TL;DR: An implantable device for measuring mechanical heart function of selected heart chambers using a heart contraction detection system that includes a magnetic field sensor is described in this paper, which is used for monitoring signs of acute or chronic cardiac heart failure, to diagnose the condition of the heart, to prescribe appropriate therapies, and to assess delivered pacing therapies.

TL;DR: In this article, an implantable medical device is provided for isolating an elongated medical lead from internal device circuitry in the presence of a gradient magnetic or electrical field, which includes an isolation circuit adapted to operatively connect an internal circuit to the medical lead in a first operative state and to electrically isolate the medical leads from the internal circuit in a second operative state.

TL;DR: In this article, a system and method for reducing the amount of noise caused by inductive elements within an implantable medical device was proposed, which can gradually initiate and terminate the current flow within inductive element such as transformers that are used to charge energy storage devices.

TL;DR: In this paper, the authors present techniques for reducing the interference to telemetry from an implanted medical device caused by a source of controllable noise, such as a defibrillator and a telemetry system.

TL;DR: A prototype bi-directional neural interface system is presented with closed-loop and embedded DSP capabilities, including 32-electrode stimulation capability, eight multiplexed low-noise low-power bio-potential sensing channels with on-chip digital FFT, and a Cortex M3-based microcontroller for implementing closed- loop algorithms.
