Analysis of induced electrical currents from magnetic field coupling inside implantable neurostimulator leads.

Background: Over the last decade, the number of neurostimulator systems implanted in patients has been rapidly growing. Nearly 50, 000 neurostimulators are implanted worldwide annually. The most common type of implantable neurostimulators is indicated for pain relief.

Electromagnetic compatibility of implantable neurostimulators to RFID emitters.

Background: The objective of this study is to investigate electromagnetic compatibility (EMC) of implantable neurostimulators with the emissions from radio frequency identification (RFID) emitters.

Methods: Six active implantable neurostimulators with lead systems were tested for susceptibility to electromagnetic fields generated by 22 RFID emitters. These medical devices have been approved for marketing in the U.

Application of MEMS technology and engineering in medicine: a new paradigm for facial muscle reanimation.

Translational research may lead to development of micro-electromechanical system-based devices to treat muscle and nerve dysfunctions whose current treatments are inadequate and, at best, palliative. This paper discusses the development of engineered microsystems as a treatment option for palsies of the seventh cranial nerve and the potential application of these devices as a platform technology for treatment of other nervous dysfunctions. The engineering techniques for electrical and chemical stimulation of denervated muscle are discussed along with current caveats from clinical and engineering standpoints.
