A method for manufacturing a lead includes forming an elongated multi-lumen conductor guide defining a central stylet lumen and a plurality of conductor lumens arranged around the stylet lumen. The multi-lumen conductor guide is twisted to form at least one helical section where the plurality of conductor lumens each forms a helical pathway around the stylet lumen. Each of the helical pathways of the at least one helical section has a pitch that is no less than 0.04 turns per centimeter.

Systems and methods for making and using improved leads for electrical stimulation systems

Improved external chargers for charging an implantable medical device, and particularly useful in charging a plurality of such devices, are disclosed. Each of the various embodiments include a plurality of field customization coils for customizing the magnetic charging field generated by the external charger such that the magnetic charging field is not radially symmetric. For example, one embodiment includes a primary coil with a plurality of field customization coils distributed radially with respect to the coil. The generated magnetic charging field can be rendered radially asymmetric by selectively activating or disabling the field customization coils in response to data quantifying the coupling between the various implants and the field customization coils in the charger. If there is a relatively high coupling between a particular implant and a particular customization coil for example, that customization coil can be activated to counter the magnetic charging field at that location, while still maintaining a relatively high magnetic charging field at the location of other implants that may have lower couplings.

A lead is configured and arranged for brain stimulation. The lead includes a proximal end and a distal end. The proximal end includes a plurality of terminals disposed at the proximal end. The distal end has a non-circular transverse cross-sectional shape and includes a plurality of electrodes disposed at the distal end. A plurality of conductive wires electrically couple at least one of the plurality of electrodes to at least one of the plurality of terminals.

A neurostimulation system and method of providing therapy to a patient implanted with a plurality of electrodes using a plurality of electrical sources is provided. A source-electrode coupling configuration is determined from the electrical sources and electrodes. Electrical current is respectively conveyed between active ones of the plurality of electrical sources and active subsets of the plurality of electrodes in accordance with the determined source-electrode coupling configuration. The total number of the electrodes in the active electrode subsets is greater than the total number of the active electrical sources.

A method for manufacturing a lead includes pre-forming at least one relief section along a length of an elongated conductor having a first end and an opposing second end. The conductor with the pre-formed relief section is inserted into a conductor lumen defined along a length of an elongated lead body. The lead body has a first end and an opposing second end. An electrode is disposed at the first end of the lead body. The first end of the conductor is electrically coupled to the electrode. A terminal is disposed at the second end of the lead body. The second end of the conductor is electrically coupled to the terminal.

Methods for making and using improved leads for electrical stimulation systems

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 method and neurostimulation system for treating a patient are provided. A plurality of pulsed electrical waveforms are respectively delivered within a plurality of timing channels of the neurostimulation system, thereby treating the patient. Sets of stimulation pulses within the pulsed electrical waveforms that will potentially overlap temporally are predicted. Stimulation pulses in the respective pulsed electrical waveforms are temporally shifted in a manner that prevents overlap of the potentially overlapping pulse sets while preventing frequency locking between the timing channels.

A system for performing a neurostimulation trial comprises an external trial stimulator capable of delivering stimulation energy to a plurality of electrodes carried by one or more stimulation leads. The external trial stimulator is configurable to operate in a plurality of stimulation energy delivery modes to respectively emulate one of different neurostimulator types. The system may further comprise a programmer capable of configuring the external trial stimulator to operate in one of the stimulation energy delivery modes. The programmer may be capable of generating a first programming screen capable of allowing a first set of stimulation parameters to be defined for the first neurostimulator type, and a second programming screen capable of allowing a second set of stimulation parameters to be defined for a second neurostimulator type.

Multimodal neurostimulation systems and methods

Electrical energy is transcutaneously transmitted from an external charger to an implanted medical device. The external charger includes a charging head that is selectively shaped to conform to the surface of a patient to enhance charge efficiency and patient comfort. The charging head has a plurality of malleable support members extending through the charging head for affixing the flexible charging head in the selected shape, while the flexible charging head conforms to the surface of the patient. The charging head may also include one or more sensors for determining the shape of a charging coil in the charging head, which cause the charge of the coil to be adjusted based on the coil shape.

Neurostimulation systems and methods for providing therapy to a patient suffering from a symptom of a disease that latently responds to electrical stimulation therapy are provided. First electrical stimulation energy is conveyed to or from a tissue region of the patient in accordance with a first set of stimulation parameters, thereby affecting the symptom. A predetermined period of time estimated for the symptom to resolve in response to electrical stimulation therapy is allowed to elapse. Second electrical stimulation energy is conveyed to or from the tissue region in accordance with a second set of stimulation parameters different from the first set of stimulation parameters.

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.
