Description

A model of the world's first fully implantable cardiac pacemaker, made and donated to the museum by AUB Modelmaking student Kate Evans. This pacemaker was invented by Doctors Rune Elmqvist and Ake Senning, and was fitted to a patient in Sweden in 1958. The experimental unit encased components such as pulse generating circuitry and batteries, within a biocompatible, synthetic epoxy resin called Araldite, which was originally cast in a Kiwi shoe polish tin. The plastics in the original pacemaker provided the vital hermetic seal to prevent the ingress of bodily fluids from short circuiting the unit and two polyethylene coated suture wires connected the unit to the patient's heart.
