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.

Adaptive software configuration for a medical device

This document describes, among other things, a method of operating a medical device comprising 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.

Transthoracic cardiac stimulation therapies provide for detection and treatment of cardiac asystole subsequent to delivery of a defibrillation therapy. A pacing therapy is transthoracicly delivered to terminate detected cardiac asystole using residual energy from a defibrillation energy storage source. The residual energy usable for the pacing therapy is sufficient to transthoracicly deliver at least one pacing pulse, and is typically sufficient to deliver a series of pacing pulses, prior to depletion of the defibrillation energy storage source. Detection of cardiac asystole is performed following delivery of each pacing pulse, and subcutaneous pacing support is terminated in response to detecting cardiac asystole termination.

Subcutaneous cardiac stimulator employing post-shock transthoracic asystole prevention pacing

An apparatus and method for delivering defibrillation shock therapy employing a multi-terminal pulse output circuit. In such a circuit, at least three electrode lead terminals are switchably connected to the positive and negative terminals of an energy storage capacitor. By serially switching selected electrode lead terminals to the capacitor terminals, a variety of shock pulse waveforms may be generated.

A cardiac rhythm management system includes an electrosurgery mode of operating an implantable cardiac rhythm management device, such as a pacemaker, defibrillator, or pacer/defibrillator. In electrosurgery mode, certain device parameters are programmed to particular electrosurgery mode values in order to increase the immunity of the implanted device to electromagnetic interference during electrosurgery. Electrosurgery mode device parameter values include both previously-programmed values and different values that are particular to electrosurgery mode. Electrosurgery mode is initiated by an external programmer, which enables electrosurgery mode parameters, displays an indicator to the user, and disables further device parameter programming until electrosurgery mode is terminated by a user request from the external programmer. Electrosurgery mode includes asynchronous pacing, such as DOO mode providing atrial and ventricular pacing at previously programmed rate, AV delay, amplitudes, and pulse widths. Sensing of intrinsic cardiac signals, sensor rate modulation, and tachyarrhythmia detection and therapy are all turned off during electrosurgery mode.

Systems, structures, and methods are provided to share information in systems including implantable medical devices. Information acquired or generated in the systems is made available so that components of the systems or implantable medical devices can use it without having to reacquire such information.
