A system is provided for driving an implantable neurostimulator lead, the lead having an associated plurality of electrodes disposed in at least one array on the lead. The system comprises an implantable pulse generator (IPG), the IPG including an electrode driver, a load system for determining load requirements, an IPG power coupler, and an IPG communication system. The system also includes an external unit, which includes an external variable power generator, an external power coupler, an external communication system, and a controller for varying the power level of the variable power generator.

A method for treating nerves in a nasal cavity starts with identifying a patient having a condition occurring outside the nasal cavity. The method then involves activating a console attached to a radiofrequency stylus, advancing a distal tip of the radiofrequency stylus into a nostril of the patient, contacting nasal mucosa lining the nasal cavity with a treatment surface of the distal tip, and delivering radiofrequency energy from one set of bipolar electrodes on the treatment surface of the distal tip to a second set of bipolar electrodes on the treatment surface, to treat at least one nerve underlying the nasal mucosa. Treating the nerve (or nerves) involves modulating activity of the nerve to ameliorate the condition occurring outside the nasal cavity.

Selective high-frequency spinal cord modulation for inhibiting pain with reduced side effects and associated systems and methods are disclosed. In particular embodiments, high-frequency modulation in the range of from about 1.5 KHz to about 50 KHz may be applied to the patient's spinal cord region from an epidural, cervical location to address at least one of high back pain, mid-back pain, low back pain, and leg pain without creating paresthesia in the patient.

The present disclosure generally relates to a system for treating headaches and other pain associated with the occipital nerves. More particularly, the disclosure relates to a system of treating pain by selectively activating specific nerve fibers with a single, fault-resistant contact situated proximate to, but not in direct contact with, portions of one or more the occipital nerves. Additional measures ensure the lead does not migrate or fracture, resulting in long-lasting pain relief.

A method for delivering energy as a function of degree coupling may utilize an external unit configured for location external to a body of a subject and at least one processor associated with the implant unit and configured for electrical communication with a power source. The method may determine a degree of coupling between the primary antenna and a secondary antenna associated with the implant unit, and regulate delivery of power to the implant unit based on the degree of coupling between the primary antenna and the secondary antenna.

A medical device control unit is provided. The control unit may include at least one processing device, a circuit electrically coupled to the at least one processing device, and a flexible housing configured to contain the at least one processing device and the circuit. The flexible housing may include at least one connection portion configured to engage a connector protruding from a flexible carrier, and at least one electrical contact electrically coupled to the circuit and configured to establish an electrical connection with an exposed electrical contact on the flexible carrier when the connection portion is engaged with the at least one connection portion.

Described are systems and methods for preventing, diagnosing, and/or treating one or more medical conditions. The medical conditions can be ocular and/or neurological diseases, disorders, and/or conditions. The systems and methods can employ a microstimulator that is configured to be placed within an anatomical structure of a subject. The microstimulator can be capacitively linked to an external electronic device to provide neuromodulation to a biological target site proximal to the anatomical structure. The microstimulator can include a body and an electrically conductive insert arranged within the body to create a capacitively coupled link with the external electronic device. The electrically conductive insert can receive a power signal from an external electronic device and convert the power signal to deliver a therapy signal to the biological target site.

In certain variations, systems and/or methods for electromagnetic induction therapy are provided. One or more ergonomic or body contoured applicators may be included. The applicators include one or more conductive coils configured to generate an electromagnetic or magnetic field focused on a target nerve, muscle or other body tissues positioned in proximity to the coil. One or more sensors may be utilized to detect stimulation and to provide feedback about the efficacy of the applied electromagnetic induction therapy. A controller may be adjustable to vary a current through a coil to adjust the magnetic field focused upon the target nerve, muscle or other body tissues based on the feedback provide by a sensor or by a patient. In certain systems or methods, pulsed magnetic fields may be intermittently applied to a target nerve, muscle or tissue without causing habituation.

Non-invasive electrical nerve stimulation devices and magnetic stimulation devices are disclosed, along with methods of treating medical disorders using energy that is delivered noninvasively by such devices. The disorders comprise migraine and other primary headaches such as cluster headaches, including sinus symptoms that resemble an immune-mediated response (“sinus” headaches), irrespective of whether those symptoms arise from an allergy that is co-morbid with the headache. The disclosed methods may also be used to treat other disorders that may be co-morbid with migraine headaches, such as anxiety disorders. In preferred embodiments of the disclosed methods, one or both of the patient's vagus nerves are stimulated non-invasively. In other embodiments, parts of the sympathetic nervous system and/or the adrenal glands are stimulated.

A medical apparatus for a patient comprises an implantable system. The implantable system comprises a first implantable device comprising: at least one implantable functional element configured to deliver stimulation energy to tissue of the patient; and an implantable controller configured to provide a stimulation waveform to the at least one implantable functional element, the stimulation waveform comprising one or more stimulation parameters. The apparatus is configured to randomly vary at least one of the one or more stimulation parameters. Methods of providing stimulation energy with randomly varying stimulation parameters are also provided.
