Abstract: Methods, systems, and devices for implantable node are described. The method may include storing, at an implantable stimulation node, a set of stimulation profiles in a memory during a configuration phase. The method may also include receiving a stimulation command corresponding to a stimulation profile of the set of stimulation profiles during a treatment phase. The method may further include delivering stimulation based at least in part on the stimulation profile corresponding to the received stimulation command. In some cases, the system may include an implantable hub, an implantable sensing node, and a sensing device.

Abstract: A method for a wearable cardioverter defibrillator (WCD) system comprises sensing one or more patient parameters from different parts of a body of the patient by the one or more transducers, obtaining a plurality of physiological inputs from the sensed one or more patient parameters, detecting first aspects from each of at least some of the physiological inputs, generating an aggregated first aspect from at least two of the detected first aspects, determining an aggregate analysis score from the aggregated first aspect, and determining whether the aggregate analysis score meets an aggregate shock criterion. The electrical charge is discharged within six minutes from when it is determined that the aggregate shock criterion is met, otherwise the electrical charge is not discharged for at least 19 minutes from when it is determined that the aggregate shock criterion is not met.

Abstract: A method is disclosed for programming a patient's stimulator device using an external device. The method provides a Graphical User Interface (GUI) on the external device that allows the patient to select from a plurality of displayed stimulation modes to program stimulation provided by one or more electrodes of the stimulator device. The external device stores a model derived for the patient, which model comprises information indicative of a plurality of frequency/pulse width/amplitude coordinates predicted to provide optimal stimulation for the patient. Each stimulation mode corresponds with a subset of coordinates defined in accordance with the plurality of coordinates in the model. Selection of one of the stimulation modes limits programming the stimulator device with coordinates that are within the corresponding subset of coordinates.

Abstract: A skin treatment device includes a roller disposed about a rotational axis, with a plurality of flexible, compressive skin contact elements distributed circumferentially about the roller. Compressive elements include a first longitudinal section coupled to the roller, a second longitudinal section with a radially outer skin contact surface extending opposite the first longitudinal section, and a transverse section with one or more web members connecting the first and second longitudinal sections at an angle. The angles of the web members are adapted to generate lateral displacement of the contact surfaces in response to a compressive load. The lateral displacements of adjacent pairs of contact surfaces are defined in opposite directions, parallel and antiparallel to the rotational axis, in order to provide an elastic stretching treatment to the skin. Electrodes can be disposed adjacent the roller, on the housing or between adjacent contact surfaces, in order to provide a current treatment.

Abstract: A system includes a controller module, which includes a storage device, a controller, a modulator, and one or more antennas. The storage device is stored with parameters defining a stimulation waveform. The controller is configured to generate, based on the stored parameters, an output signal that includes the stimulation waveform, wherein the output signal additionally includes polarity assignments for electrodes in an implantable, passive stimulation device. The modulator modulates a stimulus carrier signal with the output signal to generate a transmission signal. The one or more antennas transmit the transmission signal to the implantable, passive stimulation device such that the implantable, passive stimulation device uses energy in the transmission signal for operation, sets the polarities for the electrodes in the implantable, passive stimulation device based on the encoded polarity assignments, generates electrical pulses using the stimulation waveform, and applies the electrical pulses to excitable tissue.

Abstract: In an example, physiological signal(s) are received from physiological sensor(s) configured to measure at least one physiological property of a user. An arousal of at least one characteristic of at least one treatment resistant mood disorder is detected through employment of an estimation method based at least in part on at least one of the physiological signal(s). A value for at least one of a plurality of stimulation parameters is selected based at least in part on at least one of the physiological signal(s). An electric field based at least in part on the arousal is produced. The electric field is configured to stimulate at least a portion of a median nerve of the user transcutaneously. The electric field is based at least in part on at least some of the plurality of stimulation parameters.

Abstract: Devices, systems, and techniques are described for selecting an evoked compound action potential (ECAP) growth curve based on a posture of a patient. The ECAP growth curve defines a relationship between a parameter defining delivery of stimulation pulses delivered to the patient and a parameter of an ECAP signal of a nerve of a patient elicited by a stimulation pulse. In one example, a medical device detects a posture of a patient and selects an ECAP growth curve corresponding to the detected posture. The medical device selects, based on the ECAP growth curve corresponding to the detected posture and a characteristic of a detected ECAP signal, a value for a parameter for defining delivery of the stimulation pulses to the patient and controls delivery of the stimulation pulses according to the selected value for the parameter.

Abstract: An architecture is disclosed for an Implantable Pulse Generator having improved compliance voltage monitoring and adjustment software and hardware. Software specifies which stimulation pulses are to be measured as relevant to monitoring and adjusting the compliance voltage. Preferably, specifying such pulses occurs by setting a compliance monitoring instruction (e.g., a bit) in the program that defines the pulse, and the compliance monitor bit instruction may be set at a memory location defining a particular pulse phase during which the compliance voltage should be monitored. When a compliance monitor instruction issues, the active electrode node voltages are monitored and compared to desired ranges to determine whether they are high or low. Compliance logic operates on these high/low signals and processes them to decide whether to issue a compliance voltage interrupt to the microcontroller, which can then command the compliance voltage generator to increase or decrease the compliance voltage.

Abstract: Techniques for sensing neural responses such as Evoked Compound Action Potentials (ECAPs) in an implantable stimulator device are disclosed. A first therapeutic pulse phase is followed by a second pulse phase, which phases may be of opposite polarities to assist with active charge recovery. The second pulse phase is formed so as to overlap in time with the arrival of the ECAP at a sensing electrode, which second phase may generally be longer and of a lower amplitude. In so doing, a stimulation artifact formed in a patient's tissue is rendered constant, and of a smaller amplitude, when the ECAP is sensed at the sensing electrode, which eases sensing by a sense amp circuit. Passive charge recovery may follow the second phase, which will not interfere with ECAP sensing that has already occurred.
