From: Feasibility of Leadless Cardiac Pacing Using Injectable Magnetic Microparticles

The proposed modality for inducing cardiac pacing and features of its components: the magnetic microparticles (IMPs) and electromagnet.
An illustration of our proposed modality and its setting (a, Figure courtesy of Yair Vardi). The IMP morphology is viewed by SEM (b) and their size distribution analyzed by static light scattering (c) A color map of the magnetic induction (d) and the magnetic induction intensity and gradient as a function of the distance from the electromagnet tip (e) generated by the electromagnet, as obtained from the computerized model.
