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 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

ImThera Medical’s Aura6000 Implantable System for the Treatment of Sleep Apnea

The aura6000 is based on ImThera’s Targeted Hypoglossal Neurostimulation (THN) Sleep Therapy™ delivering neurostimulation to the tongue during sleep. The system is comprised of a surgically‐placed multi‐contact electrode specifically designed for the Hypoglossal nerve, and a lead that connects the electrode to a programmable implantable pulse generator (IPG) that is placed in the anterior chest wall.

ST Microelectronics Developing Implantable SOCs

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

Tantalus II System for Treating Metabolic Syndrome

MetaCure’s TANTALUS II device is an advanced implantable electrical stimulator used to apply gastric stimulation. It works by enhancing the activity of gastric muscles only when the patient eats, which modifies hormone secretion, favorably affecting glucose and fat metabolism. At the same time, the stimulation causes the patient to feel satiated sooner and consume less
