摘要:
A method and programmer for programming a neurostimulation device are provided. The method comprises varying a first stimulation parameter under user control, automatically varying a second stimulation parameter, generating a plurality of stimulation parameter sets from the varied first and second stimulation parameters, outputting a pulsed electrical waveform from the neurostimulation device between a plurality of electrodes in accordance with the stimulation parameter sets, such that neural tissue is stimulated without undergoing neurological accommodation that would otherwise occur if the second stimulation parameter were not varied, and programming the neurostimulation device with a new set of stimulation parameters based on a result of the neural tissue stimulation The programmer comprises a user interface capable of receiving an input from a user, a processor configured for performing the previous steps, and output circuitry configured for transmitting the stimulation parameter sets and the new stimulation parameter set to the neurostimulation device.
摘要:
A method for treating a patient having a dysfunction using a stimulation lead within the brain of a patient is provided. The stimulation lead carries a plurality of electrodes adjacent to a plurality of brain regions. Pulsed electrical waveforms having different sets of stimulation parameters are generated and then concurrently delivered to the plurality of electrodes, thereby concurrently stimulating the plurality of brain regions to treat the dysfunction.

Methods of providing therapy to a patient are provided. In one method, the patient has a neuron to which a sub-threshold biological electrical stimulus is applied. The method comprises applying electrical noise energy to the neuron, wherein resonance between the biological electrical stimulus and the electrical noise energy is created, such that an action potential is propagated along the axon of the neuron. In another method, the patient has a neuron to which a supra-threshold biological electrical stimulus is applied. This method comprises applying supra-threshold electrical noise energy to the neuron, thereby preventing an action potential from being propagated along the axon of the neuron. Still another method comprises applying an electrical stimulus to a neuron, and applying supra-threshold electrical noise energy to the neuron, thereby preventing or reversing any neurological accommodation of the neuron that may occur in response to the electrical stimulus.

A burr hole plug comprises a plug base including a flange configured for being mounted around a burr hole, an aperture through which an elongated medical device may pass, and tabs configured for extending within the cranial burr hole to center the plug base relative to the cranial burr hole. The burr hole plug further comprises a retainer configured for being mounted within the aperture of the plug base to secure the medical device. A method may comprise locating the plug base within a burr hole, such that the tabs are disposed within the burr hole to center the plug base relative to the cranial burr hole, introducing the elongated medical device through the cranial burr hole and into the brain tissue of the patient, mounting the retainer within the aperture of the plug base, and actuating the retainer to secure the medical device.
摘要:
A method for determining a change in position of a neurostimulation lead relative to a stimulation target tissue of a patient is provided. The method comprises implanting a first proximity sensor on a surface of the patient, implanting a second proximity sensor on the surface of the patient, measuring a change in a distance between the first and second proximity sensors, and inferring the change in position of the lead relative to the stimulation target tissue from the measured change in distance. The method further comprises inferring an increase in a distance between the lead and the stimulation target tissue when the distance between the first and second proximity sensors increases. The method also comprises conveying electrical stimulation energy to therapeutically stimulate the stimulation target tissue, and modulating a stimulation parameter in response to the measured change in distance.
