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.
