Wireless Neural Stimulator With Injectable
Neural stimulator systems with an external magnetic coil to produce changing magnetic fields is applied outside the body, in conjunction with one or more tiny injectable objects that concentrates the induced electric or magnetic field to a highly-targeted location. These systems include a driver circuit for the magnetic coil that allows for high voltage and fast pulses in the coil, while requiring low-voltage power supply that may be powered by a wearable or portable external device, along with the coil and driver circuit.

- 1. A neuromodulation system, comprising at least one elongate device configured for implantation inside the body, the at least one elongate device comprising:
a first and a second electrode; and a diode electrically connected between the first and second electrodes, and wherein the diode is directly connected to the first electrodes.
- 43. A neuromodulation system, comprising:
at least one elongate device comprising first and second electrodes and a diode with a length of less than ten millimeters and a transverse dimension to the length of less than three millimeters, configured for injection adjacent or against a nerve, axon, or neuron; and a magnetic field generator configured to generate an induced and one of a concentrated electric field and a concentrated magnetic field at the at least one elongate device.
- 51. A method of treating a patient, comprising:
inserting at least one elongate device against or adjacent to a nerve, axon, neuron or neural tissue of patient, wherein the device has a length of less than ten millimeters and a transverse dimension to the length of less than three millimeters; positioning at least one a magnetic field generator at a location spaced away from the at least one elongate device; using the at least one magnetic field generator to provide a) an induced and concentrated electric field, or b) a threaded and concentrated magnetic field, to at least one elongate device; and generating a stimulation signal at the least one elongate device using the induced and concentrated electric field or the threaded and concentrated magnetic field; wherein the at least one elongate device comprises:
a first and a second electrode; and
a diode electrically connected between the first and second electrodes, and wherein the diode is directly connected to the first electrodes.
- 69. A method of treating a condition, comprising:
identifying a patient with at least one elongate device implanted at a treatment site, the at least one elongate device comprising first and second electrodes and a diode with a length of less than ten millimeters and a transverse dimension to the length of less than three millimeters, configured for injection adjacent or against a nerve, axon, or neuron; and placing a coil of an external magnetic field generator against a surface of the treatment site of the patient; and applying a magnetic field to the one or more implanted elongate devices to generate therapeutic neural stimulation.
