipole is emulated by defining an initial electrical current distribution for the electrodes, such that a first set of active electrodes respectively has electrical current values of a first polarity. Each of the electrical current values of the first polarity is compared to a first threshold value, and at least one of the electrodes in the first active electrode set is zeroed-out based on the comparison. The electrical current value of each of the zeroed-out electrode(s) is redistributed to remaining ones of the electrodes to define a new electrical current distribution for the electrodes. Electrical current is conveyed to the electrodes in accordance with the new electrical current distribution, thereby providing the therapy.

  • Publication number: 20120290040
    Abstract: A neurostimulation system for management of stimulation safety limits. The system determines a tissue charge injection metric at each electrode, compares the metric to the hard stop charge limit, and prevents the neurostimulator from delivering stimulation energy to the tissue region in accordance based on the comparison. The hard stop limit may be user-programmable or may be automatically modified in response to detection of electrode characteristics. The system may quantitatively notify a user of a value of the injected charge injected into the tissue. The electrodes may be organized into different sets, in which case, the system may directly control tissue charge independently at each of the electrode sets. If current steering is provided, the system may displace the electrical stimulation energy along the tissue region in one direction, while preventing the charge injection value at each of the electrodes from meeting or exceeding the hard stop charge limit.
