MEMS for Medical Devices

Keith Maile, Ph.D.
Boston Scientific
Fellow Engineer

MEMS are ubiquitous and are present in many industrial, automotive, aerospace and consumer applications.  On a typical day, we directly interact with these without even knowing it: such as cell-phones, computers, gaming controllers and automobiles.  Although, their application to medical devices is at a slower pace, they have been in use in pacemakers since the 1980’s and their use is clearly accelerating.  In addition, they have also enabled some revolutionary treatment of diseases.

In this presentation, we will look at a brief history and broader market for MEMS, then dive into their medical applications with an emphasis in the medical implantable market-which is typically viewed as the most lucrative.

Brief Biography:
Keith R. Maile, PhD  (BSEE 1986, MSEE 1990, PhD 1993) is an expert in defining analog architecture, selecting/designing physiological and physical sensors, and analog low-power CMOS circuit design for implantable medical applications.  In his 25 years of experience, he has been employed by three companies (Honeywell:1986-1989, Boston Scientific-formerly Guidant:1989-2000, 2002-present and Applied Micro Circuits Corp: 2000-2002).  Most of his tenure was spent at Guidant/Boston Scientific where he worked on both platform-designs for near-term products (which provided the main revenue stream) as well as future product and feature concepts.  In these roles, he performed as a technical leader of teams for the hardware development as well as performing as an individual contributor in analog circuit design and sensor design for both physical and physiologic needs.  

He spent 2 years at AMCC focusing on the development of analog high-speed bipolar IC’s for 10 and 40Gb/s fiber-optic communication systems.  This work included the development of integrated high-speed circuits, transmission lines and distributed networks.  Products include a 40 Gb/s Modulator Driver based on a distributed amplifier in a 220GHz SiGe IC process. 


He currently has 12 issued and 40 applied for.
