EBR System’s Wireless Pacemaker

EBR Systems, Inc., founded in 2003 and headquartered in Sunnyvale, CA, is developing the WiCS® Wireless Cardiac Stimulation technology to eliminate cardiac pacing leads, historically a major source of complications and reliability issues.  The startup was spun out of research by founder Debra Echt, a former professor of medicine and a cardiologist at Vanderbilt University.

Nanostim’s Leadless Pacemaker

Nanostim is an early-stage AIMD company in Milpitas, CA that is developing a pacemaker that can be implanted inside the heart through a catheter.  The tiny device is attached directly to the heart, eliminating the need for leads. In May 2011 Nanostim announced that St. Jude Medical had made a substantial investment in the company. The company is operating in

Glucose Fuel-Cell-Powered Implantable Devices

  My friend, Dr. Alain Ripart – the Chief Scientific Officer at Ela Medical (now part of Sorin) showed me this interesting contraption from his personal collection.  It is an experimental glucose-powered pacemaker developed in the 1970s.  It generated electricity by acquiring its fuel (glucose) directly from a living body to generate enough current to charge two NiCd cells

American Optical’s Nuclear Pacemaker (1970’s)

Barouh Berkovits at American Optical Co of Boston, MA designed the first “Demand Pacemaker” – what we now know as a VVI pacemaker.  As other companies in the 1970s, American Optical developed a nuclear-battery-powered version of their pacemaker. American Optical used a 3Ci Pu-238 Radioisotope Thermal Generator (RTG) produced by Fred Hittman’s Hittman Nuclear Development Corp. (Model NB-200).  It consisted of a tiny 8 Ci

Medtronic’s Atomic Pacemaker (early 1970’s)

In the late 1960s Medtronic – today the largest manufacturer of implantable medical devices in the world – teamed up with Alcatel, a French company, to design a nuclear-powered pacemaker. The first human implant of the device took place in Paris in 1970. The nuclear battery in the Medtronic device used a tiny 2.5 Ci

CCC del Uruguay’s Atomic Pacemaker (1972)

This nuclear pacemaker was manufactured ca. 1972 by Dr. Orestes Fiandra’s CCC del Uruguay. It was powered by a McDonell-Douglas Betacel 400 which had promethium-147 sandwiched between semiconductor wafers. As the radioactive promethium isotope decays, it emits β-particles (electrons). The impact of the β-particles on a p-n junction causes a forward bias in the semiconductor

CCC del Uruguay’s Early Mercury-Cell Pacemaker (1969)

This is one of my most prized possessions.  It is one of the very first pacemakers produced by CCC del Uruguay in 1969.  It was given to me by my friend, the late Dr. Orestes Fiandra, founder of CCC del Uruguay. On February 2, 1960, Dr. Orestes Fiandra and Dr. Roberto Rubio accomplished the first succesful long-term

CCC Medical – Top OEM to AIMD Start-Ups

CCC is one of the oldest pacemaker manufacturers in the world. It was founded in 1969 by Dr. Orestes Fiandra, who performed the first succesful, human, long-term pacemaker implant in the world. This was achieved in Uruguay on February 2, 1960 by Dr. Orestes Fiandra and Dr. Roberto Rubio. The pacemaker was manufactured by Dr. Rune Elmqvist of

Omikron Scientific – Israeli Pacemaker Company (1979-1985)

Omikron Scientific was a small-scale pacemaker company founded in Rehovot, Israel in 1979.  The company stopped pacemaker production in 1985. Besides pacemakers, Omikron also produced a skin substitute called Omniderm, which was a thin, transparent, flexible membrane. It was used when a biological dressing would otherwise have been used. Omikron’s pacemakers were all VVI and featured gradual decline Magnet Rate

MTC’s Piezos Used for Wireless Power Transmission in EBR’s Wireless Pacemaker

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.

NEXUS Pacemaker with Hemodynamics Sensing and Patient Alert

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”.
