A hand-held device includes a housing with a controller having a signal generator, an electrode for delivering electrical signals, and a conductive surface configured as a return path for the electrical signals. In certain implementations, the electrode is repositionable with respect to the housing. The patient can self-apply the hand-held device by pressing it against areas in need of pain relief. The device may include a pressure-sensitive gating switch to control delivery of the stimulation therapy. In certain embodiments, the electrode is a rollerball electrode. The device may include a chamber for retaining and dispensing conductive gel to the therapy site. In certain approaches, the device includes an electrode support for coupling an electrical stimulation system to the head for hands-free electrical stimulation therapy.

An example of a neurostimulation system may include a storage device, a programming control circuit, and a graphical user interface (GUI). The storage device may be configured to store individually definable waveforms. The programming control circuit may be configured to generate stimulation parameters controlling the delivery of the neurostimulation pulses according to a pattern. The GUI may be configured to define the pattern using one or more waveforms selected from the individually definable waveforms. The GUI may display waveform tags each selectable for access to a waveform of the individually definable waveforms, and display a waveform builder in response to selection of one of the waveform tags. The waveform builder may present a graphical representation of the accessed waveform and allow for the accessed waveform to be adjusted by editing the graphical representation of the accessed waveform on the GUI.

The current technology is relevant to a system having a programming device capable of communication with an implantable medical device, where the programming device is configured to identify a patient condition comprising the patient's inability to exercise to a desired capacity, configured to notify a clinical user of the identified condition and configured to identify a therapy appropriate for the identified condition.

Some computer-assisted methods include: presenting configuration options to a user of the implanted stimulator device, the configuration options comprising stimulation parameters for the implanted stimulator; receiving a user specification of the configuration options in response to the presented configuration options; receiving user feedback when the user specified configuration options are implemented at the implanted stimulator device, the user feedback comprising a quantitative index of pain resulting from implementing the user specified configuration options on the implanted stimulator device; building a user profile for the user based on the user specified configuration options and the user feedback, the user profile including the user specified configuration options as well as the corresponding quantitative index of pain; and selecting at least one configuration option based on the user profile when the configuration options are subsequently presented to the user for a later treatment.

Methods for systematically testing a plurality of therapy programs in a spinal cord modulation system, and associated systems are disclosed. A representative method comprises loading a plurality of therapy programs into a signal generator, wherein individual therapy programs include parameters specifying electrode configuration, signal amplitude, and/or signal frequency. The programs are automatically activated for an automatically instructed period of time. The method includes automatically changing from one therapy program to another after the instructed period of time. The patient is queried for patient input corresponding to the therapy programs. The patient input is received via a remote. The patient input is correlated with a corresponding time of day and recorded in the signal generator. Thereafter, the patient input is retrieved from the signal generator.

An exemplary sound processor included in a cochlear implant system associated with a patient 1) receives, from a fitting system while the sound processor is communicatively coupled to the fitting system, a command that sets a control parameter associated with the cochlear implant system to an initial value and data representative of a target value associated with the control parameter, 2) detects a decoupling of the sound processor from the fitting system, the decoupling resulting in the sound processor being in a non-fitting state, and 3) gradually adjusts, while the sound processor is in the non-fitting state, the control parameter from the initial value towards the target value in accordance with an adaption time course associated with the control parameter. Corresponding systems and methods are also disclosed.

The present disclosure describes systems and methods for recording electrical activity, such as local field potentials. The system can include a recording patch that is placed inline between an implanted neurological lead and an implantable pulse stimulator. The recording patch can include recording and amplification circuitry that detects, records, and amplifies electrical activity (also referred to as signals) from a target site. The system can be used to select over which of the lead's electrodes therapeutic stimulations are delivered.

A system and method of providing therapy to a patient using a plurality of electrodes implanted within the patient. A virtual multipole configuration is defined relative to the plurality of electrodes. The distance between each of a group of the electrodes and a virtual pole of the virtual multipole configuration is determined. A stimulation amplitude distribution is determined for the electrode group based on the determined distances, thereby emulating the virtual multipole configuration. Electrical energy is conveyed from the electrode group in accordance with the computed stimulation amplitude distribution.

A system, such as an IMD system, includes a tissue conductance communication (TCC) transmitter configured to generate a beacon signal by generating a carrier signal and modulating a first property of the carrier signal according to a first type of modulation. The TCC transmitter is configured to generate a data signal subsequent to the beacon signal by generating the carrier signal and modulating a second property of the carrier signal different than the first property according to a second type of modulation different than the first type of modulation.
