Methods and apparatuses for setting a therapeutic dose of a neuromodulator implanted into a patient. The therapeutic dose typically includes a therapeutic dose duration including a ramp-up time to reach a peak modulation voltage and a sustained peak modulation time during which the voltage is sustained at the peak modulation voltage. The methods and apparatuses may use a testing ramp to identify a peak modulation voltage that is patient-specific and provides a maximized therapeutic effect while remaining comfortably tolerable by the patient during the application of energy by the neuromodulator.

A method of treating a patient and on external programmer for use with a neurostimulator. Electrical stimulation energy is conveyed into tissue of the patient via a specified combination of a plurality of electrodes, thereby creating one or more clinical effects. An influence of the specified electrode combination on the clinical effect(s) is determined. An anatomical region of interest is displayed in registration with a graphical representation of the plurality of electrodes. The displayed anatomical region of interest is modified based on the determined influence of the specified electrode combination on the clinical effect(s).

Described herein are systems and methods for the treatment of pain using electrical nerve conduction block (ENCB). Contrary to other methods of pain treatment, the ENCB can establish a direct block of neural activity, thereby eliminating the pain. Additionally, the ENCB can be administered without causing electrochemical damage. An example method can include: placing at least one electrode contact in electrical communication with a region of a subject's spinal cord; applying an electrical nerve conduction block (ENCB) to a nerve in the region through the at least one electrode contact; and blocking neural activity with the ENCB to reduce the pain or other unwanted sensation in the subject.

The present invention is directed to a device and method for monitoring and assessment of movement disorder symptoms. The device and method disclosed herein are particularly amenable to remote monitoring of a subject's movement disorder symptoms. Briefly stated, in certain preferred embodiments of the present invention the movement disorder monitoring device accompanies a subject to a remote location where the device is used to record data relating to the severity of a subject's movement disorder symptoms over a period of time. This data is then subsequently used by physicians or other clinicians in optimizing and assessing treatment options directed at alleviating a subject's movement disorder symptoms. The method and device of the present invention can be used to monitor symptoms of a number of movement disorders including but not limited to dystonia, essential tremor, Huntington's disease, various ataxias, multiple sclerosis, psychogenic tremor, and Parkinson's disease.

In some examples, a medical device is configured to deliver sub-threshold electrical stimulation therapy to a patient at a stimulation intensity that is significantly less than a perception or paresthesia threshold intensity level for the patient. The medical device may determine the particular intensity level for the patient through a titration process. The medical device may titrate automatically or based upon the input of the patient, a clinician or a physician.

Devices, systems, and techniques are described for identifying stimulation parameter values based on electrical stimulation that induces dyskinesia for the patient. For example, a method may include controlling, by processing circuitry, a medical device to deliver electrical stimulation to a portion of a brain of a patient, receiving, by the processing circuitry, information representative of an electrical signal sensed from the brain after delivery of the electrical stimulation, determining, by the processing circuitry and from the information representative of the electrical signal, a peak in a spectral power of the electrical signal at a second frequency lower than a first frequency of the electrical stimulation, and responsive to determining the peak in the spectral power of the electrical signal at the second frequency, performing, by the processing circuitry, an action.

This application is generally related to systems and methods for providing a medical therapy to a patient by tracking patient activity and adjusting medical therapy based on occurrence of different types of activities performed by the patient while automatically rescheduling stimulation programs based on detected patient activity.

An implantable medical device (IMD) includes therapy delivery circuitry, sensing circuitry, and processing circuitry. The processing circuitry is configured to determine one or more sleep apnea therapy parameters, control the therapy delivery circuitry to deliver sleep apnea therapy via a first set of electrodes implantable within the patient in accordance with the one or more sleep apnea therapy parameters, and at least one of: (1) monitor a cardiac signal sensed with the sensing circuitry, or (2) determine one or more cardiac therapy parameters, and control the therapy delivery circuitry to deliver cardiac therapy via a second set of electrodes implantable within the patient in accordance with the one or more cardiac therapy parameters.

A medical apparatus for a patient comprises an external system and an implantable system. The external system is configured to transmit one or more transmission signals, each transmission signal comprising at least power or data. The implantable system is configured to receive the one or more transmission signals from the external system, and to deliver stimulation energy to the patient. Methods of delivering stimulation energy are also provided.

An implantable medical device for treating breathing disorders such as central sleep apnea wherein stimulation is provided to the phrenic never through a transvenous lead system with the stimulation beginning after inspiration to extend the duration of a breath and to hold the diaphragm in a contracted condition.
