Morgan Technical Ceramics (MTC) announced that its Bedford, Ohio site manufactures the piezoelectric ceramic materials used in EBR Systems, Inc.’s innovative new WiCS® Wireless Cardiac Stimulation System. The PZT (lead zirconate titanate) material made by MTC is critical to the efficiency of the WiCS system, which is powered by a battery with a 10-year lifespan.
Medical Product Manufacturing News announced that ST Microelectronics is developing ultra-low-power Systems On Chip (SOCs) suitable for implantable medical devices. ST Microelectronics’ 65nm features a Vt of only 0.6V that can be used very near threshold. The REISC processor consumes barely 10.8pJ/cycle at 0.6V. This type of technology will certainly enable many new implantable devices
The November issue of Evaluation Engineering carried an article by Tom Lecklider on the amount of work invested by Medtronic to develop and test the Revo MRI pacemaker system. The article is available on-line at Evaluation Engineering (Click here for direct link to the November 2011 issue).
Intermedics’ next-generation pacing platform would have been full of neat features such as: hemodynamic sensing (impedance-based hemodynamic sensor), autocapture (capture verification), autothreshold (self-tuning based on automatic strength-duration curve generation), high-quality digital telemetry, large-volume memory for electrogram storage, non-volatile memory for self-recovery and patient information, advanced noise detection, etc. My favorite feature though was “Patient Alert”.
Impulse Dynamics’ OPTIMIZER™ III Implantable Pulse Generator delivers Cardiac Contractility Modulation (CCM), non-excitatory electrical signals during the myocardial absolute refractory period in synchrony with locally sensed electrical activity. CCM signals are intended to treat patients with symptomatic heart failure despite appropriate medical treatment.
Welcome to implantable-device.com, a blog dedicated to professionals interested in the fascinating world of active implantable medical devices! Let me tell you a bit about myself: I have over twenty years of experience in the design of Medical Electronic Instrumentation, most of it developing active implantable medical devices. In addition to 30 papers and 70
