An apparatus comprises a magnetic field detection circuit, a cardiac signal sensing circuit, a memory circuit, a control circuit, and an arrhythmia detection circuit. The cardiac signal sensing circuit generates a cardiac signal representative of cardiac activity of a subject when coupled to sensing electrodes. The control circuit is operatively coupled to the magnetic field detection circuit; the cardiac signal sensing circuit, and the memory circuit. The control circuit stores cardiac signal data determined using the sensed cardiac signal, receives an indication of magnetic field detection by the magnetic field detection circuit, stores data obtained using the sensed cardiac signal during the magnetic field detection, and stores an identifier indicating the magnetic field detection in association with the data. The arrhythmia detection circuit processes the cardiac signal data to detect a cardiac arrhythmia event and confirm the cardiac arrhythmia event according to the magnetic field indication.

The apparatuses, systems, and methods may include a first electrode and a second electrode and a scaffold assembly configured to support the first electrode and the second electrode.

Implantable medical device having two electrodes in the header

Insertable cardiac monitoring device designed for the mri environment

An example of a method performed by an implantable medical device (IMD) to deliver a therapy to a patient may include delivering the therapy to the patient, detecting a trigger that is controlled by the patient or a caregiver to the patient, and determining if at least one feature of the IMD for responding to a trigger is enabled. The IMD may be configured to allow the patient or the caregiver to the patient to enable the at least one feature. The method may further include, when the at least one feature is enabled, automatically implementing the at least one enabled feature in response to the detected trigger, including automatically suspending the therapy in response to the detected trigger and automatically restoring the therapy after a defined period after the detected trigger.

Patient control of therapy suspension

Implanted electrodes can be used to deliver electrical stimulation signals to areas near blood vessels, nerves, or other internal body locations. In an example, an electrode can be implanted in a cervical location and can be used to measure dimensional changes in an artery using impedance plethysmography. Measured artery dimensional changes can be used to determine one or more physiological parameters associated with a patient's health status, such as pulse transit time, relative pulse pressure, or aterial compliance, among others. These parameters can be used to monitor a patient health status or to modulate a patient's therapy, among other uses. In some examples, an electrode configured to deliver an electrostimulation signal to nerve tissue can be used to provide non-neurostimulating electrical stimulation plethysmography signals near a blood vessel.

Method and apparatus for determination of physiological parameters using cervical impedance

Aspects herein include an implantable medical device, such as an implantable cardiac rhythm management device. The implantable medical device can include a housing, control circuitry disposed within the housing, and telemetry circuitry in electrical communication with the control circuitry. The control circuitry can be configured to execute a post-procedural system check procedure after the expiration of a preselected first time period. The first time period can be greater than or equal to 0.5 hours and less than or equal to 48 hours. In various aspects, the post-procedural system check procedure can include measuring diagnostic properties for one or more electrodes of an electrical stimulation lead attached to the implantable medical device. The first time period can begin to elapse after detection of a triggering event or a command by a system operator.

Implantable medical devices and methods including post-procedural system diagnostics

A method and system for providing an indication of delivery of a neural stimulation therapy is disclosed. In an example, a method may include identifying current timing of an intermittent neural stimulation (INS) programmed in an implantable medical device (IMD) where the programmed INS includes alternating stimulation ON and stimulation OFF times and a timing for delivering stimulation bursts of a plurality of stimulation pulses during the stimulation burst ON times. An indication of the current timing of the INS may be provided using an INS indicator of an external device.

Method and system for indicating neurostimulation delivery

An implantable medical device is powered by a battery to deliver one or more therapies including at least one non-life-sustaining therapy such as neural stimulation for enhancing quality of life of a patient. When the battery approaches its end of life, the implantable medical device reduces power consumption of the neural stimulation (e.g., intensity of the neural stimulation) for extending the remaining battery life while maintaining a certain amount of therapeutic benefits for the patient. In one embodiment, the intensity of the neural stimulation is reduced in a tiered manner. In one embodiment in which the implantable medical device also delivers at least one life-sustaining cardiac stimulation therapy, the neural stimulation is disabled or adjusted to reduce its power consumption (e.g., intensity) while the intensity of the cardiac stimulation therapy is maintained when the battery is near its end of life.

Implantable medical device with control of neural stimulation based on battery status

An apparatus comprises a therapy circuit that provides a neural stimulation current, an impedance measurement circuit that measures a value of impedance at the output of the therapy circuit, a supply voltage generating circuit that provides an adjustable supply voltage value to the therapy circuit including a first supply voltage value when in a first mode, and a control circuit communicatively coupled to the therapy circuit, the impedance measuring circuit, and the supply voltage generating circuit. The control circuit, upon receiving an indication to exit the first mode, initiates an impedance measurement by the impedance measurement circuit, determines the second supply voltage value using the impedance measurement, and initiates a change from the first supply voltage value to the second supply voltage value. The second supply voltage value is sufficient to operate the therapy circuit and to provide a specified load current value to the measured impedance.

Power supply management for implantable neurostimulation devices

An apparatus comprises a transceiver configured to communicate wirelessly with an IMD and a processor communicatively coupled to the transceiver. The processor is configured to detect an error in a data unit received from the IMD, transmit a series of synchronization signals during an uninterrupted communication sequence, and receive, for each synchronization signal, a new data unit and the number of requested duplicate data units from the IMD. Each synchronization signal includes an echo code, wherein the echo code corresponds to a request for a number of duplicate data units to be sent in response to detecting the error in the data unit received during said uninterrupted communication sequence. The number of duplicate data units corresponds to a value of the echo code, and a duplicate data unit corresponds to a data unit previously transmitted by the IMD during said uninterrupted communication sequence.

On-demand retransmission of data with an implantable medical device

A method of operating a medical device comprises updating a regulatory approval status stored in at least one of the medical device or a second device operable to communicate with the medical device, and enabling or disabling the at least one function in the medical device based on the regulatory approval status. The regulatory approval status corresponds to at least one function performable by the medical device.
