Cameron Health’s Leadless Implantable Defibrillator

Cameron Health was founded in 2000 in San Clemente, CA to develop a leadless implantable defibrillator. The device does not require a lead to be implanted into the heart. Instead, the device has a lead that is tunneled beneath the skin from the upper left chest below the level of the clavicle to the level of about

BetaBatt’s Modern Betavoltaic Cells to Power Active Implantable Devices

Image Credit: University of Rochester Nuclear energy cells that converted the impact of the β-particles on a p-n junction were developed in the 1970s.  One example was CCC’s atomic pacemaker, which was powered by a promethium-147  McDonell-Douglas Betacel 400. Lately, BetaBatt Inc. of Houston, TX licensed beta-voltaic technology developed  at the University of Rochester to develop an

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

Arco Medical’s Nuclear-Powered Pacemaker (ca.1974)

An isotopic thermoelectric generator was developed in the US by Numec Corporation under a contract from the US Atomic Energy Commission and sold for $3,200 (back in 1974). The thermopile consisted of doped bismuth telluride pairs that were placed in a parallel/series arrangement to generate some 300 μW of power to run this Arco Medical

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

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
