Increase in Temperature from AIMDs Dissipating Endogenous Heat

Active Implantable Medical Devices generate heat as a result of resistive losses in their circuitry, exothermic reaction in their batteries, eddy-current heating due to inductive recharge, friction between mechanical components, etc.  The European Standard which regulates AIMDs limits the heating of the outer surface of an AIMD to 2ºC above normal body temperature.  Despite the

Why Do So Many Novel Implantables Use a “Boxy” Enclosure?

  Active implantable medical devices are typically enclosed in a hermetically-sealed titanium housing which provides protection of the circuitry and other components. Commonly, Grade 1 titanium is formed into the enclosure using stamping. The pretty, rounded shapes of modern pacemakers and ICDs are achieved by having two enclosure halves shallowly stamped from sheet stock material,

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
