In his early days, Wilson Greatbatch used to prototype his pacemaker circuits onto a manila folder printed with the circuit’s schematic.
In 2000 he gave this reproduction of his 1961 pacemaker to the North American Society of Pacing and Electrophysiology (NASPE, now the Heart Rhythm Society -HRS).

This item is in the collection of artifacts of the HRS.
Related to the circuit in this picture, Daniel Villamil and I recently published a paper in which we analyzed the earliest battery-powered implantable pacemakers developed independently by Rune Elmqvist (1958) and Wilson Greatbatch (1960), and we reconstructed faithful working replicas to explore the design tradeoffs and constraints that shaped these devices.
