Patent number: 8504159Abstract: Electromagnetic signal delivery for tissue affected by neuronal dysfunction, degradation, damage, and/or necrosis, and associated systems and methods are disclosed. A method in accordance with one embodiment of the invention includes identifying an affected region, with the affected region including neuronal tissue that, at least during a pre-dysfunctional period, was in neural communication with neuronal tissue in a dysfunctional region. The affected tissue can be functionally adversely affected by neuronal dysfunction in the dysfunctional region. The method can further include applying electromagnetic signals to the neuronal tissue in the affected region. For example, the electromagnetic signals can be applied to a hypo-active neural region that is not physically damaged, and has been identified as likely to recover at least in part as a result of electromagnetic signals. Signals can be applied at sub-threshold levels to cortical and/or subcortical regions.Type: GrantFiled: May 10, 2011Date of Patent: August 6, 2013Assignee: Advanced Neuromodulation Systems, Inc.Inventors: Brad Fowler, Bradford E.

Publication number: 20120253442Abstract: A device and method for intracranial electrical stimulation to effectuate a change in neural-functions of a patient, by electrical stimulating the brain at a site where neuroplasticity is occurring or is expected to occur, where the stimulation site may be different than the region in the brain where neural activity is typically present to perform the particular neural function according to the functional organization of the brain. In one embodiment in which neuroplasticity is related to the neural-function occurs in the brain, identifying the location where such neuroplasticity is present or expected to occur. Where neuroplasticity is not occurring in the brain, an alternative aspect is to induce neuroplasticity at a stimulation site where it is expected to occur. The methods can use electrical pulses that increase the resting membrane potential of neurons at the stimulation site to a subthreshold level.Type: ApplicationFiled: April 3, 2012Publication date: October 4, 2012Inventors: Bradford Evan Gliner, Brad Fowler, Andrew D.

Patent number: 8090446Abstract: Methods for providing electrical stimulation therapy to a cortex of a patient via a plurality of electrodes proximate to the cortex and a pulse generator implanted in the patient. One embodiment of a method in accordance with the invention comprises determining whether the current applied via the plurality of electrodes results in a sufficient current density in the cortex. The current density, for example, may need to be high enough to induce a response in the patient for determining the activation threshold of the specific stimulation site, or the current density may need to be high enough to perform a specific therapy. If the current density is not sufficient, the method continues by selecting a subset of the plurality of electrodes, and applying electrical current to the cortex via the subset of the electrodes.Type: GrantFiled: April 8, 2008Date of Patent: January 3, 2012Assignee: Advanced Neuromodulation Systems, Inc.Inventors: Brad Fowler, Justin Hulvershorn, Bradford E.
